I've currently got Juicy 5 brakes on my bike, and I was wondering what needs to be done to swap to a 185mm front rotor besides the rotor itself. Will I need a new mounting bracket for the caliper? My current rotor is also slightly not true, so a new rotor would also help alleviate this problem. I ride where there are a bunch of hills, and the fronts heat up quickly. I'm 200lbs on a Windsor Pro 29er.
