    Details

    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.

    Upgrade to 180

      I recently installed new rotors on my Santa Cruz Tallboy LTC. After riding a friends bike which had 180mm rotors front and rear, I decided I'd do the same. It's made a noticeable difference for sure. I got the Post for the front and the ISO option for the rear. Just a heads up sometimes ISO is referred to as IS.

      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.
