Muc-Off Big Bore Lite Tubeless Valve Stems - Large, 45mm, Black

Say goodbye to the hassle of traditional tubeless valves that clog up and require valve cores to be removed to fill sealant with sufficient air flow during set up. Big Bore Valves are engineered with precision and designed to deliver maximum air inflation simply and efficiently. Crafted from 7075 aircraft grade CNC machined aluminum construction with a stainless-steel ball valve, this fully serviceable valve is built to withstand the toughest rides, whatever the conditions. This patent-pending design sets a new standard in high air flow tubeless tire systems with a revolutionary ‘Straight through’ internal design for maximum airflow fire power, allowing higher air volume per pump, reduced sealant clogging and easier tubeless setup.
