Muc-Off V2 Tubeless Valve Kit - 80mm Presta, Black, Aluminum, Pair
The Muc-Off V2 Tubeless Valve Kit is built for riders running deeper carbon wheels, tubeless setups, and modern tire insert systems that standard valves struggle to support. These are not basic tubeless valves—they are designed specifically to improve airflow, simplify installation, and reduce one of the most common headaches in tubeless setups: blocked airflow.
The V2 design uses Muc-Off’s Tire Insert Air Flow System with six machined slots at the valve base, allowing sealant and air to move freely even when using foam tire inserts like CushCore and similar systems.
This 80mm version is ideal for deeper road, gravel, and MTB carbon rims where standard valve lengths come up short.

Compatibility & Technical Notes
Good Fit: deep carbon road wheels, gravel wheels, MTB tubeless setups, and riders using tire inserts like CushCore or similar foam insert systems.
Not A Fit: Schrader valve rims, tube-only wheel setups, or shallow rims where shorter valves make more sense.
Valve length matters. This 80mm version is ideal for deeper section rims and many aero wheelsets, but can be unnecessarily long for shallow alloy rims.
Service / Ownership Context
Many tubeless problems blamed on sealant are actually valve problems—restricted airflow, poor seal at the rim bed, or clogged valve cores. Better valves solve a surprising number of “tubeless issues.”
If you run tire inserts, standard tubeless valves often become frustrating quickly. This V2 system is specifically built to prevent that problem.
Fit & Use Signals
Best for:
- Road tubeless setups with deep carbon rims
- Gravel tubeless systems
- MTB riders using foam tire inserts
- Performance riders wanting easier tubeless maintenance
- Wheel upgrades requiring longer valve length
Not ideal for:
- Basic tube-only setups
- Schrader valve wheels
- Shallow alloy rims where shorter valves fit better
- Riders not running tubeless systems
