Compatibility
The SM-MA-R160D/D is intended for compatible rear Flat Mount frames and Flat Mount brake calipers.
It is not a Post Mount or International Standard (IS) adapter. Compatibility depends on the frame's brake mounting configuration, caliper design and rotor diameter.
Important Installation Information
Check Shimano's compatibility documentation and the frame manufacturer's specifications before installation. The frame must support the intended rotor diameter.
Use the correct mounting bolts for the frame thickness and follow Shimano's installation and tightening instructions. Some frame mounting bolts are selected separately according to frame dimensions.
