Strummer Post Mount Disc Brake Adaptor PM-180 / PM-203
The Strummer Post Mount Adaptor is a disc brake caliper adaptor for a Post Mount setup. This product is used to adjust the caliper position to match the rotor size being used.
This adaptor is installed between the Post Mount frame/fork and the Post Mount caliper. Therefore, the frame or fork used must have a Post Mount mount, and the brake caliper must also be the Post Mount type.
