High-flow tubeless valves for faster inflation and easier sealant filling.
Muc-Off Big Bore Hybrid Tubeless Valves are designed to significantly increase airflow through your tubeless system, making tyre inflation, bead seating and sealant filling easier. Their straight-through internal design removes the restriction of a conventional Presta valve core, allowing considerably more air to move through the valve.
An integrated stainless steel ball valve uses a simple lever to open and close airflow, providing quick inflation and straightforward pressure adjustment. With up to 254% more airflow than a traditional Presta valve, the Big Bore Hybrid is particularly useful for larger-volume gravel and mountain bike tyres and tubeless setups that can be difficult to seat.

Why Choose Muc-Off Big Bore Hybrid Tubeless Valves?
The main advantage is airflow. Removing the restrictive traditional valve core allows substantially more air into the tyre, which can make a real difference when trying to seat tubeless beads. The lever-operated ball valve also makes inflation, pressure adjustment and adding sealant straightforward.
Our Thoughts
These make the most sense for riders who regularly work on their own tubeless setups or run larger-volume gravel and MTB tyres. Standard tubeless valves work well for many riders, but the additional airflow of the Big Bore Hybrid can make stubborn tyre setups considerably easier, particularly when using a floor pump rather than a compressor.
