Baciacally I have some aero rims up to 50mm, so thetwo ways to go are buy 80mm valves (preferable) but very hard to find, neither Condor or Evans, nor Cycle Surgery do them. The second way is to remove the valve on a short valve version and fit extenders, which is time consuming, requires a fiddly small wrench, and is frustrating in the dark on a Brighton night ride!
