Reserve Wheels Fillmore Cap Kit

The Fillmore valve replaces the traditional, removable valve core with a poppet-style design. This allows for three times the airflow of a standard valve, which makes seating tubeless tires much faster and easier.

Yes. Because the design eliminates the need for a removable core, you can inject sealant directly through the valve stem without any disassembly.

These are 50mm Presta valves designed for rims up to 28mm deep. They are compatible with most mountain, gravel, and cyclocross tubeless setups, but you should measure your rim depth to ensure the stem length is sufficient.

Yes, the high-flow design prevents sealant from pooling and drying inside the valve mechanism, which is a common failure point with traditional Presta cores.

Yes, the Fillmore valve allows for micro-adjustable pressure release. You can easily let out small amounts of air to dial in your tire pressure while out on the trail.

While the anodized finish and color options are great for matching your bike's aesthetic, the primary benefit is the improved airflow and clog-free performance of the valve system itself.
