Reserve has rewritten the future of tubeless systems with the introduction of the all-new Fillmore valve, a completely new take on tubeless valve designs. The patented Fillmore valve represents a game-changing leap forward in technology, with a high-flow design that eases tubeless set up and eliminates the traditional, delicate, clog-inciting valve core of yesteryear.

• Fillmore is one of those upgrades you don't know you need until you try it.
• High-Flow, no-clog, micro-adjustments
• 50mm valve made for rims up to 28mm deep
• Airflow - 3 times the airflow as a standard Presta air valve, easing tubeless tire set-up and reducing pumping force
• No clogging - Patented poppet-style design eliminates clogging by shielding air hole from contact with sealant
• Simplicity - Ability to inject sealant without removal of valve core simplifies maintenance
• Adjustable - Micro-air adjustment feature allows for precise trail-side pressure changes
