Well like the title says i'm only 20 but its been about six years since i was in the race scene and i'm now trying to get back into it, and wow have disc brakes hit the market...I just bought a khs team st bike witha sid race shock on it and i'm wondering how do i put discs on it...i've been told their are different versions of discs...so i need to know which ones to put on...any help would be great...also if their is a certain wheelset i should go to because of discs...thanks in advancement
