Description
The Muc-Off Big Bore Lite Tubeless Valve Stems are 2XLarge, 70mm long, and come in pink. Designed to simplify tubeless tire setup, these valves prevent clogging and eliminate the need to remove valve cores during sealant filling. Made from 7075 aircraft-grade CNC machined aluminum with a stainless-steel ball valve, the valve is durable and serviceable. Its patent-pending straight-through internal design provides up to 230% higher airflow compared to traditional Presta valves, allowing faster inflation, reduced sealant clogging, and easier setup. The valve features a standard Presta head, coreless ball valve construction with an integrated lever for easy opening, closing, and fine pressure control during rides. It includes seals, O-rings, and spanner flats on the head, lever, and body for servicing. The base has a 4-way tire insert airflow design compatible with most tubeless inserts and a 4mm machined hex key slot for installation and removal. Various rubber bases are included to ensure optimal fit and seal across multiple rim types.
