Product Description The Shimano BR-RS305 Brake Caliper - Flat mount and mechanical Shimano BR-RS305 is a flat mount brake caliper that is controlled mechanically, i.e. via a cable. It blends beautifully with the overall look of your road bike and, thanks to Ice-Tech heat dissipation (when using the appropriate rotors and pads), delivers sustained braking performance even under difficult conditions. At the same time, the New Super SLR System ensures optimal dosage. BR-RS305 comes with a pair of resin brake pads with cooling fins as well as (in the front version) an adapter for 140 and 160 mm brake rotor mounting.
