P2 Tire rubbing the frame

metafizx - 2010-07-26 9:29 AM I've had the same issue.

Basically you have to make sure your quick release is set tight, with sufficient clearance of the rear tire to the frame. because on heavy loads the wheel can suck towards the frame and rub onto the frame. I had this happen to me in the beginning, and the problem's gone now that I pay attention when I put the rear wheel on.

there are adjustment screws as has been said down in the dropout, but if the wheel was pulled in by force, the screw threads might be damaged. a common problem.  these screws aren't really necessary, but they help get the wheel into position. You can manually position the wheel further out on the dropout, but make sure the wheel is lined up with the frame.

cervelo told me that you have to use the correct profile tire, otherwise there might be a problem with the clearance.  they suggested longer adjustment screws in the dropouts.

for example Continental tires have a somewhat higher profile which is technically out of spec with cervelo P2c (I don't know about the others). I use the Continentals but make sure the wheel is set back enough so it doesn't rub. I have longer screws in the dropouts to compensate.
