What Makes the Reserve Fillmore Valve a Tubeless Game Changer?

The Reserve Fillmore Valve reimagines tubeless setup from the ground up, replacing the fragile threaded valve core found on conventional valves with a patented high-flow internal design that dramatically speeds up inflation and sealant injection. The 50mm length fits modern deep-section rim profiles perfectly, and the precision-machined aluminum construction resists the corrosion and thread wear that plague lesser valves over time. If you have ever wrestled with a clogged or stripped valve core mid-ride or during a pre-race setup, the Fillmore's tool-free, clog-resistant design is a revelation.

Reserve engineered the Fillmore to work with any tubeless-compatible rim, making it a universal upgrade regardless of your wheelset brand. The anodized black finish holds up to repeated use and UV exposure without fading, and the 50mm depth clears even the deepest carbon rims with room for a standard pump head. These valves are built for riders who run aggressive tire setups, frequent sealant top-offs, or race schedules that demand fast, reliable tubeless performance every time they roll out.
