Ashima AiRotor Lightweight Disc Brake Rotor (140) CX

The Ashima Airotor 410 six-bolt disc brake rotor is targeted at the serious weight weenie and is the lightest on the market. It is ideal for the cross country rider looking to shave every possible gram for race day.Super light and ultra durable, this 41 stainless steel rotor weighs in at only 68 grams for the 140mm.

The AirRotor design is unique to Ashima and has been double ground for superior flatness. It has excellent performance and heat dissipation in both wet and dry weather.

They’re ideal to reduce rotating weight on kids bikes, providing strong braking for Cyclocross, Road, Triathlon & MTB XC. They are not intended for Downhill use.

Some said AiRoTor would never work….then 3 years and several World Championships later. This is AiRoTor technology taken to the limit!

Caution: Due to extreme low mass AiRotors 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.
