Stan's NoTubes Alloy Valve Stems

Stan’s NoTubes Alloy Valve Stems deliver ultralight tubeless performance in a precision-engineered design that refuses to compromise sealing security for reduced weight. Don’t let their minimal mass fool you—these thoughtfully built valves provide reliable airflow, easy sealant management, and universal rim compatibility, giving tubeless riders the dependable inflation interface they need without the heft of traditional brass stems.

Constructed from lightweight aluminum, each valve weighs only 8g, 9g, or 10g depending on length (35mm, 44mm, 55mm), cutting rotational weight without sacrificing durability. The secure round base forms a stable seal across most tubeless rim beds, offering a perfect fit for all Stan’s BST and BST-R rims while maintaining broad compatibility with other modern tubeless platforms. A removable valve core simplifies adding or refreshing sealant, ensuring quick maintenance and consistent long-term performance. Finished in a clean black anodization, they integrate seamlessly with any wheel setup designed around up to an 8mm valve hole.
