The HIRO is SILCA's take on the coveted Japanese all-metal chucks that Euro-pro mechanics used for disc wheel inflation. A side 'lollipop' lever locks it onto the valve stem for a secure, hands-free seal.

Highlights

  • All-metal carbon steel construction
  • Side-lever locking action onto Presta valve stems
  • Designed around disc wheel inflation
  • Swaps onto SILCA Pista Plus in place of the standard chuck

From the pro pits

SILCA's Josh Poertner first saw the design while working with Team CSC at the Dauphiné, where a mechanic was using a rare Japanese all-metal chuck to inflate disc wheels. SILCA refined the design and made it available to riders everywhere.

Serviceable seal

The HIRO V.2 uses SILCA's bright red 254 gasket, which has a large range of compression, fits over most valve stems and clamps down to form a tight seal. Replacement 254 gaskets are available separately.

Compatibility & fit

Presta valves. SILCA's Pista Plus floor pump is designed so you can swap its standard chuck for a HIRO chuck while still using the chuck dock.
