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.

In a 160dia-Centerlock configuration with ashima adapters, these rotors shed more than 25% off common top tier rotors like DuraAce.

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

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

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 Ai2 Rotor is the world's lightest 1-piece rotor and 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.

Its low mass and unique cutouts along the mounting holes aid in efficient heat dissipation and excellent rotor cooling, allowing for more predictable braking capabilities even during long descents. No special pads are required for use with these rotors.


  • Super light weight
  • Excellent Heat Dissipation
  • Fully Tested beyond the ISO standard
  • High grade SUS410 stainless steel
  • Ground and Hardened to HRC 42
