SHIMANO Dura-Ace BR-R9270 Rear Disc Brake Caliper

With an all-new design, DURA-ACE BR-R9270 hydraulic calipers are our most compact yet. MONO-BODY construction ensures light weight and rigidity, proving that good things can come in small packages. With an all-new MONO-BODY construction design, high performance braking has reached a new peak. The BR-R9270 caliper drops weight while also providing increased pad clearance, ensuring a quieter ride. Lastly, a new bleeding process makes maintenance easier than ever. Features: - One-piece structure maximizes stiffness and reduces weight - 10% wider pad clearance decreases the chance of rotor rub - Maintenance-friendly bleeding process Specifications: - Average weight: 120 (Front) 110 (Rear) - ICE TECHNOLOGIES pad compatible caliper: Yes - Brake hose color (kit): Black - Brake hose (Kit): SM-BH90-JK-SSR - Brake type: Hydraulic disc brake - Caliper fixing bolt_Anti loosen method: Bolt fix pin, snap ring - Caliper fixing bolt_Tool size: 4 mm - Caliper_MONO-BODY: Yes - Fixing screw spec for rear mount_10 mm mount: Yes - Fixing screw spec for rear mount_15 mm mount: Yes - Fixing screw spec for rear mount_20 mm mount: Yes - Fixing screw spec for rear mount_25 mm mount: Yes - Fixing screw spec for rear mount_30 mm mount: Yes - Fixing screw spec for rear mount_35 mm mount: Yes - Hose joint: Straight - Mount type: Flat mount - ONE WAY BLEEDING: Yes - Pad mount: Pad axle - Piston: 2 - Recommended brake lever: ST-R9270 ST-R9180 - Recommended disc brake rotor: RT-MT900 - J-Kit spec (for OEM): Yes - Oil: SHIMANO Mineral - Pad_Option 1: K04Ti Metal - Pad_Option 2: L04C Metal - Pad_Standard 1: K03Ti Resin - Pad_Standard 2: L03A Resin Technologies: Mono-Body: - SHIMANO’s MONO-BODY caliper is machined from a single cold forged block in order to maximize stiffness. A perfect balance of stiffness and weight, the MONO-BODY caliper is a component of our linear response hydraulic disc brake system. Linear response equals strong power and superb controllability. Ice Technologies: - The fade, which can occur to disc brake rotor and pad when braking on a long downhill ride for instance, has a negative impact on the braking performance. SHIMANO has adopted ICE TECHNOLOGIES disc brake rotor and ICE TECHNOLOGIES pad to realize the cooling technology for consistent performance. The clad disc brake rotor blade, which has a 3 layer-sandwich structure of stainless steel, aluminum and stainless steel, provides better radiation performance. Also, the radiation fin has been adopted for the pad. Moreover, the clad disc brake rotor blade and the radiator fin provide long pad life, less noise, less fade and lightweight. one_way_bleeding: - ONE WAY BLEEDING” was developed for quick and easy prevention of air in our hydraulic system. We have streamlined the oil route throughout the system to prevent air bubbles from being captured in the system.One way oil routing plus a funnel tool with mineral oil provides an easy and clean bleeding system.
