catastrophic wheel failure - why?
Look at the photos below of what happened to my wheel today:
Facts are as follows:
This wheel was 36-spoke, 3-cross, custom built, tensioned, and true.
The wheel had about 500 miles on it when it detonated.
The tire was a WTB Slickisaurus 700x37c inflated to (Mfg. recommended) 85 psig.
The tube showed about a 9-inch-long smooth split on the spoke-side of the tube
The rim tape was not punctured
The wheel detonated with a bang on smooth pavement at about 19 mph
The rim did NOT fail at the weld - the weld is still intact.
The wheel bead showed no signs of damage other than where it was punctured by the broken rim
The LBS does NOT think this was caused by the bead coming loose from the rim (their opinion)
What caused this rim to fail?
What can I do to prevent this from happening again? (I'm lucky to be alive)
Does Mavic owe me another wheel?
I have three other wheels with the same rims - am I at risk from them too?
