We think of our Presta valve as a constant. The fact is that it has gone unchanged for nearly a century. But since we've embarked on a new age of modern tubeless technology we have started to question if it's truly our best option. That's where Reserve's new Fillmore Valves come into play. There's no fussy valve core to cause issues and it has three times the flow of a standard Presta valve. The key here is high flow and no clogging. With Reserve's patented poppet-style design and simple adjustability this valve is practically impossible to clog. Plus it doesn't have a core to bend in case of a crash. For a tiny component the Fillmore Valve receives top-quality treatment.
