Silca Aluminum Presta Chuck

The Iconic Silca Presta Chuck in aluminum. The highly efficient push-on design securely seals on Presta valves with no levers or buttons to operate.



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 utilises line air pressure to compress the gasket onto the valve stem: the higher you pump, the harder it grips the stem!

The utmost care has been taken to machine the part using mono-crystalline diamond tooling to get the perfect surface finish, while the final feel of the part benefits from an investigation into more than 20 different styles and depths of knurl so that it will feel just-so in your hands as it provides a lifetime of useful enjoyment.
