Santa Cruz is rewriting the future of tubeless tire systems with the introduction of Reserve Fillmore, a completely new take on tubeless valves. This new, high volume design allows triple the airflow, while its revolutionary self-clearing poppet eliminates clogged valves. Finally, its threaded cap allows you to back-off and air down to the perfect tire pressure with micro-adjustable precision.

• Compatible with Presta pump heads and most sealant injectors, Fillmore is backward-compatible with whatever you got, and forward-thinking in every way. Made for mountain, gravel and 'cross rims up to 28mm deep
• High Flow: 3 X airflow makes seating and inflating tires a snap
• No Clog: Eliminates clogging and busts through dry sealant
• Micro-Adjust: Airs down to the perfectly dialed tire pressure
• Direct-Inject: Coreless design for no-fuss injection of sealant
