Shimano XTR Post Type Caliper Adapter

Yes, these adapters are designed to work with any standard post-mount caliper, regardless of the brand, provided the mounting interface matches the post-mount standard.

Conical washers allow for micro-adjustments during installation. They ensure your caliper sits perfectly parallel to the rotor, which is essential for eliminating brake rub and achieving consistent stopping power.

Yes, front and rear adapters are typically geometry-specific because of the different mounting positions on your fork versus your frame. Always verify the specific mounting standard of your bike frame and fork before purchasing.

These adapters are specific to the rotor size you intend to run. You must select the adapter that corresponds to your desired rotor diameter, such as 160mm, 180mm, or 203mm, to ensure the caliper is positioned correctly.

Because these are constructed from XTR-grade alloy, they are noticeably lighter than standard steel or lower-tier aluminum adapters. While the weight savings are incremental, they are a preferred choice for riders looking to shave grams off their high-performance builds.
