Description of ASHIMA ARO-09 Ai2 Brake Disc 6-hole - rot

Ai2 - one of the lightest 1pcs. stainless steel rotor.

Some said AiRoTor 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 AiRoTor the bestselling aftermarket rotor of all time . Well they were wrong and Ai2 proves it!

Ai2 offers a staging 23% weight saving over the AiRoTor without impacting braking performance.

Specifications of the Ashima Ai2:
  • Super Light weight (160mm/ 66g, 180mm/ 93g)
  • High grade SUS410 stainless steel
  • Grounded 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.

Meelis May. 29th 2017

Poor braking quality and short disc lifetime.

Anonymous May. 29th 2017

After some use the disc started to eat brakepads, making 2 furrows.
Horrifbe little vibration when using brake.
Minimal braking surface dies after second pads.
Light weight is not for brakes!

sehr gute Bremsleistung, sehr leise, P/L top, bin begeistert!!
Lieferung und Service von Bike24 mal wieder absolut TOP! wollte mir ja zuerst die Dartmore Nano's (made by Ashima) ans Rad basteln doch leider war (ZUM GLÜCK!!) nur noch 1ne lieferbar. Liefertermin laut Hersteller unbekannt. mh naja, hab dann telefonisch meine Bestellung auf diese Ashima Ai2 hier geändert. zum testen hab ich sie (nebst nagel neuen Shimano Resign Pads) erstmal an meinem HT montiert. hatte die Hoffnung auf "quietschfreie" Scheibenbremsen eigl schon aufgegeben.. dann heute O.o der absolute Brüller! die Dinger sind ruck zuck auf Betriebstemperatur (selbst wenns nur nen Grad über 0 hat), bremsen absolut traumhaft und sind vor allem LEISE! scheuern super ab, big thx B24!! :D
