Hello all, I just purchased a used P5 and am trying to put my Red 22 Quarq gxp on it. However with enduro cups, the spider scores the frame at the chain stay. my lbs is going to try the rotor 4624/22 but they don't think that will give enough clearance either. is Red 22 gxp not compatible with P5? I have read this whole thread and didn't see anything that dealt specifically with a red 22 quarq. thanks!
