Product Description TCS valves come in anodised aluminium and are available in 34 and 46 mm lengths, making them compatible with rims of different depths. The knurled lock nut also guarantees full compatibility with different rim holes. Thanks to the even pump interface as well as the removable valve insert, the precise placement of the tyre bead and the tubeless set-up become child's play.
