I want to get to the bottom of why I had a tube fail on me on Saturday. I rode my bike to my LBS to get my rear derailleur adjusted because it was still under warranty and also to take a look at some full carbon bikes. My bike was quickly adjusted and I headed back home. The ride is 10 miles each way. I recently put on some Michelin Pro Race 3's with Continental Race Lite tubes. I was extra careful to make sure that the tubes were not pinched by inflating to 1/2 capacity letting the air out etc. and I had rolled at least 100 miles on them without any issues. So when I headed out it was downhill on a rough street, but it was not that rough. At about 24mph I heard the tube burst which sounded like a gun shot. The front tire was partially off the rim and I quickly came to a stop. So quickly that I was still clipped in and fell over. For someone seeing/hearing this they probably thought I was shot. So, what does everyone think happened? Was the tube pinched the entire time? Was it just a rough road? A flaw in the tube? Were the tires over inflated? I pump them up to 110psi according to my floor pump guage. The tube had a split along the seam that was about 4 inches long.
