Shimano Claris RS305 Disc Brake CaliperThis mechanical disc brake caliper is designed for ease of use and it is simple to set up and maintain by mounting via Shimano's flat mount interface. Perfect for keeping you in control of your road bike adventures, this model features a heat management system and an Ice Technology pad within the fin. This combination reduces heat build-up and allows you to benefit from consistent braking efficiency as well as excellent longevity. Designed to offer wide pad clearance and easy tool access, this is a great upgrade for riders that want a straightforward and easy to fit brake caliper for their road bike.Features:Use: RoadCompatibility: New Super SLR Mechanical disc brakesPad Type: L02A ResinPad Standard: K02S Resin Mount: Flat mountCaliper Fixing Bolt: Bolt fix pinFixing Bolt Tool Size: 4mmIce Technologies Compatibility Caliper: YesPad Axle: Pad axlePiston: 1Recommended Brake Rotor: SM-RT54/RT56 (160mm); RT-MT800 (140mm/160mm)Single or Pair: SinglePart Numbers: Front: BRRS305F; Rear: BRRS305R Technologies:New Super SLR: SLR stands for SHIMANO Linear Response. The NEW SUPER SLR design makes use of a friction-reducing mechanism in the caliper, lever and cable that improve response and modulation. Also for the lever, the SERVOWAVE mechanism is adopted to provide quick contact of shoe to rim and longer stroke from the initial braking effect for better control. SLR is the essential factor in the SHIMANO dual-pivot caliper that deliver more braking power than conventional side-pulls.Road Disc Brake: Road Disc Brakes deliver consistent brake performance in any weather, with lighter lever action and greater brake power control for a wide range of riding styles.Ice Technologies: ICE TECHNOLOGIES piston in order to achieve optimized lightweight, high rigidity and heat dissipation. Oversized pistons transfer hydraulic power directly to the brake pad, and ceramic material is used to avoid heat transfer for constant stable braking, providing efficient stopping power transfer without loss.A 2-year warranty is offered with all Shimano products from Chain Reaction Cycles (3 years on Dura-Ace and XTR products).Buy Shimano Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
