High-Flow Tubeless Valve Kit for Effortless Inflation

Overview

The Muc-Off Big Bore Lite sets a new benchmark in airflow performance for tubeless systems. With its patent-pending ‘straight through’ internal design, it eliminates clogs and delivers up to 230% more airflow compared to traditional Presta valves, making tubeless set-up faster and easier.

Lightning-Fast Airflow Control: Featuring an integrated ball valve system with a built-in lever, this design ensures rapid inflation and effortless sealant filling. Unlike standard valves, there’s no need to remove the valve core, giving you full control over airflow for both quick inflation and precise pressure adjustments while out on the ride.

Built for Performance and Reliability: Every detail of the Big Bore Lite is engineered for strength and precision. Crafted from 7075 aircraft-grade CNC machined aluminium with a stainless-steel ball valve, it is lightweight yet durable, built to handle the toughest conditions and endless miles of riding.

Sealant-Friendly Innovation: The innovative design not only speeds up inflation but also turbocharges the sealant filling process. Riders can now say goodbye to blocked valves and frustrating setups, enjoying a hassle-free experience with maximum efficiency.

Whether you’re tackling gravel, MTB trails, or road adventures, the Muc-Off Big Bore Lite is designed to withstand it all, keeping your tubeless system running at peak performance.
