MUC-OFF V2 Tubeless Valves Black

The Muc-Off V2 valves are far more than simple coloured accessories. Completely redesigned, they are now made from aerospace-grade 7075 aluminium, making them lighter and more durable than the previous version.

Their major innovation lies in the 6-slot internal airflow system at the base of the valve. This design allows air and sealant to flow freely, even if you use tyre inserts (protective foam inserts). No more clogged valves or difficulty seating the tyre during fitting.

What length should I choose for my rims? For standard MTB rims, 44 mm is sufficient. If you have deep-section rims (road or carbon), 60 mm or 80 mm will be needed so the valve protrudes enough for the pump.

Does sealant clog the valve? Thanks to the new base design, the risk is greatly reduced. However, it is still advisable to remove the core from time to time to clean it if you use a very thick sealant.

Is installation difficult? No, the installation is very intuitive. The choice of supplied seals allows you to create a hand-tight seal without needing to over-tighten the nut.

Why is 7075 preferable? This alloy is much harder than standard aluminium. This prevents the valve from bending or breaking if you give the pump a slightly rough push.
