Shimano SM-MA90 Disc Brake Adapter $14.95
With the SM-MA90 Disc Brake Adapter, Shimano has taken an artful leap at the lowly disc brake adapter. Not only is it lighter than their older adapters, but it's more refined -- this refinement being the reason for its lightness. Where Shimano's older adapters were blocky, this one has curved edges. Where they were solid, this one has a window machined out of the center of the adapter body.
The Shimano SM-MA90 Disc Brake Adapter is available in five versions to fit 160 and 180mm rotors for front ISO or Post mounts and rear ISO mounts.

Fits Avid brakes
- Familiarity: I've put it through the wringer
Bought this to install a Avid Elixir 9 Trail front caliper on a post to post mount using a 180 Rotor. Fits perfectly! Avid for some strange reason does not sell a 180mm adapter, but only provides them on complete bikes.
Will this adapter work with shimano xt...
Will this adapter work with shimano xt brakes on a Fox float RL fork (with post mount). Trying to put on a 180mm rotor but want to make sure i get the right adapter. Thanks.
