Big Bore. Big Flow. No Compromise.
Let’s be honest, Presta valves have been holding us back for way too long. The same tired design, barely touched in decades. That tiny pin? It’s like trying to sip a smoothie through a cocktail straw. We knew there had to be a better way. So, we made one.
Introducing the Big Bore Tubeless Valves, the world’s first straight-through, no-core, high-flow tubeless valve system. Zero obstruction. Maximum airflow. Total game-changer.
Born from Frustration. Built for Flow.
As riders ourselves, we were fed up. Tubeless setups are awesome—until you’re battling with slow inflation or struggling to seat a tyre because your airflow’s bottlenecked at the valve. So we started asking the right questions. What if we removed the valve core altogether? What if there was literally nothing stopping the air from blasting into the tyre?
That question turned into a full-on engineering mission. We took inspiration from ball valve systems used in industrial applications, where airflow isn’t just important—it’s everything. The challenge? Shrinking that tech down into something slick, reliable, and bike-ready.
No Core. No BS.
What we came up with isn’t just a tweak. It’s a total redefinition of what a tubeless valve can be. Big Bore delivers unrestricted airflow straight into your tyre, no pin, no plunger, no restriction. Just raw, efficient inflation power. It's faster, smoother, and seats tubeless tyres like a dream.
Unlike other so-called "high-flow" valves that still rely on internal pins, Big Bore rips up the rulebook. It's in a league of its own.
The Dipstick: Sealant Check, Made Simple
We didn’t stop there. Big Bore comes with our custom Dipstick system, a super slick way to check your sealant levels without removing the tyre. Since there’s no valve core, the dipstick slides straight through, giving you a quick and mess-free read on how much juice is left in the tank. It's part of a smarter tubeless ecosystem that just works.
Experience It to Believe It
Once you get your hands on Big Bore, you’ll wonder how you ever lived without it. It’s not just a valve. It’s the future of tubeless.
No core. No compromise. Just flat-out performance.
