Big Bore Hybrid Tubeless Valve Stems - Small

Muc-Off Big Bore Hybrid Tubeless Valve Stems deliver high-volume air flow and dependable performance for riders who want faster, cleaner tubeless setup and maintenance. Designed for mountain, gravel, and e-MTB use, these 30mm valves feature a tough, fully serviceable construction and a unique hybrid design that blends the convenience of a Schrader-style head with the precision of a ball valve system.

Crafted from CNC-machined 7075 aluminum with stainless steel internals, the Big Bore Hybrid Valves are built to handle hard use and resist clogging from sealant. The patent-pending straight-through design maximizes air flow—making tire inflation faster and seatings easier, even with tire inserts in place. A lever-actuated ball valve lets riders fine-tune pressure or blast in air on demand, all without removing a valve core.

• High-flow straight-through design allows faster inflation and easier tubeless setup
• Hybrid Schrader-style head works with most screw-on and push-fit pumps
• Fully serviceable construction includes spanner flats and replaceable seals

For riders tired of clogged valves and slow inflation, the Muc-Off Big Bore Hybrid Tubeless Valve Stems offer a smarter, faster air system built for real-world riding conditions.
