40mm Threaded Valve Extenders A pair of 40mm effective length threaded valve extensions for use with removable valve core presta valves. Allows deep section rims to be converted to tubeless use by way of external threads for securing the presta nut. The only externally threaded valve extenders on the market.
CNC machined aluminum valve extension, 2 grams each
Rubber o-ring seals inside the valve to eliminate leaks
Adds 40mm of length to any removable core presta valve
Love Stan’s no tubes extenders. With removable core tubes installation of the extenders is very simple. I add some Teflon tape around the 2 connecting points and never have a problem with air leaking or rattling.
