Wasn't sure where to post this, thought this was as good as any. I have a very lightly used stationary trainer, I personally hate the thing but my work schedule is such that I have to use it for the next month or so. My problem is that it is wearing the rear tire at an alarming rate. It looks like very small specs of rubber are collecting at the bottom bracket and on the back side of the seat post. There is a flat area wearing about 1/4 inch wide down the center of the tire where it contacts the mag roller. Any suggestions?
