Anyone ever broken a valve stem on the road?
Had the valve stem on the front crack, plastic support was missing, on the last ride of the year, left me stranded of course. And the first ride of the following season, same outcome, have metal stems in now and expect it not to happen but will buy a valve just in case I or a ride member have a problem.
