Introducing the Big Bore Valve range—our latest breakthrough in tubeless valve technology. Precision-engineered for maximum inflation speed and efficiency, this patent-pending valve redefines high airflow tubeless systems with its revolutionary straight-through internal design, delivering unmatched airflow power.

Equipped with an advanced integrated ball valve system, it enables lightning-fast airflow that supercharges sealant filling. Say goodbye to clogged valves and the hassle of removing valve cores during setup.

The Big Bore Lite provides up to 230% more airflow than traditional Presta valves, thanks to its straight-through bore design.

Its ball valve and integrated lever let you easily open and close the valve for seamless airflow control—and even fine-tune tire pressure on the trail.

Made from 7075 aircraft-grade CNC-machined aluminum with a stainless steel ball valve, this fully serviceable valve is built tough to withstand the harshest conditions and longest rides.
