Our opinion

A high-performance preventative product used in the Mountain Bike World Cup by the UCI Massi professional team.

Bruno V.

Road specialist

Massi Air Protective 2 puncture-prevention fluid contains micro-particles that give this product remarkable properties, with fast and effective sealing. Compatible with tubeless and tubeless-ready MTB and road tyres, it seals air leaks hermetically in a matter of seconds.

A key feature is that the seal formed at the puncture site remains flexible, allowing it to move with the tyre and remain effective even in the harshest conditions.
