i need more gears - how?
im finding that the fitter i get the less im using the lower gears. in fact i cant remember the last time i came off the wee ring. more importantly im also finding that the highest gear isnt "powerful" enough. so how do i get more high gears? do i have to relace the whole shebang: chain, chain rings, and stuff. or is there somthing i can tweek?
