So I went for a ride today, hit a few twisties and on a straight stretch cruising along I felt the back wheel veer off to one side. I thought I had a puncture in the rear, pulled over checked pressure, all good. I rode a mile or so more and it was freaking me out, so I pulled over again and rode around parking lot without my helmet on to see/hear anything of distinction. I for sure heard what I thought was a chain link that was crimped. i take another look and I see a piece of rubber from a seal
