The original and still the best tubeless valve stem for most rims and a perfect fit for all Stan's BST rim models. Weighs only 16g, 18g, and 21g per valve for the 35mm, 44mm, and 55mm models respectively. Durable brass construction. Removable valve core makes adding sealant easy. Fits up to an 8mm valve hole.
