What are the causes of a valve tear off?
Valve tearing can be caused by the valve being caught by some road or trail debris like a rock or stick. It can also be caused by the valve lock nut being threaded onto the valve too tightly before the tube is inflated - the valve can then tear away from the inner tube when the tube is inflated. For this reason, we recommend to only thread the lock nut onto the valve once the tube has been inflated.
