The new TUBELESS VALVES are available in stem lengths of 40 mm, 60 mm and 100 mm and are a breeze to fit. There is a suitable valve solution for every rim depth. The valve base can be securely mounted in the rim with a hex key (4 mm) without over tightening. The shortened cone ensures a low installation height and thus more space for the tire beads. Thanks to the large valve inner diameter (4 mm), the tire can be inflated with air and sealing fluid particularly effectively. SV 40 mm.
