Big Bore Tubeless Valves

Engineered with precision and designed to deliver maximum inflation simply and efficiently, this patent-pending valve sets a new standard and is the benchmark in high air flow tubeless tyre systems with a revolutionary ‘Straight through’ internal design for maximum airflow fire power. Say goodbye to the hassle of traditional tubeless valves that clog up and require the valve core to be removed to fill sealant and achieve sufficient air flow during tubeless set up.

Big Bore Lite offers up to 230% higher air flow than traditional Presta valves thanks to the straight through bore design. Big Bore Hybrid offers up to 245% higher air flow than traditional Schrader valves thanks to the straight through bore design. Crafted from 7075 aircraft grade CNC machined aluminium construction with stainless steel ball valve, this fully serviceable valve is built to withstand the toughest rides, whatever the conditions.
