Dynamic Tubeless tire valve Barkeeper

This complete valve kit Barkeeper is the best choice for all tubeless setups. The valves are easy to install and designed to be 100% compatible with all brands and types of wheels. CNC machined from aerospace-grade 7075 aluminium, with an innovative 5-hole design for optimal airflow and full insert compatibility. The 4 mm Allen key slot allows for easy assembly and removal of the valve. Resistant to temperature, UV rays, and ozone. Compatible with all Presta-style foot and hand pumps. In this kit: - 2 complete tubeless valves (including black valve cores, ultralight valve caps, rubber bases, O-rings, and lock nuts). - 2 sets of alternative rubber bases, ensuring 100% compatibility. - 2 additional black valve cores. - 1 ultralight purple valve cap with a built-in tool for removing the valve core. INSTALLATION: 1. Remove the valve cap, lock nut, and O-ring from the valve stem. 2. Select the correct rubber base for your rim. If your rim is curved, use the round rubber base and choose the right width. If your rim is square, use the square rubber base. Ensure the base is fully slid to the bottom of the valve before installation. 3. Push the valve through the valve hole in the rim from the outside to the inside. Place the O-ring on the end of the valve and slide it down until it is positioned on the rim. 4. Screw the lock nut onto the valve and tighten it against the O-ring and the rim. 5. Use a 4 mm Allen key at the base of the valve to hold it in place and push the base of the valve against the seat of the rim. At the same time, tighten the lock nut until it is hand tight. It's normal for the O-ring to be slightly pushed, indicating a tight seal. Do not overtighten the lock nut to avoid leaks. 6. If you choose to ride with valve caps, choose either the 2 black ones or swap one for the purple valve cap with the core removal feature on your other wheel.
