The world’s lightest steel disc rotor
Some said ARO08 would never work….then 3 years and several World Championships later others said it would be impossible to go lighter whilst offering the performance level that made ARO08 the bestselling aftermarket rotor of all time….well they were wrong and Ai2 proves it !
Ai2 offers a weight saving over the ARO08 without impacting braking performance.
- ASuper Light weightAiRoTor technology taken to the limit ! 140mm 63gr ! / 160mm 68g ! / 180mm 98g!
- Excellent Heat Dissipation
- Fully Tested
- High grade SUS410 stainless steel
- Ground and Hardened to 47 HRC
Due to extreme low mass Ai2 Rotors heat-up more than heavier rotors which may adversely impact some lower spec systems during prolonged braking events. However, conversely due to the extreme low mass they also cool very fast, so with proper/normal braking consideration the heating/cooling effect can be balanced.

Léger, prix attractif, montage ok. Reste à voir à l'usage mais je n'ai pas d'inquiétude.
