Shimano Disc Brake Adapters reviews and deals for sale

Exact fit

Purchased to go from 160 to 203 post to post. No washers needed other than what came with it. Beat on the bike and it holds alignment just fine

Fits as advertised - easy to use

Not a ton to write - the adapter is easy to install, true to size and easy to dial in, stays dialed in, and reasonably priced. It's very straightforward - kind of like getting an A on a first grade spelling test, but hey, it's an A.

Adapter, bolts and no washers.

I ordered this to mount my Shimano M8020 caliper to my front fork paired with a 203mm rotor. The packaging includes the adapter, and 2 mounting bolts. BEWARE; no cup and cone washers are included. I feel that the washers should be included but understand they are not necessary. Wish they were more clear about what’s included in the packaging. 4 out of 5 starts because the washers… read more should be included. The washers came with my rear adapters.

203mm brakes on RM Instinct

I loved my X2's with 180mm rotors, but I wanted more braking power without spending $500+ dollars for 4-piston brakes. So I did what a lot of people do in my situation and bought big ol' rotors and some adapters. For $100, I picked up rotors and adapters and I now have a noticeable increase in power while keeping the brake set I love. As others have said, the part numbers are… read more very confusing, so hopefully these photos will clarify what's needed for 160mm and 180mm post mount applications. Sidenote: I was advised to avoid the Hope 203mm two-piece rotors on the Fox 34 due to clearance issues. I'm glad I chose the one-piece. It's a very tight fit but they clear, and they're about $15 less. Stoked!

Shimano brake disc adapter 160 to 203

Part # SM-MA-F203 (160mm to 203mm), Post/Post Front/Rear Mounted Hope X2 brakes with Hope one-piece 203 rotors on my Fox 34 (160mm post mount ) fork. I recommend one-piece rotors on the Fox 34 to avoid clearance issues. It's a tight fit.

Perfect.

Got some to make my ripmo 203 F/R. Some pictures don't actually match what you're getting.

Works with SRAM Guides

Used this for a hardtail build. The profile worked well with the shape of the SRAM Guide RSC calipers.

As Expected

Does its thing and does it well. No complaints for this here.

Part works great, Part #'s not so much

If you need it you need it. Simple adapter to hook it up. Hit us up if you have any questions on the application for your bike.

For forks with 180mm mounts

My fork has 160mm mounts so this one doesn't work for using a 203mm rotor.

A must.

Shimano's part numbers can be confusing. Be sure to hit the "Chat Now" button to get help from a Gearhead who can help confirm the correct adapter for your frame.

I noticed all options above include IS attachment, EXCEPT the pic of the "203 front" which appears as a post mount adapter for 8" remaining 74mm; such as all new shimano brakes are. BIG QUESTION: if I order the 203 front will I receive the 74 to 74mm, and excuse the IS designation (the photo goes with this selection, i believe). Thanks!!
