Review on 🔒 Stans No Tubes 40mm Presta Valve Extenders with Threaded Design by Eric Basler

If you're trying to convert high profile wheels to tubeless, this is the ONLY option. If you have never used a good valve extender: * Remove the valve core. * Screw it into the valve stem (I also wrapped the little threads in teflon tape), rubber side first. * Use a socket wrench or needle nose pliers. to ensure they are tight.* Screw the valve core into the open end.* After inserting the tubeless valve stem into the rim, tighten the locknut securely, even if using the rim tape version.
