Product Information

Full details

The Hope Brake Mount J is an essential upgrade for mountain bikers looking to run modern post-mount calipers on older International Standard (IS) fork configurations. Designed for front-wheel applications using a 183mm rotor, this mount is perfect for riders upgrading their braking performance while maintaining structural integrity. A key caveat is that it is strictly intended for Hope post-mount calipers only and is not compatible with older IS-style caliper systems.

FAQs

Can I use this mount with non-Hope calipers?

This mount is specifically designed for Hope post-mount calipers and may not provide correct alignment for other manufacturers.

Is this mount compatible with 160mm or 203mm rotors?

No, the Mount J is specifically engineered for 183mm rotor configurations.

Can I use this on the rear of my bike?

No, this specific mount is designed exclusively for front fork applications.

Does it come with the bolts needed to attach it to the fork?

Yes, all necessary mounting bolts are included in the package for secure installation.

What brake models is this compatible with?

It is suitable for the Hope Tech X2 and Tech M4 brake ranges, including newer Evo variants.

Troubleshooting

Brake pads are dragging on the rotor

Check that the mount is flush against the fork tabs and ensure the caliper is correctly aligned. Use thin alignment shims if necessary to center the caliper over the rotor.

Mounting bolts feel loose

Verify that you are using the provided high-strength steel bolts and apply a small amount of blue thread-locking compound if you experience persistent loosening.

Pros and Cons

Pros

  • High-quality CNC machined aluminium construction
  • Easy conversion from IS forks to modern post-mount calipers
  • Lightweight and durable design
  • Compatible with a wide range of Hope Tech brake systems
  • Includes all necessary mounting hardware

Cons

  • Not compatible with older IS-style calipers
  • Limited to specific 183mm rotor size
  • Requires specific fork tab alignment

Setup, Compatibility & Care

To install, first ensure your fork is equipped with standard IS tabs. Align the Hope Mount J against the fork tabs and secure it using the provided bolts, ensuring you do not overtighten during the initial mock-up. Attach your Hope post-mount caliper to the bracket using the standard caliper mounting bolts. Always check for proper rotor clearance before riding; if the caliper does not sit perfectly centered over the 183mm rotor, use standard thin shims to adjust the lateral position. Regular maintenance involves inspecting the mounting bolts for signs of vibration-induced loosening after every few rides and cleaning the interface between the fork and the mount to prevent debris accumulation.
