Presta Chuck

The Iconic SILCA Presta Only Head (formerly the 30.0) has been updated during its transition to American production.  The highly efficient push-on design securely seals on Presta valves with no levers or buttons to operate.

Who's it for?

The uncompromising cyclist that demands a gasket that slips onto the valve stem with a positive and satisfying 'click', while unique internal geometry actually utilizes line air pressure to compress the gasket onto the valve stem: the higher you pump, the harder it grips the stem!
