Promising 3 times the airflow of a Presta valve with a revolutionary no-clog design, the Reserve Fillmore valves represent a game-changing leap forward in technology that will eliminate most of the faff that's normally associated with working with tubeless tyres and sealants.

The coreless design of the Fillmore valves makes it easy to seat tubeless tyres without the need for a compressor or charger pump while also preventing the valve from getting clogged up with sealant, thanks to its self-clearing poppet.

Fillmore valves are compatible with Presta pump heads, gauges, and sealant injectors, and the threaded valve cap allows for micro-adjustable pressure release.

Compatible with MTB, Gravel, and Cyclocross rims with depths between 18-28mm.

Who's this item for: The Fillmore valve is for anyone that's sick of having their valves clog with sealant or having to remove their valve core to seat their tubeless tyres.

Length: 50mm (longer, road rim compatible options are in the works)

Rim well compatibility: Compatible with MTB, Gravel, and Cyclocross rims with depths between 18-28mm. The 28mm maximum rim depth means that 50mm valves are not compatible with most road rims on the market. Longer valves are in the works though!

See the rim compatibility chart under the Links & More Info tab: *For rims not listed, please refer to the rim manufacturer’s website for rim
depth information. 50mm valves will fit max 28mm deep rims.

Removable valve core: No, the Fillmore valve doesn't have a valve core which means that it has 3x more airflow, allowing you to seat stubborn tubless tyres and inject sealant through the valve without having to mess around removing cores or worrying about blockages caused by sealant.

Valve cap type: The valve cap is an integral part of the valve system that opens and closes the valve and operates the micro-adjust feature. The system is designed to hold air pressure with or without an air cap fitted but it is best practice to keep it safely attached to the valve.

Materials: 7000 series aluminium with a one-piece stainless steel internal rod. Covered by a lifetime warranty for the original owner.

Rim protection compatibility: Yes, they are compatible with tyre inserts but the poppet pushes against the insert when you release air pressure, so it can take a bit of additional force on the cap to let the air out of the tyres.

Other compatibility: Not compatible with Tyrewiz as installation requires you to remove a Presta valve core the Fillmore's high-flow, no-clog design does not have a valve core.
