The shiny cylinder on which my rear tire rests appears to have a rough spot that is chewing up my tire (little bits of black all over the floor). Not having it in front of me, I’m not even sure what model it is (I think it’s an old Cycleops). Is it possible to get a replacement part for this bit, and install it myself?
And now that my Pro Race 2 tire is really ground down, is it faster?
