i have a computer, the same one i have for all my bikes. makes me want to get a gps system for geek points.
anyway, yeah. thanks for the offer on the 14. good to have options. i hit sheldon brown's gear calculator last night, and found the 42/15 would be ~7o gi, which would be interesting for the spin. i'm gonna give that a shot. do you carry a chain-whip and a lockring tool with you wherever you go?
