I saw this thread a while back and ignored it cuz I've seen the bike in the store; it was too small for me )I guess they come in different sizes) and something about my little test ride down the isle made me run away. I don't remember what it was, I don't think it was the twist shifters. Anyway, I'm glad someone is enjoying this bike and holding their own against the barrage of nay-sayers.
Anyway I heard your experience with long stem Schrader valves and I recently purchase some valve extenders from a local auto parts store for an aero wheel of mine. I haven't used them yet but you might like to have one on hand ...?
