This genuine Shimano front post to post (P/P) brake adaptor is essential for mounting your Shimano brakes to your post-mount fork. If your fork is designed natively for a 160mm rotor, this adaptor is necessary to space out your brake caliper from the fork for use with a larger 180mm rotor.

We recommend these adaptors as the best brake adaptors for use with Shimano brake systems. They are built from forged, anodized and machined aluminum for rock-solid and precise mounting of your brakes for optimal braking performance.

  • Mount 74mm Shimano brake calipers to 74mm post-mount forks
  • For use with 180mm rotors.

      It's exactly what it says it is--a necessary adapter to space your calipers on post-mount disk brakes to accommodate 180mm rotors. It bolts right on (even includes longer bolts with lock-tite already on them). If you put it on upside down, it won't work. I got it right on the first try, of course, but just so you know. The only way this could be better is if it were free (maybe even packed with the kind of spendy XT calipers), but Shimano has kids to feed, right?

      It works. The directions have the cupped washer in a spot that didn't make the break pad line up properly with the braking surface, so I moved it and that fixed the problem.

      For those that don't want to pay for this, you can just go buy longer screws and spacers at home depot for under $5 that will do the same thing.

            I was looking for an economical solution to install a 180mm rotor for a Hayes Ryde, this was actually a gamble since it took a little persuasion on my part to make the part fit but actually very little indeed. Up to date it has performed flawlessly.Tried to include a photo but the application is not intuitive.

                      This is a crucial part of my 180mm rotor conversion. It's sturdy, and comes with bolts, and washers to compensate for the caliper angle (you can see that the 2 bolts are spaced differently...).

                          This product worked great with my XT brakes and 180mm RT86 rotor. I know there are alternatives, but this made it so easy to line up the calipers with minimal effort and gave me confidence that the brake is installed correctly and will perform optimally. I've been riding with no issues, and I'm glad I went with this and a 180mm rotor in front.

                          I like components that come with "this way up" arrows, especially odd-ball brake parts. Nothing else to say except no problems after many hours of riding. I'm really puzzled as to why Shimano doesn't include this ... if not with the brakes, then with the 180mm rotor bought seperately.
