Lil Pixel, I can't wait to see what the current project will look like when it's done! Your mock-up is wicked-cool! (Sorry didn't read the entire thread--not sure if the brake-bridge grind is in direction of putting 26" wheels on it--?)

On the subj of touring on the twenty, I'm newly able to chime in as of 2 nights ago--did Critical Mass here in SF. Even in its fixie-form, was able to ride 4 hours straight on the thing! Though, granted, we didn't hit any major hills, and the ~5%-7% grades we did hit were all during the 2nd half when I was well-warmed up. 5 hours total, maybe not touring level, but surprised myself given constant maneuvering while clicked-into pedals among at least 500 other cyclists. Maybe lots more--the great weather brought everyone out. I didn't see any other 20s or fixie folders, but counted 20 other folders, incl Katherine R on her pink Bike Friday.
