Muc-Off Big Bore Lite Tubeless Valves
Introducing the latest innovation in tubeless valve technology: The Big Bore Valve range. 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 firepower.
Featuring a cutting-edge, integrated ball valve system, the valve ensures lightning-fast airflow, turbocharging the sealant filling process. 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 airflow during tubeless setup.
The Big Bore Lite offers up to 230% higher airflow than traditional Presta valves thanks to the straight-through bore design.
With its ball valve construction and integrated lever, the valve allows for quick opening and closing, effortless airflow control, and even fine-tuning of pressure while riding.
Crafted from 7075 aircraft-grade CNC machined aluminium with a stainless steel ball valve, this fully serviceable valve is built to withstand the toughest rides, whatever the conditions.

Q & A
1 question answered
Are these compatible with Vittoria Air-Liner inserts in the tyres?
Hi there, We can't confirm these against Vittoria Air-Liner inserts, I'm afraid. The Big Bore Lite is a high-flow coreless valve, but an insert sits against the rim bed and can sit over the valve opening, so the combination depends on the specific insert and rim. Vittoria supply their own multiway valves with the Air-Liner road and gravel kits for exactly this reason. The safest check is to confirm directly with Vittoria, or get in touch via https://www.sigmasports.com/contact-us and we can look into it with you. Many thanks Joe W
