Silca Stainless 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!

Key Features:

• Iconic Silca Presta Head Design - in use by more pro team and shop mechanics than any other!
• 17-4 Stainless Material, 6X the strength and 2X the hardness of Brass
• Full Synthetic Elastomer 242 Gasket with 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

Occasionally, without notice, manufacturers change product design and/or specifications.
