Description
The Muc-Off Big Bore Lite Tubeless Valve Stems are 70mm long and feature an iridescent finish. Designed to improve tubeless tire setup, these valves eliminate the need to remove valve cores when adding sealant, allowing for better airflow during inflation. Made from 7075 aircraft-grade CNC machined aluminum with a stainless-steel ball valve, they are durable enough for demanding conditions. The patent-pending straight-through internal design increases airflow up to 230% compared to traditional Presta valves, reducing sealant clogging and making tubeless setup easier.
These coreless valves have an integrated lever for quick opening and closing, enabling precise pressure control on the go. They include seals, O-rings, and a serviceable design with spanner flats on the head, lever, and body for maintenance. The base features a 4-way tire insert airflow design compatible with most tubeless inserts. Installation and removal are simplified with a 4mm machined hex key slot. Various rubber bases are included to ensure a proper fit and seal with multiple rim types.
