SILCA 254 Gasket Fits 'HIRO' V.2 LOCKING PRESTA CHUCK
Who's it for?
The cyclist or mechanic who is looking to restore their SILCA HIRO v.2 LOCKING PRESTA CHUCK back to like-new condition by replacing the gasket that creates the strong seal they have come to expect.Why We Designed It | Product Specs | Getting Started
This unique bright red gasket borrows from industries which require air-tight seals in the harshest of environments. It tests to a life expectancy of more than 5X the carbon filled rubber or Buna-N materials used previously. The SILCA 254 Gasket has a large range of compression to make the most of the HIRO v2 LOCKING LEVER PRESTA CHUCK design. Easily fits over most valve stems and then secure clamps to form a tight seal.
Its a gasket, don't get too excited, but it works fine.
If you have a well used Hiro chuck you will need one of these eventually. Works perfectly.
love the fit
Makes my Chuck like new!
