BR-R317

Brand: Shimano

The BR-R317 is a cable-actuated disc brake caliper that Shimano catalogues outside its named road groupsets. It has a single piston and a post-mount fitting, and Shimano rates it as NEW SUPER SLR, the short cable pull used by its road levers; the recommended lever is the Claris-level BL-R2000. Resin BP-G05A-RX pads slide onto a pad axle and Shimano recommends a 160 mm SM-RT54 or a 140 mm RT-CL700 rotor.
