Introducing our latest innovation in tubeless valve technology: The Big Bore Valve range. Engineered with precision and designed to deliver maximum inflation simply and efficiently, this patent-pending valve sets a new standard and is the benchmark in high air flow tubeless tyre systems with a revolutionary ‘Straight through’ internal design for maximum airflow fire power. Featuring a cutting-edge, integrated ball valve system, the valve ensures lightning-fast airflow, turbocharging the sealant filling process. Say goodbye to the hassle of traditional tubeless valves that clog up and require the valve core to be removed to fill sealant and achieve sufficient air flow during tubeless set up. Our Big Bore Lite offers up to 230% higher air flow than traditional Presta valves thanks to the straight through bore design. With our ball valve construction and integrated lever, you can quickly open and close the valve for effortless airflow control, and even fine tune your pressure whilst you're out riding. Crafted from 7075 aircraft grade CNC machined aluminium construction with a stainless steel ball valve, this fully serviceable valve is built to withstand the toughest rides, whatever the conditions. The Muc-Off Big Bore Valves are available in four different sizes to fit most rims and come in six different rad colours. MAXIMUM PERFORMANCE: The latest in valve innovation is coming to you fresh from the Muc-Off R&D team to deliver the highest level of airflow and the ability to finetune your tyre pressure unlike ever before. FULL BORE, NO CORE: Our new valves do not have a traditional valve core. Instead they have a straight through internal design that maximises airflow and makes sealant application a breeze. PRESTA FITMENT: Big Bore Lite Valves are compatible with Presta Pump heads and offer a massive increase of 230% Airflow vs standard Presta Valves! VARIETY OF COLOURS: Muc-Off valves are available in six different eye-popping colours so that you can customise your ride to your heart’s content.
