I have three spare tubes in the saddlebags right now. If I recall
properly no two have valve stems of the same length. The rear tube on teh
bike right now, the stem is something like 5cm (2") long, while the one of
the front is more like half that.
Why? Why aren't all valve stems more or less the same length? Why would
one need a valve stem 5cm long?
