Stan's Universal Tubeless Valve Stems are available in both durable brass and lightweight aluminum. These valves feature a secure round base designed specifically for Stan’s BST rims, though they are universally compatible with most tubeless rims on the market.

Every stem includes a removable valve core for easy sealant application. Please note that all listed weights—averaging 8g per valve—refer specifically to the aluminum models, which are half the weight of their brass counterparts.
