Muc-Off BIGBORE HYBRID TUBELESS VALVES Small Tubeless Valve Muc-Off

BIGBORE HYBRID requires a pump compatible with Schrader valves.

A coreless tubeless valve that increases air flow during pumping, making it easier for the bead to seat, thanks to its coreless structure.

This new design allows for 254% more airflow compared to conventional Presta valves, making it a revolutionary tubeless valve.
The BIG BORE VALVE is an entirely new tubeless valve that reduces air resistance more than conventional French valves, thanks to the development of its new "straight-through" system.

By reducing air resistance, pumping becomes easier, simplifying tubeless setup.

Furthermore, since it doesn't require a valve core, which usually had 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-tuning air 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.

Available in 4 sizes depending on rim height. This is the Small size.
