Muc-Off Presta Valve Stem V2

These valves are machined from 7075 aluminum, which is significantly stronger and more durable than the 6061 aluminum typically used in standard valves. This allows for a lighter construction without sacrificing the structural integrity needed for a reliable tubeless seal.

Yes. The base of the valve features a specialized 6-slot machined channel that allows air and sealant to pass through freely, even when a foam insert is pressed against the valve opening.

No extra tools are required for the initial setup, and the kit includes a dedicated valve core removal tool. This makes it easy to remove the core for quick sealant top-ups or to clear any potential clogs.

These are standard Presta valves designed for tubeless-ready rims. While they fit the vast majority of modern tubeless setups, ensure your rim depth is compatible with the 60mm stem length to guarantee you have enough clearance for your pump head.
