These Aluminum 90-degree valve stems are for use with tubeless tires only. They attach securely to the rim with a lock nut so the valve stem cannot be bent. Access to the valve stem is greatly increased due to the 90 degree design. The angled design also reduces the effect of centrifugal force on the valve core, which can cause a loss of air pressure in the tire. These valve stems come in a pack of 2 and include: 2 valve stems, 2 lock nuts, o-rings, valve cores, and valve caps.
Used by many top-level AMA teams.
Fitment: OEM - 11.3mm, fits most Japanese OEM Wheels. Aftermarket (A.M.) - 8.3mm, fits Antera, Marvic, Marchesini, OZ Racing and Brem wheels. Available in blue, black, gold, red and silver.
