Everything else on our bikes has evolved astronomically throughout the years. The only thing that has stayed the same is Presta valves. With tubeless tyres being the norm now, it seems that valves need to catch up and make our life easier for fitting tubeless systems. For nearly a century (that's right! A CENTURY) Presta valves have remained the same, it's time for something new.
Introducing the Fillmore valve from our friends at Reserve. They're rewriting the future of tubeless systems, with a completely new take on tubeless valve design. The patented Reserve Fillmore valve is a game-changing leap forward in technology, with a design that eliminates the traditional, delicate, clog-inciting valve core of yesteryear.
FEATURES
AIRFLOW - 3 times standard Presta airflow, easing tubeless tire set-up and reducing pumping force.
NO CLOGGING - Patented poppet-style design eliminates clogging by shielding air hole from contact with sealant
SIMPLICITY - Ability to inject sealant without removal of valve core simplifies maintenance
ADJUSTABLE - Micro-air adjustment feature allows for precise trail-side pressure changes
The Fillmore valve is one of those products that once you try it, you will be wondering how you lived without it. And with no new standards, it easily installs on mountain bike rims up to 28mm in depth and works with all Presta pump heads. So, what are you waiting for? Get that new rubber-mounted up, drop in and find out what you have been missing!
Cheers for stopping by - Keep the wheels spinning!
