Stan's Universal+ Tubeless valves offer modern features to the traditional Presta standard. Stan's further establishes its commitment to improving the ride for cyclists everywhere with the new Universal+ tubeless valve. The Universal+ tubeless valve features a black-anodized, two-piece alloy base with a traditional Presta valve core. Like it's Exo-Core tubeless valve sibling, the Universal+ features five airflow holes (four on the sides, one on the bottom) to ensure free flow of air and sealant even with tire inserts, while a uniquely shaped rubber stopper guarantees a reliable seal on modern rim shapes. The same TAP cap and secure-lock nut featured on the Exo-Core tubeless valve provides the finishing touches here on the Universal+. Speaking of Exo-Core, the Universal + valve can easily be upgraded by simply removing the Presta core and installing an Exo-Core housing kit (sold separately). For some customized color coordination, the Universal+ valve is compatible with Stan's Tubeless Valve Color Kits (sold separately), which are available in six color choices.
