Muc-Off BIGBORE LITE TUBELESS VALVES Large Tubeless Valves Muc-Off

Coreless Tubeless Valve: Coreless Structure Increases Airflow During Pumping for Easier Bead Seating

This new design boasts 230% more airflow than 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.

Reducing air resistance makes pumping easier and tubeless setup simpler.

Furthermore, since it doesn't require a valve core, you no longer need to remove the core when filling with sealant. With the BIG BORE valve, you can easily fill by simply twisting the knob.
This also eliminates issues caused by sealant clogging.

Fine adjustments to air pressure can also be easily made by simply twisting the knob.

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

The BIGBORE LITE can still be used with Presta valve-compatible pumps.
