Hey there, I have a set of 2012 Rock Shox Gold Recon on a 2012 Cannondale Flash 3 XC. I have rode them for about 5 months now. I have notice latley that there is alot of shaking in the front when I apply the brake. Took back to local bike dealer where I purchesd the bike from, and they could not figure out what the problem was. So they put a new caliber, brake pads and lower end on forks. Went and picked up today to find out its still doing the same thing. They went riding with me to see what it was doing and told me it is probably where there is a 180 mm rotor on the front and its just the bushing moving in the fork. Is this a ligit reason for the problem or are they just tired of fooling with it any advice would be helpful thanks in advance!
