Silca 17-4 Stainless Presta Head

In a world where aluminum is used to replace brass for cost, and plastic is used to replace aluminum for cost, and so on, we felt the need to re-imagine this most iconic of cycling tools as an heirloom-quality objet d'art. 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. This is truly a tool you will hand down to your children and them in turn onto theirs.

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.
