Overview

The Avid 2019 Disc Brake Mounting Bracket is a purpose-built adapter that bridges the gap between International Standard (IS) frame and fork mounts and post-mount disc brake calipers. With a 20mm offset, it positions your caliper at the correct alignment for a 180mm rotor on the front wheel or a 160mm rotor on the rear, making it a practical solution for riders upgrading rotor sizes or fitting calipers to IS-equipped bikes.

Constructed to handle the demands of disc braking forces, the bracket comes with stainless steel mounting bolts for corrosion resistance and long-term reliability. Installation is straightforward — bolt the bracket to the IS mount on your frame or fork, then attach your post-mount caliper to the bracket. It is a small, inexpensive component, but getting the right bracket is essential for proper caliper alignment and safe braking performance.

Frequently Asked Questions

What rotor sizes does this bracket support?

This bracket supports a 180mm rotor on the front and a 160mm rotor on the rear when converting from an IS (International Standard) mount.

Does the bracket include mounting hardware?

Yes, the bracket comes with stainless steel mounting bolts for a complete and secure installation.

Is this bracket compatible with non-Avid disc brake calipers?

The bracket follows the IS and post mount standards, so it is generally compatible with any disc brake caliper that uses the same mounting interface, though it is designed and sold by Avid.

What does the 20mm IS designation mean?

The 20mm refers to the offset distance the bracket provides to adapt an IS (International Standard) frame or fork mount to accept a post-mount caliper at the correct position for the specified rotor size.
