Today i finally had a chance to get the pinkster loaded up with the new Epic Designs bags, with an approximation of the kit ill take to the Picos de Europa. All works well. I have a few bits and bobs to do to the bike, then we are away. I serviced the rear hub mechanism, replaced front pads and bedded them in. I did notice there is a compatibility issue with the front rotor, brake and fork. The rotor is sitting too far to the left at maximum adjustment of the caliper. Still, it works. I might replace the rotor, as i want to use the alloy armed shimano rotors but we'll see. They have better braking power, are stiffer and lighter than the avids.
The packs are (predictably) amazing. Holding all the gear well without interference to my legs or the bike. They have good adjustment in order to keep everything snug. Front bag is currently holding waterproof and primaloft jackets, along with a thermarest and the bivvi sack. The rear has a wool top, sleeping bag, gas, kettle, coffee maker (thanks shaggy!) porridge and cup. I will likely re-stow stuff and put a little more in the rear, but this gives a good idea of how it will all ride. The kilo lost weight - from removing the Old Man Mountain racks - from the bike is noticeable. The bike weighs 32lb without water, so it'll be pretty light considering.
More as time allows.
