Compatible with all 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, Fillmore is one of those upgrades you don't know you need until you try it.

• Airflow - 3 times standard Presta air flow, 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
