Hope Mount K Brake Adapter

The Mount K adapter is specifically engineered to bridge the gap between post-mount calipers and post-mount frames, allowing you to run a 160mm rotor on a frame or fork designed for a 140mm post-mount setup.

Yes, every Hope Mount K adapter includes the necessary mounting bolts, so you have everything required to secure your caliper to the frame right out of the box.

This adapter is machined from high-grade T6 2014 alloy, which provides a superior strength-to-weight ratio compared to cast or lower-grade aluminum alternatives. It ensures precise alignment, which is critical for preventing brake rub and ensuring consistent, reliable stopping power.

No, this adapter is strictly for post-mount to post-mount configurations. It will not work if you are trying to adapt an International Standard (IS) mount to a post-mount caliper.

Yes, the adapter is directional. Ensure the 'up' or orientation markings are facing the correct way to align the caliper properly with the rotor; if the caliper feels misaligned or the pads don't sit flush against the rotor, double-check that the adapter isn't flipped.
