Description
The Muc-Off Big Bore Lite Tubeless Valve Stems in XLarge (60mm) and black are designed to simplify tubeless tire setup and inflation. These valves feature a patent-pending straight-through internal design that provides up to 230% more airflow than traditional Presta valves, allowing faster inflation and reducing sealant clogging.
Made from 7075 aircraft-grade CNC machined aluminum with a stainless-steel ball valve, the valves are both durable and serviceable. The coreless ball valve, equipped with seals and O-rings, includes an integrated lever for easy opening and closing to control airflow precisely, even during a ride.
The valves have spanner flats on the head, lever, and body, and include a 4mm machined hex key slot for straightforward installation and removal. The 4-way tire insert airflow base is compatible with most tubeless inserts, and the package includes various rubber bases to ensure optimal fit and seal with different rim types.
