From the Curator:

"An upgrade often overlooked - Many enthusiasts get carried away trying to shave off every gram on a pair of hubs (in some cases, sacrificing other characteristics like hub engagement, bearing durability or spoke tension), and fail to address these two large pieces of rotational mass.

They are priced competitively, and can add a splash of colour to any wheel.
While maintaining excellent overall brake system performance, durability and cooling.

The best part, Installation is a simple - Plug and Play, it takes just 5-10 mins and can be done at home."

Ashima Disc Caliper Adapters are a quick and simple way to utilize larger rotors on your Flat Mount frame or fork.


For centerlock interface, we include a Ashima's super light weight CL-6B Lockring Adaptor which weighs just 22 grams and can be installed on a variety of axle specs - 9/10/12/15/20mm.

The Ashima AiRotor is the third lightest option from Ashima. Despite its low weight, it is ideal, even for Mountain applications. It features a low mass, single-piece stainless steel construction that is meticulously machined out of a proprietary disc-brake specific, high grade SUS410 stainless steel alloy. Each individual rotor is then precision ground on each side to ensure perfect parallelism and hardened to HRC 42 for maximum durability.

While other manufacturers integrate materials such as titanium or carbon fiber into their rotor designs, they do so at the expenses of cost and more often than not, they do not last as long as 1-piece constructions. Ashima takes a different approach, their AiRotor's weight savings comes from very aggressive and stylistic machining.

The enlarged cut-outs in the rotor act as vents which aid in heat dissipation.
No special pads are required for use with these rotors.


  • Super light weight
  • Excellent Heat Dissipation
