Uberbike flatmount disc brake adapters make it possible for you to change your disc brake rotor size on the rear of your frame. This adapter allows the use of a 180mm front disc brake rotor with a post-mount caliper and a flatmount fork. Note that this adapter adds +40mm, so is compatible with flatmount forks using a 140mm native mount with a 180mm rotor. If your fork uses a native mount size of 160mm, to run a 180mm rotor, you would need the following adapter HERE
