Muc-Off Big Bore Hybrid Tubeless Valve Stems

The Big Bore design features a significantly wider internal diameter, which allows for a much higher volume of air to pass through the valve. This increased airflow makes seating stubborn tubeless tires much faster and easier, as you can get the bead to pop into place with less effort.

Yes, these valves are specifically engineered to be compatible with tire inserts. The design ensures that the airflow and sealant passage remain unobstructed, preventing the common issue where inserts block the valve opening.

These stems are 60mm in length. You should measure your rim depth to ensure you have enough clearance for the pump head to attach securely; generally, you want at least 15-20mm of valve stem protruding from the rim.

No, these are standard Schrader valves, so they are compatible with any standard floor pump or compressor equipped with a Schrader head. The 'Big Bore' refers to the internal architecture, not the external connection type.

Absolutely. While they are optimized for use with inserts, they function perfectly well as standard high-flow tubeless valves. You will still benefit from the easier tire seating and improved airflow regardless of your setup.
