Muc-Off Big Bore Lite Tubeless Valve

The Muc-Off Big Bore Lite Tubeless Valve solves one of the most common frustrations in tubeless setup: restricted airflow. Its patent-pending straight-through internal design delivers up to 230% more airflow than a standard Presta valve — meaning faster inflation, fewer clogs, and no need to remove the valve core to add sealant or seat a tire. The integrated ball valve closes reliably under pressure, and the built-in lever lets you fine-tune pressure on the fly without tools. Machined from 7075 aluminum with a stainless steel ball valve, the Big Bore Lite is fully serviceable and built to handle repeated use on demanding terrain. Available in Black or Red, both at 60mm stem length. Airflow: up to 230% more than traditional Presta valves Material: 7075 CNC-machined aluminum, stainless steel ball valve Stem length: 60mm Colors: Black, Red
