DT440, 20mm with supercomps, alloy nipples and flows. Yo. Bomber, wide and light where it counts. Disc side tension 98kgf. Variance is less than +/-4kgf. Thats pretty nice. The non-disc side is 81kgf +/-8kgf. Still within the necessary 10% for a good wheel build. Not sure why its more 'out'. Overall, pretty happy.

I'll build the rear tomorrow as we are still under snow and ice (its minus 8 degree c here) so riding is confined to the rollers.

Session 1: 15 min warm up, 30 minutes at 30kmh 180watts or so with a 30 sec interval every 10 minutes at >999watts up to 70kph (at which point a reverberation through the rollers made the floor boards hum). 'Distance' covered - 16.65km.

Session 2: 15 min warm up, then the same but ramped it up to 215 watts (i used a taller gear). 15 minute warm down. Distance (with 15 minute warm down) 22.2km.

Next i need to do some joe friel inspired 'tests'. A 6 minute max power trial, and max power achievable for varied time scales to get power zones, and a lactate threshold test. This is much easier to do with a geared road bike and rollers than a fixed gear on the road.
