I've got a Surly Disc Trucker 26" frame and wanted to move the stuff from the old bike to the new frame, but it has a different mounting system. I have Avid BB7 Road Mechanical Calipers. Is there an adapter for this or have I to buy another calipers? On the Surly bike they say they have installed the TRP Spyre C.

this is called flat mount. you need a flat mount frame to post mount caliper adapter.
