Disc Brake Adapter

The Hope Disc Brake Adapter allows you to mount your Hope post-mount caliper to a variety of frame and fork configurations. Depending on your frame, fork, and desired rotor size, one of these adapters may be necessary.

The IS to Post, 160mm Rear is for IS mount frames or forks. It allows a 180mm rotor on the fork and a 160mm rotor on the frame.

The IS to Post, 203mm Rear is for IS mount frames. It allows a 203mm rotor on the rear of your frame.

The Post, 180mm Front is for post mount frames or forks. It spaces your caliper for a 20mm increase in rotor size. If your frame or fork is 160mm post mount, this adapter lets you run a 180mm rotor. If your frame or fork is 180mm post mount, it lets you run a 200mm rotor.

The Post, 203mm Front is for post mount frames or forks. It spaces your caliper for a 43mm increase in rotor size. It really only works on 160mm post mounts, allowing you to run a 203mm rotor. This adapter is not useful for 180mm post mount frames or forks.
