I purchased my 08 Rockhopper Disc about 5 months ago and having been riding it 2 - 4 times a week. I have brought it back to the LBS approximately 4 - 5 times because the rotors appear to be out of true. I can hear the rotor hitting the brake pad and making an annoying ticking sound. If I spin the wheel and watch the rotor pass thru the caliper I can definitely see a wobble on the rotor and hear a noise when the rotor his the brake pad.
The last time I was at the LBS for this issue they took the bike for a couple of days to test ride it and adjust the brakes once again. When I picked it up the mechanic told me that he adjusted them the best he could and they are now working great. He also stated that the rotors are within tolerance. But if I continue to have an issue the I will have to upgrade to BB7's.
Now I trust my LBS but is it possible the BB5's cannot be adjusted properly and the BB7's would make a difference?
