Muc-Off Big Bore Tubeless Valves

By removing the traditional valve core, the Big Bore system creates a completely unobstructed path for air. This allows for significantly faster inflation and makes seating stubborn tubeless tires much easier.

Yes, these valves are designed for versatility. Each pack includes multiple rubber base options, ensuring you can achieve a secure, airtight seal across a wide variety of rim shapes and sizes.

Yes. Traditional Presta valves have a narrow core that easily traps dried sealant. Because this system uses a ball valve mechanism with a wider opening, it is much less prone to clogging, even with heavy-duty sealants.

Yes, they are designed to work with standard Presta-compatible pumps. The integrated lever on the valve allows you to open and close the airflow manually, replacing the need to unscrew a traditional valve nut.

Installation is straightforward. The base of the valve features a machined hex key slot, allowing you to tighten it securely into your rim using a standard Allen key without damaging the finish.

They are built from 7075 aircraft-grade aluminum, which is exceptionally strong and lightweight. They are specifically engineered to withstand the vibrations and impacts of demanding trail conditions.
