Description
The Muc-Off Big Bore Lite Tubeless Valve Stems in XLarge (60mm) feature an iridescent finish and are designed to simplify tubeless tire setup and inflation. These valves have a straight-through internal design that provides up to 230% more airflow compared to traditional Presta valves, allowing for faster inflation and reduced sealant clogging.
Made from 7075 aircraft-grade CNC machined aluminum with a stainless-steel ball valve, they are durable and serviceable. The valve includes a coreless ball valve construction and an integrated lever for easy airflow control, enabling quick opening and closing as well as pressure fine-tuning during rides.
Additional features include a serviceable design with 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 easy installation and removal. Multiple rubber bases are supplied to ensure a secure fit and seal with various rim types.
