PRODUCT DETAILS

The Iconic SILCA Presta Only Head (formerly the 30.0) has been updated during it's transition to American production.  The classic brass material has been replaced by the much more exotic 17-4 Stainless Steel, a precipitation hardening stainless utilized in aerospace, petrochemical processing, military aircraft, and even as ultra-high strength bicycle tubing.  Whereas brass may have been a material to last a lifetime, 17-4 is a material to last many lifetimes.  17-4 is more than 6X stronger than brass and 4X harder resulting in parts that last longer and are nearly impossible to damage or wear out.  

In a world where aluminium is used to replace brass for cost, and plastic is used to replace aluminium 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 new 242 gasket utilizes a high tech and very red, fully synthetic elastomer base material rather than a carbon black filled natural rubber of previous gaskets.  This unique bright red gasket borrows from industries which require air-tight seals in the harshest of environments, and tests to a life expectancy of more than 5X the carbon filled rubber or Buna-N materials used previously.  New Two-Stage seal geometry seals on both 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!

Pre-Order

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

You Pre-Order is prioritised (at no additional charge); meaning that, as soon as the product arrives with us, we can wrap it straight back up and get it sent out to you - it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

Estimated Delivery Dates

Estimated Delivery Dates are given on Pre-Order and Pre-Launch products. They are for indication purposes only and can change at any time without notice.

The dates we provide are based on indications given by our suppliers. Whenever we get updated information from our suppliers we will endeavour to update the Estimated Delivery Dates provided on product pages.
