Description
The Muc-Off Big Bore Lite Tubeless Valve Stems are 3XLarge, 80mm, and feature an iridescent finish. These valves are designed to simplify tubeless tire setup by allowing high airflow without removing the valve core. Made from 7075 aircraft-grade CNC machined aluminum with a stainless-steel ball valve, they offer durability for tough riding conditions. The patent-pending straight-through internal design provides up to 230% higher airflow than traditional Presta valves, reducing sealant clogging and making inflation faster and easier. The coreless ball valve construction includes an integrated lever for quick opening and closing, enabling precise pressure adjustment on the ride. Additional features include seals and O-rings, a serviceable design with spanner flats on the head, lever, and body, a 4-way tire insert airflow base compatible with most tubeless inserts, and a 4mm machined hex key slot for easy installation and removal. The valves come with various rubber bases to ensure a proper fit and seal across multiple rim types.
