### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Awesome design
  

*by D***R on Reviewed in the United States on December 28, 2023*

This adaptor worked perfectly on my 200mm rotor post going to a 220mm rotor. I use SRAm brakes, and although it’s not shimano, it still works wonderfully.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Great quality and Easy install
  

*by M***. on Reviewed in the United States on December 26, 2023*

I thought I’d save a few dollars and get a disc brake adapter to go up from 160mm to 180mm brake system. What I should’ve done was spent the extra few dollars for a quality Shimano brake adaptor. I originally bought an aftermarket adaptor with two caliper bolts. I spent nearly 30 minutes trying to get the adaptor to not change position when tightening down the two caliper bolts. When it shifted it would cause the rotors to rub on the pads. I instead ordered this Shimano disc brake adaptor and had it adjusted and bolted on in less than 5 minutes. The conical spacers that comes with the Shimano made the install a breeze.  Highly recommended.

Needed to adapt a 180mm rotor to 160mm fork Posts. Used with a Shimano MT200 Hydraulic Caliper over a Shimano XT RT-MT800 180mm Rotor.
