The Iconic SILCA Presta Chuck in aluminum utilizes the highly efficient push-on design to securely seal on Presta valves with no levers or buttons. A Two-Stage seal geometry seals on both the valve stem and at the base of valve core threads resulting in a more positive seal and improved durability.  The new gasket 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!


  • Iconic Silca Presta Head Design - in use by more pro team and shop mechanics than any other!
  • Full Synthetic Elastomer 242 Gasket
  • 5X the durability of traditional rubber materials
  • Pressure amplifying dome geometry uses air pressure to clamp valve stem
  • Schrader valve thread on hose side threads into any Schrader compatible hose attachment
  • Hand-Crafted with pride in Indianapolis, USA
