Hi all, Riddle me this: Last time you bought new tyres for your bike did you get new valve stem inserted in the rims? If so did you have to ask for them? I "enjoyed" what I believe to be staggeringly poor service recently when I bought a new front tyre. I have just discovered that it doesn't hold air (lost 15psi in a week) and lo and behold, to compound the annoying hassles I had getting the tyre I have found that the valve stem is still the old one and is leaking. I didn't specifically ask for a new insert even though the old one leaked very slowly, but assumed that it would be replaced, just as they had been every other time I have bought tubeless car or bike tyres - or at least checked for leaks! Mod: moved to Maintenance forum.
