Hi, I'm kind of new here, and I need help: I have bought a Schwinn Homegrown, v-brake equipped bike, and I am pondering fitting disc brakes to it. In the front the Rock shox fork is prepared for this, but in the rear, the frame has this plate, with 2 threaded holes. I can not undertand the setup. Is there some kind of an adaptor needed, is there a specific caliper that needs to be used?
Thanks for any insight.
