This valve stem is out of production, It is not recommenced to be used on any tubeless rim. we do have a limited supply of them left, the only reason to use this valve is if you have a Stan's ZTR Tubeless rim and the inside hole of the rim has been drilled out larger then 8mm. This valve *will not work* to convert a non-tubeless rim to tubeless, please see our Tubeless conversion systems.
It is recommended if your tubeless rim has a hole smaller then 8mm to use the Universal Valve Stem.
