Reply to "Large Diameter Campy Clones available from American Republic Wheels"

Racing motorcycles and Bonneville cars run bent valve stems with the cap end set in the trailing position, to lessen the possibility of centrifugal force sucking the valve core down & losing air at the worst possible time even with a cap. The usual ones are 80 degree aluminum valves. They will not fit a stock Campy drilling but for your aftermarket wheels, they may fit or simply drill a new hole. I got mine decades ago; Google 'angled valve stems'.
