Here is my question. It was a new Cont sprinter, pumped up to 135 on a Hed trispoke whick has medal brake surfaces and tire seat. I was continually breaking going down this steep hill, feathering the rear brake often. POW it goes! When I stopped to change the tire I noticed that the wheel was HOT at the rim, quite warm honestly. I am wondring if the wheel heated up the tire to greater than its spec strength and it just popped. I was so anxious to get going, I gave the tire to a spectator and asked him to toss it for me and never did look at the tire.
Any thoughts out there?
