Muc-Off Big Bore Hybrid Tubeless Valve Stems

The Big Bore Hybrid valves feature a high-flow design that allows significantly more air to pass through at once. This makes seating stubborn tubeless tires much easier and prevents the sealant clogs that often plague standard, narrower valves.

Yes, these are specifically engineered to work with tire inserts. The design ensures that sealant can flow freely around the insert without getting backed up or blocking the valve core.

Installation is straightforward and similar to standard valves, requiring only a standard wrench or valve tool to tighten the lock nut. Because they are Schrader valves, you can use any standard bicycle pump or compressor without needing an adapter.

These valves are 75mm long, which is a versatile length suitable for most standard mountain bike and gravel rims. However, you should measure your rim depth before purchasing to ensure you have enough stem length protruding to attach your pump head comfortably.

Muc-Off uses a durable anodized finish designed to withstand the elements and regular use. While normal wear and tear from trail debris is possible, the color is built to remain vibrant and resist chipping better than standard paint.
