Description
The Muc-Off Big Bore Lite Tubeless Valve Stems are designed to simplify tubeless tire setup and improve airflow. Measuring 80mm in length and finished in red, these 3XLarge valves feature a precision-engineered, straight-through internal design that allows up to 230% higher airflow compared to traditional Presta valves. This helps reduce sealant clogging and enables faster inflation without the need to remove valve cores.
Constructed from 7075 aircraft-grade CNC machined aluminum with a stainless-steel ball valve, the valves are durable and fully serviceable. They include a coreless ball valve and an integrated lever for easy airflow control and pressure adjustment while riding. The valve heads have spanner flats and a 4mm machined hex key slot for convenient installation and removal. The 4-way tire insert airflow base is compatible with most tubeless tire inserts. The package includes various rubber bases to ensure an optimal fit and seal across different rim types.
