The Shimano BR-RS305 disc brake caliper is operated by a mechanical cable pull. Compatible with all road bike frames featuring Flat Mount disc brakes, which is the standard for all frames.
Compatible with 140mm and 160mm disc diameters. For a 140mm fit, the caliper mounts directly onto the rear dropout. For a 160mm disc setup, the caliper must be mounted on an adapter available on our website to increase the mounting capacity from 140mm to 160mm.
The BR-RS305 caliper is fitted with L05A ventilated pads for improved heat dissipation, ensuring better braking performance throughout your ride.
