What sets the Shimano adapter apart

Shimano is a renowned manufacturer of bicycle components, known for precision and durability.

This adapter is particularly suitable for mountain bikers and e-bike riders who want to mount large brake discs (203 mm) on their bicycle. It is also ideal for custom builds and conversions where a Postmount caliper needs to be adapted to a frame without direct mounting.

1. Remove the existing brake caliper and clean the mounting surface.
2. Place the adapter on the frame mount and align it.
3. Attach the brake caliper to the adapter and tighten all screws to the recommended torque.
4. Check the alignment of the brake disc in the caliper and adjust if necessary.
