My backup bike, (since i didnt wanna spend much on a backup bike that i only use 1-2 times a week), is a trek 4300. Everythings stock including rims except for the duke fork, shimano xt derailleur and the crankset. 1-2 times a week i take it off 3-7 foot drop offs. The matrix 750 rims have not lost their shape at all. Theyve stood up to the same beating my rhynolites have taken, is this just plain out luck? Or are they pretty cheap tough rims?
(I was under the impression they were extremly bad when i bought the bike.)
