Imagine pumping up your tubeless bike tires in half the time and twice as easily. Muc-Off is making that dream a reality with its new Big Bore Valves. Unveiled at Eurobike after three years of development, these valves go by the slogan “Big Bore + No Core = Extreme Airflow.” And it’s true – they let air flow 2.5 times faster than standard Presta ones. That means quicker tire fill-ups and no-fuss sealant top-offs. Thanks to the patent-pending straight-through design, no more clogs or having to fiddle with valve cores during maintenance, which lets air and sealant flow freely.
The Big Bore Valves are made of high-grade aluminum and steel for tough nails and are built to last inflation set-up. Muc-Off makes them in four different stem lengths – 30mm, 35mm, 45mm, and 60mm – to fit different wheels. They also come in Lite, Hybrid, and Ludicrous variants so that you can pick the perfect match for your riding style. These valves aren’t just about airflow – they’re designed with the rider in mind. A four-way airflow base makes them compatible with push-on and screw-on pumps, while a 4mm machined Hex key slot ensures easy installation and removal.
For the tech-savvy cyclist, these valves pack some serious features. They’re compatible with tire inserts and can be paired with Muc-Off’s Secure Tubeless AirTag Holder for those worried about getting their bike stolen. Muc-Off also plans to release a Valve Servicing Kit to make maintenance a breeze. With everything mentioned, the Big Bore Valves are for riders in all niches, from weekend warriors to professional racers. Only $50 for a set is a small price for smoother, faster, and easier service.
