Why We Like The Disc Brake Adapters
Whether you're trying to mount your rotor with an IS or post-mount setup, we've got the right Shimano Disc Brake Adapters for the job. All you need is the skeleton key to understanding Shimano's admittedly byzantine model naming convention. SM-MA stands for Shimano Mount Adapter, so that'll be universal across models and can be safely ignored now that you're here.
The rest of the model name is the important part. An "F" denotes the front brake and an "R" denotes the rear brake. The following number (160, 180, or 203) is, of course, the rotor size, with special parentheticals for 203mm rotor conversion. The final two initials respectively describe the caliper type and the frame/fork mount type, corresponding to either ISO or post-mount.

maybe it will work better with shimano
got this to convert 180 to 200mm sram guide RE, which has the CPS washer system, unfortunately I was unable to get the caliper height to be correct with this adapter and hardware, seemed like the pads were never really in the right spot on the rotor. I see no reason why this would not work with non CPS systems, screw you sram for your proprietary crap lol

No Install instructions
There's a QR code that's supposed to take you to the install manual but it took me to a page with various notices/warnings but no information on how to install. It's mostly straightforward, however there's one piece where I'm not sure if it's an extra part... Pretty frustrated by Shimano's QR code manuals. I'll give it 4 stars for quality but not having basic install instructions isn't great

Would one of these adapters allow me to go from 180 post mount to a 220mm (or 223mm) rotor? Maybe the 160 to 203 adapter, since the delta is the same?
