Stay ahead in your cycling ventures with the Silca Presta Chuck, revolutionised in fine aluminium replacing the classic brass. Carefully machined with mono-crystalline diamond tooling, it promises impeccable surface finish and an excellent gripping feel making it your go-to tool for a lifetime.

The cutting-edge, bright red 242 gasket, borrowed from high-demanding industries, offers an air-tight seal in the most challenging environments. Made with fully synthetic elastomer as opposed to the traditional carbon black filled natural rubber, the gasket impressively extends up to 5X the life expectancy. Its new two-stage seal geometry secures both the valve stem and the base of valve core threads – the more you pump, the firmer it grips the stem!
