I was running these belts when one of the fixed rollers came apart. Some of the balls from the bearing passed through the belt while it was running making nice little slits in the belt. The belts did not break. I replaced all the rollers and put another set of these belts on.

zOMG!! Wow, man, I'm so glad you and your bike are ok! ... and big time thanks to everyone for your support!
Thanks,
Chris
