I've seen this before. Usually it is from braking wear thinning the sidewall over time, more prevalent for people who ride in hilly or mountainous terrain and/or in rainy weather a lot. The road grit and slurry that gets on the rims forms a nice grinding pace. Sometimes the sidewall is scored by a small pebble or bit of metal that gets caught in the brake pad. And once in great a while the cause of the failure is an extrusion flaw. Glad you weren't hurt! It might be that your long braking heated the rim and caused the blowout, which took the weakened rim with it. When the rim gets really hot, the rubber of the sidewall along the bead gets hot and slippery and can lift over the rim. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
