There is no plan B.

After a non alignment of stars for a planned monday ride with chipps, i decided it was time to hurt myself. Bristol 12 bikefest is just around the corner and i have absolutely no idea what to expect from my body. One way to find out is to push it until it breaks: that way you know your limits.

I decided to take a route we have done once before, as a group, on singlespeeds no less. However this time i wanted to add a little damage....so i took in an extra climb or two just because.



The start was in Dalrigh, just south of tyndrum. There is a short but sweet section of trail from there to tyndrum, and the climb up before the magnificent view of beinn dorain.



From there i clicked the gears up on the Vertigo and booted it to bridge of orchy. By 1 hour i was at victoria bridge carpark, prior to the infamous wades road section over to white corries and glencoe. Why infamous? well general wade has the rare distinction of creating some of the harshest surfaced and ridiculously steep roads in scotland. All this so england could garrison the north in their efforts to defeat the jacobite uprising of 1715. The vibrating, hateful, momentum robbing pain of passing what are left of these roads (and the soldiers who built them would be, err, proud to know that significant stretches still exist) are a real test of a tired biker, and i knew the return leg was going to hurt.



There is always a rush as the buachaille comes into view. Such a monster sat out at the top of glencoe: a guardian of the highlands, and this storied glen. My route cut east though, across rannoch moor.



The trail is initially good, a double track road, and someone has built a reroute section due to a house being constructed in the crop of trees visible from the road or the kingshouse.



Then it starts to deteriorate. You know you need to follow the power lines, but its a real mess. Peat moor usually is. Grin and bear it. To give some idea, here is a section of the trail....



...exactly.

Onwards and upwards though, despite a locked and electrified deer fence which forced a pretty gymnastic approach to getting me and a bike through the opening above a 7 foot gate.



After a quick lunch i headed east from rannoch station for the start of the trail up past beinn pharlagain and then cutting slightly west to loch ossian. The warrior poet looked on as i struggled with the evidence of the recent passage of motorcycles. The land here is wet and boggy: clearly some sort of race had passed and the trail in places was 30+feet wide, 4-6 feet deep and basically in tatters. i doubt i rode for more than 10 meters before having to get off for another clamber and foot soaking...



I doubt ive ever seen a trail so summarily destroyed. A real downer.

Still the view over to the north side of the aonach eagach was spectacular.



From there to loch treig left me looking for small stones to put in my ears to drown the noise of the headwind. That at least made the decision to get off the bike again and push up into the feith chiafain easy. I might be pushing up improbably steep and broken trail, but at least there was peace!. Again the passage of motor cycles was evident. The trail had been beaten up, with loose rocks a foot in diameter littering the trail and many gouged, deep trenches cut by motorised passage. Where the trail was rutted, they had simply passed by, usually above on the hill side, knocking all sorts of crap onto the trail and making what is usually a technical challenge, a brutal episode. Some sections (like the one below) were relatively unscathed, and its a real pleasure riding high mountain singletrack.



After crashing over the bars, and pinning myself face down in a river momentarily (jones bars and the top tube make a great ankle catcher) i made it back onto the west highland way. I had been hoping to drop down the blackwater descent to kinlochleven, but i was already 9+ hours in and i had been out of water for over an hour. That would add an hour of down, and a chunk more of up. I couldnt afford any more altitude loss, so back up and over to the devils staircase (another wade classic!).



Again, the buachaille revived me and i dropped rapidly down to a pint of lemonade and a half of beer at the kingshouse before tackling white corries out of glencoe. The staircase has been given a new coat of gravel - the sure brakes and sorted geometry of the bike allowed me to really punch it on this section of track. Slowly, im getting used to the speed and coping with the ragged nature of this sort of riding.

Engaging the fast gears allowed me to skip over wade's road back to bridge of orchy and then in failing light, i decided to take the road and dropped down to tyndrum and then to dalrigh. 11 hours 58 minutes. I wouldnt say it was pleasant but it was definitely a test of mettle.

Then all i had to contend with was the fact that i was running on vapours, and they had closed the A82 road to glasgow....though of course the sign said delays expected, so i did a lot of needless miles before getting home at 1am thoroughly foobared.

A long time ago, in a galaxy far, far away....




We used to race 24 hour races....

Generally we used to have some sort of vague theme going.

The white overalls rocked....still have em somewhere....for more see naegears.

We were young and our bodies could take the punishment: beers every lap, an almost entirely meat based diet...and a week of recovery.....

Its the 24 solo champs this weekend....friends grant3, jac, Mr Makin and various others are racing. I grew tired of zipping around in tiny circles a few years ago, but part of me wishes i was there....

Heres the 'trailer'....i'll be interested to see how they get on. Newcastleton isnt the uk-typical farmers field course...

I love it...

I love watching the skilled riders when its tough conditions....amazing skills..

Ae Avalanche Enduro mucking about from robert hamilton-smith on Vimeo.

Monday, May 10, 2010

Wait...

What do you think of this then?

Accepting for a second the observers validity, thats pretty cool. It might help me shed some more kilos and finally duck under 90kg...

In saying that, tonights Yucatan style chicken (sit chicken in a mix of grapefruit/orange juice with lots of garlic, some cloves, a bit of cinnamon, some achiote some chipotle en adobe and black pepper - fry) with corn tortillas and bits&bobs is no way to stay svelte.

But i reckon i deserve it. This weekend burned some calories for sure...the Ae Avalanche Enduro. Format: friday and saturday course opens for practice. Basically it consists of select parts of the big loop and 'the shredder' one of the downhill runs there. You have a generous amount of time to make it between the timed sections where you race 2 up. Your compatriot is found by doing a seeding run on the saturday afternoon, after practice.



The timed sections are not long - about 3-6 mins....but some are pretty balls-out hard efforts. A lot of fuss is made of stage 4 (of 6) that includes a (gasp!) climb. But for me, stage 6 is the issue - the shredder. i can get down it, and indeed do the jumps on it courtesy of the new bike (well all except the road gap, but that is taken out of the race after a bloke rips half his face off) but i cannot descend it anywhere near in control at race pace.

Saturdays practice (which takes me 3 or so hours) is useful. I'm getting to know the Vertigo, and to be honest i'm pretty overwhelmed by what this bike can and will allow me to do. It is best on hard & fast mountain terrain, rather than table tops and ultra rough dh type terrain, but the limit is definitely the pilot. I crash in qualifying on one of the '7 stanes-typical no edge (tm) corners on loose stones', then again trying to take a poor line on a slimey fresh cut drop in - much to the baying crowds enjoyment.

In the end, i'm top hardtail (though there are precious few) in 74th. Top 25% is good for me. My friend Rob Hamilton Smith smashes into the top 20 and Nico Vouiloz is in 7th ( i think) after on-sighting the seeding run...yep. No practice...amazingly fluid rider....and fellow Moulineer Lyndsey is right up there in the dames (the race organisers term, not mine!).



Race day after an early start: My fellow rider is Stuart Bond - a good bloke. A veteren of several Avalanche and mash up type events, he is really helpful keeping me right. We decide (as many other pairs do - due to the narrow tracks and lack of passing opportunities) to take it turn and about for leading into the sections. We have good banter and are pretty evenly matched, though i use the xc fitness and hardtail to my advantage on stage 4.



On stage 5, stuart has the lead. Unbeknownst to him, i launch off a steep transition on one of the table top jumps. These seem to be more bmx suited than mtb to my mind and many others, and they are pretty unpleasant if you dont soak them up. Needless to say i am skywards and over rotating before i touch down off course heading down a fortunately grassy slope over the course tape and into a small gully. Regaining the course gives me a lot of work to do, but i come in a second or 2 down on Stuart with only the Shredder to come. It is my turn to lead, but i gladly hand this over and Stuart dissappears off nto the distance. A poor line choice loses me more time and my nerves start to jangle as i hit some of the bumps too fast and ragged. Into the final drop on Omega man trail and there is a crowd. At some point i have picked up a puncture and the rear end is fishtailing as i try to soak up the drops. Onto the ladder trail with a last minute adrenalin kick as my completely flat rear tyre refuses to steer me off the end without a caveman effort to keep from flying face first into the brush.



I lost some time on that last stage (probably close to 30 seconds) but that was to be expected. Even so, i made it into 58th place - which i'm pretty pleased with. Next time i need some burlier tyres (stiffer sidewalls really) and some bigger cojones. Lyndsey did really well (i'm sure she will post something soon) and Rob punched it into 13th on a borrowed bike. Given the calibre of the field that is a pretty impressive result!.



Some guy called Nico won, and i'm sure he'll go onto great things.

Good fun indeed.

Garda

So we were talking about Lake Garda the other night. I'm not sure this vid shows the best riding there, but it aint bad...

Lake Garda Springtime Riding from Marco Toniolo on Vimeo.

5 speed.

I've been playing around trying to get a system sorted to remove material from the non drive side end of the alloy carrier in shimano cassettes. A lathe would do it, but i dont have access to a lathe - yet!

It struck me that using commonly available and cheap facing tools may work. After all the material is soft aluminium.

After messing about today trying to centre and keep the cassette level, i think i have a system sorted.



The end results are not perfect, but WAy better than using the end mill in a pillar drill and a dremel with a grinding head.



It would have been neater but my first iteration (see flickr for more) didnt keep the cassette level. Oh well.

Unfortunately the alloy carrier design for the slx and ultegra 9 speed (cs6500 series) cassettes has the spokes that actually carry the cogs protrude from the inboard end of the alloy carrier, which limits the amount of material you can remove. The xt (m770) have an alloy carrier that allows a lot more material to be removed from the back, meaning it can be snugged much further inboard, and allowing 6 (maybe 7? see walt works...) speeds to be fitted with 9 speed spacing.

However, with a bit more work i would have a very passable 5 speed with a good range, say: 15-18-21-24-27 as an alternative to the 17 - 34 of the 6 speed xt or perhaps i could use the M770 18-21-24-28-32 with a 15 or 16 king cog.



Why all the fuss? options! The jones may very well go 5 or 6 speed at some point and i am limited to a 34 tooth middle ring maximum unless i use a double front set up, or am willing to put up with a rubbish chainline. It also gives me options for the Vertigo.

Also its fun...there we go.

As Hannibal would say....

"Nica, B.A!"

Genuine Innovations.

Jimbo had mentioned this pump while we were over at the end of last year. I am counting the days...GI stuff works so well...

[video from mtbr.]

See Otter?

Not a typo...see?

Heh! ...anyway...what have i been liking at Sea Otter? Apart from Team Giant's kelli and carl taking the wins in the super D, the edge stuff is sweet. Tubular 29er rims at 290g each. Road wheelsets at just under a kg and a few wheels laced to industry nine hubs/spokes.



All good stuff. I want them to make a fork with a tapered steerer, though DT's new offering at mid 500g looks to join the niner fork in being hard to beat for the rigid/xc dream build.



Shimano's 10 speed - dyna sys: well it makes sense. The video below from pinkbike is worth a watch.



IF's lefty/bb30 bike is beautiful - as you might imagine.



Rock shox not only have a rumoured 140mm 29er fork, but a neat guide for hydro cables to route through the head tube. You know, for when you bust out a tail whip off that gap jump.



Remarkably simple...



Updated: rockshox 140mm reba for 29" wheels. [pic from 2TurnersNotEnough.]



Things ive scratched my chin over have included Crank Bros who continue to confound conventional wisdom by producing a stem that has not one but two wedges - one for bar, one for steerer. It will be interesting to see if it gets the ok to use on carbon steerers, and if the tolerances are up to scratch. My guess is they wont be and we're going to see the same story as with the pedals and droppable seat posts: frequent breakages and rebuilds.



[pic from bikerumor.]

Talking of which Kind shocks have some new droppable seat posts - even one in 27.2mm diameter - which as singletrack world point out, is achieved by moving the gubbins out of the post itself.



Though the larger diameter looks better.



Rumours abound of a Rockshox and an x-fusion seat post dropper....

More as it strikes me....

Things...

Things i'm liking....



Things i'm not....

Logically not-awesome.

Vulcan (Latin: Vulcanus), aka Mulciber, is the god of beneficial and hindering fire. A damn great big volcano in Iceland erupted. This sent a plume of 'stuff' into the atmosphere, which headed south easterly, towards the UK. Problem for me was that at about this time i was supposed to be on my way to Sea Otter, aboard a metal tube that doesnt like to navigate in glass, ash and sulphur particles.

Not so fast, boyo.

Despite the fact that communication between BA and me has been, well, sketchy, i now know that all planes due to leave Heathrow until 1pm are borked. Mine was due to leave at 11.30 (ignoring the fact that the flight from Scotland at quarter past oatcake in the morning was long gone, forcing me into a 6 hour 35 minimum drive overnight).

Its a bummer. I'm still getting up in 3 and a half hours to see if the flight i was on is being delayed, rather than cancelled. If so, i need to hot foot it to London and get on that flight. But something tells me this race is run. Which is a crying shame.

Anyway...it ain't over until the fat lady sings, or the Vulcan spins...

Easton haven carbon wheels.


Pretty interesting...read about them on cycling news...which is where i lifted the pic from....

Phil Wood.

There are certain things that will live with you forever. If you have a Phil Wood product, especially a hub, *that* is one of those things.

Pulled from Bicycle Retailer.

Phil Wood, the man responsible for sealed hubs and bottom brackets, died on March 14 at his daughter's home in Roseville, California. He was 83.

He started the Phil Wood Company in 1971 as primarily a hub maker, though he offered other components. He sold the business to Peter Enright and a group of investors in 1991.

“I feel so lucky to have talked with him about a week before he passed away, and he mentioned again that he was so lucky to sell the business when he did,” said Enright, Phil Wood Company’s president.

“We talked off and on over the years, usually to catch up on news about his friends in the bike business. But he was quite happy to return to the farm after selling the business to help raise his granddaughter,” Enright added.

Wood was a problem-solver working at Food Machinery Corporation. Had he not been bothered chasing bearings for a hub he was rebuilding for his daughter, sealed-bearing hubs might have taken years to hit the bike market, Enright noted.

“He was complaining to Spence Wolf about why no one offered a sealed bearing hub and Wolf told him to make his own hub. A little while later he asked Spence how many he should make. It took Spence a bit to remember what he was talking about. He said make 50 hubs and the business was launched,” Enright said.

Wood’s family is deciding on funeral arrangements at this time.

“I’m glad he and I were able to have that last chat. He was a little bothered he wasn’t as ambulatory as he once was but he was content to move on,” Enright said.

A memorial service for Phil and his wife, Vada, who passed away December 18, 2009, will be held on April 17, at the Calgary Baptist Church in Los Gatos, California, at 11:00 a.m. Phil is survived by his six children.


Phil Wood: rest in peace.

6 speeds.



(image credit: http://aroundtheedges.wordpress.com/)

Nope i'm not going to tell you how Sir Chris Hoy rampaged in the keirin tonight. 10th world championship! Awesome power - watching him kick then kick again to come round for the lead and then power on the gas for the win got me pretty damn goose pimply, i can tell you...

Anyway: 6 speeds...i've been reading around what folk have tried and it all seems pretty system dependent. We dont know how the 17-34 cassette is going to go on the back of the Vertigo just yet. the spacing has some leeway i would imagine because the spokes are so highly angled, the modded cassette can be moved in towards the middle of the wheel as well. The further away from the derailleur it is, the teeth it can cope with. This seems to be the stumbling block for some set ups. It also means you have to use lots of b-tension (which changes the arc of the top pulley compared to the cassette). Unfortunately, the more b-tension, the less smooth the shifts. There is also a minor matter of the limit screws being longer so the range of throw can be kept in check.

I want to use a saint mech, because they are tough. They are also shadow style mechs, which means they are tucked under the cassette further out of harms way but critically, closer to the cassette, decreasing their ability to cope with a 6 speed/large range set up. It is possible it aint going to like the 34 tooth low gear. Options: spacing the deraileur out from the drop out, sometimes by as little as 2mm can be useful apparently. Im not sure what i think about that...yet!

I could also drop the 17-34 modified cassette. The reason i am using that spread is primarily because it comes on an alloy carrier. The singlespeed cassette body of DT hubs is aluminium and individual thin steel cogs will chew it up for breakfast.

Other options. Use 18-32 xt cassette part. i drop a gear ratio, and get less useable range, but the 32 low gear may work. The xtr cassettes come on carriers and could give a similar range, but no real benefit over xt there.

I could also use a road cassette: in looking at the older style 9 speed ultegra 6700 i can use the two low gear parts - 21-24-27 on an alloy carrier and 17-19 pinned together. Then, because the pinned together bits dont have a spacer attached, (see the tech docs) a chris king cog should nudge up along side very nicely, maybe with a judicious 1mm spacer, to give me 15-27 6 speed. With the large range widget in place on the saint mech i reckon if the 17-34 doesnt work, this will. Only issue - the teeth on the 15 tooth king are likely to be a little taller, so the shifting onto and off may not be hugely crisp, we'll see if it is needed.

In that scenario, the gear development would change only very slightly if i use a 36 tooth ring. It is possible that this would allow me to put the ring in the middle position also - which MAY be better for chainline...we'll see.

With 36 tooth c'ring and 15-27 i get 121.5 to 218.7 development versus
with 40 tooth c'ring and 17-34 i get 107.2 to 214.4.

I could also use 35 or 34 if i needed more climbing gear.

Given the gear i run on the singlespeed (33-19) gives a development of 158.2 im pretty happy with this range.

Damn. My brain might have just cramped.

So once again, here is Hoy, on the BBC winning his 10th (!) world title...

Veracity.



(image from velovert - a good french mtb magazine.)

This is going to be the first in an irregular series of thoughts on the thing that seems to be most lacking in the cycling press - both magazine and online - these days. Veracity.

One could arguably quip that this is a hobby and therefore the pursuit of the truth could be considered over extension. But i'd disagree. Look at the average age and wealth of the average cycling media user. It is the responsibility of the media to try (at least a little) to avoid dumbing down this 'hobby'.

Why? well for one, misinformation can lead you into some pretty dark places if you get used to it. I wont go off on a rant about the state of world politics, health or personal relationships - but i dont think you'd have to ponder too long to come up with an example of how misinformation led to a malodorous conclusion for you recently.

But it's a hobby right? yes. Just because it is a hobby doesnt mean there should be an omission of action to provide a reasonable level of technical accuracy. Or in the worst cases a commission of effort to mislead.

Enough with the lecture. If you want more and a much more considered opinion, id recommend cozy beehive.

So for this first effort we have MBUK: a test of the Commencal absolut titanium 4x. A pretty cool bike, developed for a pretty cool rider. Yes MBUK is aimed at a younger audience than most, but why not get them early? get them interested in actual mechanical principles and engineering rather than ridiculous photo angles and odd haircuts?.

To quote the review: "The entire frame has a special bead blasted finish that helps to increase both stiffness and overall strength."

I'm not sure where this claim comes from: a cosmetic finish adding to the strength and stiffness? i get the feeling that somewhere along the line there is an assumption that bead blasting confers some form of mechanical advantage in the way ball burnishing can. Either that, or the writer is mistaken and the frame is not bead blasted but ball burnished (or shot peened). The commencal website doesn't have any information obviously available, and i could find nothing on the web to clarify matters. So why did the reviewer say that?

I'm going to copy and paste a section from the independent fabrication website that will give some further information regarding this. This will be at the bottom of this blog entry. Bear in mind that most ti bike manufacturers are notoriously opinionated about the benefits versus harm of any surface treatment of ti tubing. Seven cycles have a retort on their website.

There you have it...or dont as the case may be.

Shot Peening? Why Do We Do It?
Shot peening has 4 major benefits in the crafting of titanium bicycle frames:

Fatigue life is enhanced significantly increasing the useful life of the frame
The frame is stress relieved so that all of the component parts work together
Surface hardness is enhanced increasing resistance to scratches
Provides an aesthetically pleasing finish
Shot peening is a cold working process in which the frame is bombarded with small spherical metal balls called shot at a precise angle. Shot act like tiny ball peen hammers and create a uniform dimpled texture on the surface of the frame. This compacts the outer layer of the material.

The processes of butting and welding titanium tubes to make a bike frame are known to create tensile stresses in the frame material. Tensile stresses make the area in question want to pull itself apart. This is a bad property to impart to a bicycle frame as any minor notch or micro crack in the frame will want to propagate and further compromise the material. The induced tensile stresses are most concentrated in the heat affected zone — the area of the welds. Thus, strength is compromised precisely where you would like it to be greatest.

Shot peening of a welded titanium joint substantially increases both fatigue strength and fatigue life as compared to the same joint which is not shot peened. Shot peening imparts what is called residual compressive stress which counteracts the residual tensile stress, which is created in the process of cutting, grinding and welding. Typically, fatigue strength of a welded titanium joint after shot peening is double that without shot peening. Fatigue life is enhanced by shot peening to an even greater degree.

By shot peening the frame after it is welded together, we are able to relieve the stresses in the material providing compressive qualities, which are known to reduce micro cracking and enhance fatigue life. Without stress relieving, each of the tubes will retain tensile stresses which tend to conflict with one another. Stress relieving allows the component tubes of the frame to work together as designed, acting as a unified structure rather than a collection of competing parts.

The shot peening process work hardens the surface of the tube, while giving it a finely textured surface. These two properties together create an attractive finish that is highly resistant to scratches. If scratched, the scratch is harder to see because the surface is textured. The textured surface glitters in the sun in a manner similar to that of a pearl paint job.

Some people may confuse shot peening with sand blasting or bead blasting. At IF, we use sand blasting on our steel frames to remove contaminants. We also use it impart a microscopic tooth to the surface of the metal to provide a mechanical bond with the paint. Bead blasting is used for cosmetic purposes to provide a uniform finish to the surface of the metal. Neither sand blasting nor bead blasting improve the mechanical properties of the metal.

Shot peening is used precisely because it improves the performance characteristics of the finished parts. It is used in the aerospace industry, in high performance cars and motorcycles, and in light weight bicycle stems and bars where light weight and high strength are performance imperatives.

What's the big deal? Don't a lot of frame builders shot peen their frames?
To the best of our knowledge we are the only titanium frame builder using the shot peening process. This process should not be confused with bead blasting, which is used to provide a cosmetic finish to ti bikes. Any company that claims to bead blast over a shot peened finish does not understand shot peening. Any type of finish polishing brushing or bead blasting applied after shot peening negates the benefits of shot peening.

See www.shotpeening.com for more info.

Who does the shot peening of IF frames?
We do not do the shot peening in house. We use Metal Improvement Company in Wakefield, MA, which specializes in shot peening high performance parts for the aerospace industry. At Metal Improvement our frames are peened along side of parts for the space shuttle and F14 jet engine rotors.

See www.metalimprovement.com for more info.

Why can't IF do its own shot peening?
To shot peen properly requires the use of very large, sophisticated, and expensive computer-controlled equipment, and trained personel. Shot Peening really is high-tech stuff, and it's tough to get right. We decided to leave it to the specialists. In addition, we are confident in the established leadership, reputation, and quality of Metal Improvement.

Someone told me that shot peening can tear the metal if the angle of attack is less than 85 degrees. Is that true?
No.

The shot peening flow at less than 85 degrees is known as overspray. This neither helps nor hurts the frame surface. It does nothing to a previously unimpacted surface and it does not detract from a previously impacted surface.

Why did IF decide to use shot peening on their Titanimum frames?
The primary reasons are that we are pleased with the mechanical properties we achieve with shot peening and we are delighted with the lustrous finish. The finish beautifully matches the painted panels we apply to our frames which often have pearl or metallic qualities, and it makes the frame stronger in the process. Another important reason is that we were not happy with the established ways of finishing ti frames. While these are less expensive, brush and polish finishes are purely cosmetic. In addition, applying those finishes is a dirty and possibly unhealthy job which no one enjoys doing.

Why not give the customer a choice in finishes?
While we considered offering bead blasting, brushed and polished finishes as alternatives, we became so convinced of the mechanical and cosmetic merits of shot peening that we concluded anything else would be offering less than the best.

Unfortunately, it is not possible to both shot peen and have final finishes employing these other methods. Shot peening must be the final finish with the exception of paint, as bead blasting, brushing, or polishing would destroy the mechanical benefits of shot peening.

Self harm.

So a report on radio 4 this morning suggested that the incidence of self harm hospitalisations had increased by 50% over the last 2 years. Conveniently, it never mentioned whether the ACTUAL incidence of self harm had increased - just that more people were going to hospital. Still its not good. Why would people want to harm themselves?

In the same program mention was made of a new gallic phenomenon - the French youth - some as young as 12 years old - taking up 'Le Binge' drinking. Copying the UK?

Why are the youth so visibly disaffected? Could it be (as reported)the growing number of websites looking at self harm with (gasp!) pictures and real life stories?

Lets look at the rest of the news this morning. The brutality of the killing in Nigeria. Biden (with no clear self consciousness) calling for the Palestinians and Israel to re-enter talks even as Israel plans and builds more housing in the occupied territories - despite impotent international condemnation. The refusal of the saintly Obama to recognise the 1915 Armenian Genocide (do you read robert fisk in the independent? you should - heres a quote thats worth chewing on "Perhaps it's worth remembering that in 1939, Hitler asked his generals – before setting off into Poland to murder the millions of Jews in eastern Europe – a simple question: "Who now remembers the Armenians?" Well, Hitler got the answer he would have wanted from Obama this week.")

What else? The collapse of modern banking? The ruination of pensions? The lying and stealing of British politicians all to make a quick buck. Teachers who are members of the BNP and angelic Mark Owen admitting to at least 10 affairs despite having married the only woman for him. OMG - OMG!

So these young people who are drinking and fighting and hurting themselves - truly, is it ANY wonder?

What do they have to aspire to? The readily accessible stream of information and bullshit shows them, quite plainly, that no matter how hard they try the odds are high that their future holds nothing but financial worry, dishonesty and unhappiness. Perchance to dream...just as for Hamlet....where can one find the truth that justifies our actions?

I truly dont know the answer to that question. I dont think i ever will.

Burn those beards....

Someone needs to invent a nose plug.

First century of the year today, and apart from numerous mechanical issues - of which more later - my nose dribbled the whole damned time....

100miles. 6.5 hours. Tak me doon climb (ouchy) and some sketchy traffic in Airdrie on the way back....

It feels sore, but good to have turned circles for a while...but fitness is still a ways off.

Headset solution: xx 44mm trad.

This post has had to wait for me to have a little time to type it all up. Recently, i decided that my riding had become a little too limited. Singlespeed or fixed: rigid. All the time. No matter the distance or terrain. At first it was both interesting and enjoyable. A challenge to ride fast or far over sometimes difficult terrain with the simplest of bikes. But after several conversations with the chops optional and dan "damn he's fast" darwood, i began to question whether i was too *used* to travelling at a certain speed. The point was made that your vision for riding can be changed - you can get used to going faster. Sounds simple, and i kind of thought that maybe it would pull me out of the rut i had found myself in. I have also become a little bored with the diet of endurance races. There was a time when i rode cross country races, too. Yes i was a younger chap then, and i didnt have so much mass to move, but i used to quite enjoy it. i was also getting jaded watching the clock and the odometer, rather than the terrain and the view. i wasnt riding for enjoyment.

So i made a decision to buy a road bike, so i could more easily 'train' over distance, using power, and heart rate to see how i was going. In addition, i would ride my mountain bikes for (gasp!) fun! try to head places where i could ride in the woods, on technical terrain over rocks and roots. I also decided to explore the options of getting a geared, suspension type bike. With that, i would learn to read terrain differently and mix up the riding more. Perhaps even enter some enduro/megavalanche type races.

A few months of thinking, reading and asking questions. My initial thoughts were based around a full suspension 29er bike. I am so used to the bigger wheels now, that 26" just looks and feels weird. The options were somewhat limited - fisher rumblefish, superfly 100 (which is a little racier), intense tracer 29, turner sultan, or the one i was tending towards, santa cruz tall boy.

Then i got to thinking. Those were all a LOT of bike. They were going to be a big change: they also had shortcomings - for me at least. Geometry, material, components etc. i began to think i was perhaps a year or so ahead of myself. What i really needed was a hardtail. Ease myself into the whole gears and suspension thing. I havent ridden a geared bike for 10 years!

The canfield bros nimble 9 and the banshee bikes paradox were looking like just the ticket. Stout, and built for 120mm travel forks.

About 5 minutes after convincing myself to wait for the nimble 9 to appear, i started seeing all the things i didnt like. Material (steel is less scotland proof than ti) again, geometry (it could be lower, and slacker) blah blah blah. The other thing that just didnt cut it for me was the fact i couldnt run a tapered steerer. These are de rigeur as far as i am concerned for longer travel 29er forks. Bam! i remembered a thread where a custom frame builder had mooted a new headset solution, that would allow an aesthetically attractive way to fit a tapered steerer fork to a headtube designed for the zero stack/inset standard.



I rememebered seeing some of his other builds and decided to drop a mail, you know, just to see if it would be an option. Some of my other thoughts had centered around the tech being used in snow and downhill bikes: wider hubs and bb, offset seat tubes to allow shorter stays and more.

So i got in contact with sean chaney of vertigo cycles. With the speed of thought the frame was blue printed, and the components to be used sorted out. The head set was still embryonic, but the idea was clearly excellent. Singlehandedly, sean has created what i consider to be the most versatile headset system in the industry. i felt it was only a matter of time before it was picked up by a large component maker. I think sean thought it might take an actual bike to show people. My bike-to-be and a similar bike sean is going to make for himself were going to be the working prototypes. The lower cup was going to be made as part of a small run by a machine shop and the upper was going to be a slightly modified zero stack or inset.

Then cane creek became involved and all of a sudden it is a reality. Dubbed xx44mm traditional.





Hold on! i hear you say, dont we already have a 1.5" headtube and headset that can do all this? Yes. But its heavy, and ugly. Fine if you want to run a lefty, but i dont. The differences may seem small but they are important. The tube is 44mm inside diameter, making the outer diameter more in keeping with modern standard tube sets than the barrel used for 1.5". The upper bearing is fitted inside the steerer tube, giving clean lines, and minimal weight. The lower is an external cup with a 1.5" standard bearing, but a cup skirt to fit the 44mm headtube. Anything from a ~75mm length headtube and longer can be used, with any of the currently available (more on this in a minute) forks. Ti tube is available, and steel will be very shortly. Aluminium wont be far behind. Simple, and sensible. As an aside, this headset also means that if you have, say, a Giant trance, you can run this headset and fit a tapered steerer fork - with all the benefits that entails. Genius.

Cane Creeks press release:


About the forks. Niner have Fox forks with limited availability, there are some OE Rebas kicking around and there are Marzocchis. Trek/fisher are using forks but dont sell them separately. Although finding forks is tricky, its not imposible, and very shortly, i suspect tapered steerer will become standard.

Thats it for now.

Things.

Things have been sort of dense lately. Packed in. A lot of stuff with not much space around the side. Weather, work, riding, all sorts of things.

Anyways. I finally blew a fuse today on the way to work. All 1/4 of a mile of the journey. I drove to work today, as i was doing house calls. The roads are something i usually skim over rather than sit 'in' but thats the beauty of a bike eh?

Three times on the way to work i was exasperated at the selfishness of drivers. Aiming for that gap, even if it means others can't pass. Or pulling out of side streets whilst forcing anohter to brake hard to avoid a collision: "sorry! but i was in a rush!". Yeah. Right.

Then of course there is the classic amber - oonot quite its red now!- gambler. All to get stopped at the next light that is 200 yards further down the street anyway.

What the hell is wrong with these people? And that does nothing to explain the turmoil in the carpark at work. People parked on the grass, half way infront of others or completely in front of others 'because im only going to be 5 minutes'. Yeah yeah yeah. To gain what? a 50 yard shorter walk to the front of the health centre. Please.

Anyway, ill stop whingeing while im only slightly less than ahead...

heres an interesting read: Bohemian cycles on bamboo.

Heres another interesting read: a considered legal opinion of 'sorry, mate i didnt see you!": its not a defence, its an indictment. This needs shouted from the rooftops.

What else?

Cane Creek to make a headset that addresses a *lot* of issues for modern frames. My opinion: This headtube/headset interface will be the optimum choice for most bikes that are ridden off road from now on.

Token NAHBS pic? a really lovely Quiring. It hits the scales at just under 20lbs and looks fast. He can build as well as he raced!

As ever, some beautiful...and odd... stuff beginning to come to your screen. I'd recommend a flickr search. From Bohemian cycles flickr, this is an ...interesting... one.

I'm liking the Vanilla cycles/Speedvagen/Pegoretticollabo track bike. Super clean.

1'15"

The leaving test from the Keirin school is to do a km in no more than 1'15". Gear must not be bigger than 49:15. Thats pretty quick...Might break out the rollers and see if i can get close....then dwell on the fact thats without wind resistance....



Keirin tracks are roughened concrete, so that they are all weather. Thats going to smart a little.

What else? personal comms have suffered in the face of work. Im training to be a trainer. Scary thought eh? Anyway, its been a pretty interesting few days up in Stirling at the coal face. I did a section on ethics teaching. Ethics being the tool with which Moral Philosophy is dissected. Ive been all logical positivist recently. The great human experiment will lead to the right and the wrong becoming apparent, not so much basing things on some old, fuzzy list of moral duties.

Collecting a few bits for the skeletor. I'm liking the campag seat tube collar. It seems that a lot of eat tube clamps focus the force over a small part of the circumference of the tube in order to grab the seat post. The idea of the offset slot and bolt is to create more circumferential spread of force. Important with a sub 1000g aluminium frame in which i will be using a shim and a ti seat post. Probably.



We had a pretty interesting discussion on aluminium nipples for wheel builds between friends recently. Amazing the polarised opinions. I don't use anything else. why would you? Calls of corrosion and splitting have never been apparent in my experience. As an insightful birthday boy (happy birthday marquis of darkness!) pointed out i dont tend to keep the same wheels in use for very long, the longest running set at present is 2 years. But that is on the town bike, that is covered in road salt, gets used 5 days from 7 at least and hasnt been washed in 12+ months. I had a look. No corrosion noticeable and retention of good spoke tension, fwiw. Maybe if my bike lived outside (rather than next to a radiator in a warm house) my experience would be different. As its not, i have no reason not to keep using aluminium nips.

Jeff has a new video up. Check it out. Yes thats his trails from his door. Yes, thats a larry, and yes it works well. I might need to invest.

Parts are being collected for the Vertigo. I am really stoked on how this is going. My only concern is that i wont be rider enough for the bike. We'll see. At present, 120mm reba with tapered steerer up front, maxle to DT 440 dt supercomps Aluminium nips (!!) to stans flow. Headset, details tba. But it will plug into a 44 i.d headtube. Thomson stem, prolly jones bars, though i might use some Groovy's. Moving back, saint crank, 40 tooth e13 ring, with mrp chainguide (thanks to Adams tinkering) and a DT 440 rear with 6 speed 17-34 block, supercomps to flow, with a saint short cage doing shifting duty.

The bike will be stopped by saint hydros - a first toe dipped into the mineral oil bath of hydros for me. ESI grips of course, and xtr pedals. Rubber tbd. Thomson seat post, Selle san marco Zoncolan saddle.

It will rip. Its rider will bleed.

I'm still reading through Robert Fsk's book Pity the Nation (thanks Anja). It is an incredible, mind blowing, harrowing and enlightening read about the history of Lebanon, in particular the 1982 invasion by Israel. Massacres, infightoing, politics at its worst and war crimes. I was 9 when this was firing off. I do pity the nation. Israel, not so much.

Lastly, my sock guy socks arrived. The post office have been insanely incompetent. These socks were ordered to arrive for christmas. They were lost and more sent (thanks sock guy) and after 10 days of harassing the post office they finally delivered them today. Assholes. Good socks tho'.



Still, the sun is shining. I'm joining davechopsoptional for a farewell from Alpine bikes ride tomorrow. All is pretty good.

Bike fit.

I have just bought a new road frame. Yes, i only got the cannondale caad 8 a few months ago, but i knew at the time that it was very much a 'starter' road bike, and that if i liked riding the road, i'd want something perhaps a little tidier.

So a Spooky skeletor is coming my way. Anodised black, size 54 with compact geometry and an aluminium frame. Should be sweet. It's well priced and has garnered good reviews in terms of the ride quality. Initially i'll swap parts over, but there may need to be one or two changes. The tourery triple will be removed: i spend most of the time in the big ring, and no time so far in the granny, so a 53 on a standard double will be welcome. I'm going to use a shimano 105 - it is not high zoot, but it is very much more pleasing on the eye than the truvativ i have at present.

The wheels, at present will be an old dt 340 to dt R1.1, with the rear an as-yet-to be-decided-on build, most likely with the new version of the R1.1 - the R415. At present, the choice is between a DT 340, or a shimano 105 for less cash. We'll see.

The rest is getting swapped over from the cannondale. Maybe a different stem, and most certainly a different seat post. It's a shame that it wont be blacked out, but as time goes by i'll work on it. These are not mine, but they are close to what i'm going to aim for.





A few folk have commented on the fact that my road frame seems small for my 5'11" height. Yes and no. I tried out a few bikes, and different sized frames, prior to getting the canondale. As im getting more used to road riding, my ability to stretch out is improving, and i'm happier with the lower bars. Just took some time to get used to. Initially, i removed the stock anatomic bars in favour of some short reach and drop compact bars. Recently i have moved to a slightly longer stem, in order to get the front rear balance better, and the flats further away for seated climbing. The saddle was initially rammed forward, and i was considering an inline post, but gradually it has come back by about 4mm. The top tube on the spooky is 4mm shorter, and i will prefer the saddle being further back relative to the bottom bracket i think, so this is all good.

But again - its a small frame no?

I had heard about the bike fit system available on the Competitive Cyclist website through some chat on a bike forum. You need to be careful using a bike fit system, as individuals are never entirely equivalent. Fit is best done by either informed trial and error, or by a professional. On a mountain bike, i'm pretty clear about what fits. For road riding, where so much time is spent sat down, fit is both more important and new to me. However, i got to a point with the canondale where i was pretty certain what reach i needed. The other aspects of road riding fit that are particularly important are balance of weight between the wheels and steering weight distribution. Too short a stem or too high bars (or rarely funky geometry of the fork/head angle) can leave the front wheel grasping for traction on fast downhills. A short wheel base with good front centre will help the bikes handling and paying attention to reach and saddle set back will allow the legs and glutes to help the core in keeping the trunk low for wind resistance avoidance. Of course, you also want to avoid a numb wee man if you can.

So: as long as the frame is designed well, and your fit avoids overly pushed back/forward bars and saddle, it should be good.

My Measurements

Inseam 82 cm
Trunk 66 cm
Forearm 34 cm
Arm 60 cm
Thigh 60 cm
Lower Leg 55 cm
Sternal Notch 151 cm
Total Body Height 180 cm

Plugging my measurements into the Competitive Cyclist fit calculator was interesting, as it confirmed what trial and error had suggested to me - despite my height, i will fit best on 54cm top tube skeletor. It also suggests that at least according to some folk, my current ride position is reasonable.


The Competitive Fit

Seat tube range c-c 53.1 - 53.6

Stem Length 10.0 - 10.6
BB-Saddle Position 70.9 - 72.9
Saddle-Handlebar5 4.3 - 54.9
Saddle Setback 5.1 - 5.5


Here, the Eddy fit (as in Merckx) is a slightly old school fit, higher front end and further back. The French fit is more of a touring type set up - higher again at the bar, and further back.

I suppose i'm probably aiming for a racing type set up for what i want to do on the bike - high output, mid-length rides with lots of climbing.

Once its built up and i've put a few hundred miles on it, we'll see if all that tape measure work paid off.

If you want to give it a bash, the fit calculator is here.

Red Breast.

Where have i been? Well, for starters - in London town visiting Gfunk and Hfunk. We had a top time, mostly food orientated but with a little culture thrown into the mix too. For starters we went to Terroirs, a very fine wine bar/restaurant where the wine is both unusual and beautiful. 100% Malbec was the order of the night, and we were joined by gerardfunk - it was great to see him also.



We made it to Moro, where yet again we enjoyed an amazing meal and fine food.

Next day we mooched at the Tate modern, then enjoyed an amazing stew and much mirth. An attempt at non-eating fun was made when we met the horse and made our way (via a dousing on the wet roads) to the Portrait Gallery to take in some views of some influential people. Yes the ballet dancer was ...



...average, the blood-head a bit strange, but the photography in particular was ace. On the way we did some bike spotting. Odd bikes.



Next stop was Soho for some veggie fun at Mildred's to round out the evening.

After waiting forever, the Van Gogh's letters opened a new view on the prolific painter for me. I particularly liked the sketches he sent in letters to his brother Theo. A shame he ended it all by shooting himself in the chest - a brilliant and dedicated man indeed.

It was good to be back in Glasgow to see the P phone, though the robin we found cowering in the kitchen this morning reinforced the feeling that her hunting prowess is improving. Some how, despite heavy loss of feathers and a few bats around the kitchen as the 'phone was pacified, seemed to leave it only a little the worse for wear, and it flew off after catching its breath on the window sill.

Happy days.
