Shimano F180P/S Disc Brake Adaptor for 180mm Rotor Info
The Shimano F180P/S Disc Brake Adaptor for 180mm Rotor is a straightforward, reliable solution for running a 180mm rotor on a flat-mount frame with a post-mount caliper — or vice versa, depending on your setup. Shimano-made and designed to integrate cleanly with the rest of their brake ecosystem, this adaptor removes the guesswork from rotor and caliper compatibility.
If you're building up a bike, swapping calipers, or upgrading to a larger rotor for more stopping power on descents, having the correct adaptor is non-negotiable. This is the one Shimano specifies for that job.
