Muc-off BIGBORE LITE TUBELESS VALVES XL Tubeless Valve Muc-Off

Coreless tubeless valve that increases air flow during pumping by having a coreless structure, making it easier for beads to seat.

This new design of tubeless valve improves airflow by 230% compared to conventional Presta valves.
The BIG BORE VALVE is a completely new tubeless valve that reduces air resistance by 230% compared to conventional Presta valves, thanks to the development of its new "straight-through" system.

By reducing air resistance, pumping resistance is reduced, making tubeless setup easier.

Additionally, because it doesn't require a valve core, which usually needs to be removed when filling with sealant, the BIG BORE valve allows for easy filling by simply twisting the knob.
This also eliminates problems caused by sealant clogging.

Fine adjustment of tire pressure can also be easily done by simply twisting the knob.

It uses 7075 aluminum, also used in aircraft, and a stainless steel ball valve, boasting durability that can withstand harsh environments.

The BIGBORE LITE can be used with Presta valve-compatible pumps, just like before.
