New rubber on your rig may elicit fantastic dreams of drifting corners, cutting berms and hooking up at crucial moments, but the sheer thought of getting those new tubeless tires mounted, inflated and seated can cloud those dreams with dread. The reality is that as mountain bike technology has evolved exponentially year after year, that silly little Presta valve you’ve been cursing has held steadfast for nearly a century. A CENTURY!?!?! Until today. Reserve is rewriting the future of tubeless tire systems with the introduction of Fillmore, a completely new take on tubeless valves. This new, high volume design allows triple the airflow, while its revolutionary self-clearing poppet eliminates clogged valves. Finally, its threaded cap allows you to back-off and air down to the perfect tire pressure with micro-adjustable precision. FEATURES: High Flow: 3 X air flow makes seating and inflating tires a snap No Clog: Eliminates clogging and busts through dry sealant Micro-Adjust: Airs down to the perfectly dialed tire pressure Compatible with all Presta pump heads and most sealant injectors, Fillmore is backward-compatible with whatever you got, and forward-thinking in every way. Made for mountain, gravel and 'cross rims up to 28mm deep, Fillmore is one of those upgrades you don't know you need until you try it. So, what are you waiting for? Get that new rubber mounted up, drop in and find out what you've been missing!
