Stans No Tubes lightweight valves are exceptionally reliable and work perfectly with most Presta-drilled tubeless rims. Compatible with Stan's BST models as well as various other tubeless rim models. Removable valve core makes adding sealant easy. Fits up to an 8mm valve hole. 35mm depth is optimized for most shallower MTB rims, but you may want the longer "road" valves if you have deeper carbon rims. Sold as a pair.
