Muc-Off Big Bore Lite

By removing the traditional valve core, the Big Bore Lite creates a straight-through channel that significantly increases airflow. This allows you to seat tubeless tires much faster and makes injecting sealant through the valve stem effortless.

Yes, they are specifically engineered to be compatible with most tubeless tire inserts. The 4-way air flow base ensures that even with an insert pressed against the valve, air can still pass through freely.

Yes, they are designed to work with standard Presta pumps. However, because they use a unique lever-actuated mechanism rather than a traditional core, you will use the integrated lever on the valve to open and close the airflow instead of unscrewing a valve nut.

It means the valve is designed to be taken apart, cleaned, and repaired rather than thrown away if it gets clogged or damaged. You can easily access the internal stainless steel ball mechanism to clear out dried sealant or debris, extending the life of the valve significantly.

The 35mm length is a standard size that fits most mountain bike and gravel rims. However, if you are running deep-section aerodynamic rims, you may need a longer valve stem to ensure the head of the pump can securely attach.
