The WTB Ventil TCS AL Max-Flow is a high-quality tubeless valve designed to make setting up and running tubeless tires easier, cleaner and more reliable. Built around WTB’s proven TCS (Tubeless Compatible System) standard, this valve is engineered to deliver excellent air flow for fast inflation and consistent sealing, whether you are riding mountain, gravel or road tubeless setups. The Max-Flow design helps sealant move freely through the valve, reducing clogging and making it easier to seat stubborn tires with either a floor pump or a compressor.
Constructed from lightweight yet durable aluminum, the WTB Ventil TCS AL Max-Flow offers a strong, corrosion-resistant alternative to basic brass valves, while keeping rotating weight low at the rim. A removable valve core allows for easy sealant top-ups and quick maintenance, and the included rubber grommets are shaped to work with a wide range of rim profiles. This makes the valve a versatile choice for riders who want a dependable, long-lasting tubeless solution that supports aggressive riding, frequent tire changes and year-round use in varied conditions.
