Fillmore Tubeless Valves are an update on the venerable Presta valve.

If you're using Presta and tubeless then you're probably aware of some of the problems. These come from the design, which uses a small valve screwed into the stem. This limits the amount of air that can pass through, which can make initial inflation of tubeless tyres a problem. And that small opening is perfect for clogging with sealant.

The Fillmore Valve has opened up and simplified the internals, making going tubeless easier. I've been using them for a few months and so far, no problems.
