Description
The Muc-Off Big Bore Lite Tubeless Valve Stems are 80mm long, 3XLarge size, and black in color. Designed to simplify tubeless tire setup, these valves feature a patented straight-through internal design that provides up to 230% higher airflow compared to traditional Presta valves, allowing faster inflation without removing the valve core. Made from 7075 aircraft-grade CNC machined aluminum with a stainless-steel ball valve, the valve is fully serviceable and built to handle tough conditions. It includes a coreless, ball valve construction with an integrated lever for easy opening, closing, and fine tuning of tire pressure while riding. The valve has spanner flats on the head, lever, and body for maintenance, a 4-way tire insert airflow base compatible with most tubeless inserts, and a 4mm machined hex key slot for installation and removal. Various rubber bases are included to ensure a secure fit and seal with different rim types.
