Reserve Fillmore Valve

Standard valves have a narrow core that restricts airflow, making it difficult to pop the tire bead onto the rim. The Fillmore's coreless architecture opens up the entire valve stem, allowing for a massive increase in airflow that helps seat stubborn tubeless tires much faster.

That is the primary problem these valves solve. Because there is no traditional valve core for sealant to pool and dry inside, the Fillmore is virtually immune to the clogs that typically plague standard tubeless valves.

Yes, they are fully compatible with standard Presta-style floor pumps. You do not need any special adapters or tools to inflate your tires.

Instead of depressing a pin, you simply loosen the valve cap slightly to bleed air. This allows you to release small, controlled amounts of air for precise pressure adjustments without the risk of accidentally dumping too much pressure at once.

These valves have a 70mm stem length, which is designed to fit a wide range of rim depths. Be sure to measure your rim's depth to ensure you have enough stem length protruding for your pump head to attach securely.
