With an all-new design, Dura-Ace BR-R9270 hydraulic calipers are the most compact yet. The 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. Durable, Lightweight and Stylish Caliper 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 Brake Fade Technology The fade, which can occur to the 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, aluminium 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. Easy and Efficiency One Way Bleeding Brake Maintenance “One Way Bleeding” was developed for quick and easy prevention of air in our hydraulic system. Shimano has streamlined the oil route throughout the system to prevent air bubbles from being captured in the system.
This mountain bike (MTB) hydraulic disc brake is equipped with a high-quality carbon lever blade with a forged aluminium lever body and caliper, which gives it a perfect balance of strength and durability without weighing down your ride with unnecessary weight. Coming kitted out with more caliper stiffness and an updated pad compound with bite, it also includes many of SRAM's finest technologies, so it's ready to deliver dependable performance wherever your next adventure takes you. Every trail and every rider is unique. To meet the infinite variables SRAM created the G2: powerful, consistent, reliable. SRAM obsessed over heat management, modulation, materials and design. They made lever-reach and contact points adjustable to fit every hand. And they tested the whole system to ensure it delivers confidence-inspiring performance and control, every ride. For the Ultimate, SRAM held nothing back. Its engineers sculpted the finest materials using titanium and carbon fibre to make this the brand's lightest four-piston brake ever. Power, modulation and lever feel set a new standard. Personalisation is quick and intuitive. And for performance, its test riders didn't dub it the "Mini-Code" for nothing. Additional Item Top Features: Number of Pistons: 4 Recommended Rotor Type: 1-piece CentreLine Rotor Compatibility: Front Option: 200mm; Rear Option: 180mm Rotor Included: No, available separately Clamp Included: Yes, MMX Clamp Hose Routing: Adjustable banjo Contact Adjust: Yes Caliper Construction: 2-piece Caliper Bleed Port: Bleeding Edge Hydraulic Fluid: DOT 5.1 Lever Pivot: Bearing Reach Adjust: Tool-free Hose Length: Front Option: 950mm; Rear Option: 2000mm Included: x1 Brake lever, x1 caliper and x1 MMX clamp (rotor/bracket sold separately) Single or Pair: Single Technologies: Bleeding Edge: With this revised caliper fluid circuitry, the bleed port has been moved to the bottom of the caliper, and all four piston bores can communicate. This way, during bleeding fluid naturally fills the caliper, resulting in an easier, more consistent bleed. Contact Point Adjustment: Some people like the instantaneous power of a short lever throw. Others prefer the feel of a longer throw. With Contact Point Adjust, you can pick the position you want your fingers to be in when your brakes are engaged. It’s a quick and easy way to customise the feel of your brakes without having to move the pads. It’s also a way to balance both brake levers to feel exactly the same. Lever Pivot Bearings: Precision sealed bearings at the lever pivot enhance the clean, crisp lever actuation and consistent, light, one-finger feel. Power Reserve Geometry: Your fingers pull in a straight line, but brake levers move in an arc. Bottom line: Your fingers typically want to slip off the ends of the levers as you pull. SRAM designed all of its brakes with the industry's lowest X Factor (that's the distance from the centre of the handlebar to the centre of the lever's pivot). That reduces the lever's inward travel, creating an arc that's closer to your fingers' natural motion and more power is delivered to the brake lever. And, the cool part is, every SRAM and Avid brake lever has it. S4 Lightweight 4-Piston Caliper: The S4 Caliper features four Machined and Moly-coated aluminium pistons for consistent rollback and easy set-up, Heat shield insulation and Bleeding Edge porting and adaptor technology for easy bleeds. Swinglink: Squeeze a SRAM brake lever and you notice it immediately. Less deadband. More positive engagement. A new cam system requires less lever throw to push the pads toward the rotor. That’s great, but there’s more to perfect braking performance than just power. You need control. Many brake systems minimise deadband—but at the cost of modulation. SwingLink solves that with its special cam shape. When the pads contact the rotor, the leverage rate curve is flat and smooth, avoiding that “on/off” brake feel. It’s the perfect balance of power and precision. Timing Port Closure: A hydraulic brake’s timing port is the connection between the reservoir and the lever cylinder bore. When the lever is squeezed, a cup seal passes this area and closes the port, which pressurizes the system. SRAM’s timing port closure system features durable seals and an ultra-smooth cylinder bore finish producing dependable braking power and consistency. Mini-Code Power: Code set the benchmark for braking power — and won a few championships, too. G2 brings it to the trail. SRAM call it “Mini-Code.” Manufacturer's Part Numbers: 00.5018.160.000 Polar Grey 950mm Front RH 00.5018.160.001 Polar Grey 2000mm Rear LH 00.5018.160.002 Gloss Black 950mm Front RH 00.5018.160.003 Gloss Black 2000mm Rear LH 00.5018.160.004 Multi Black/Rainbow 950mm Front RH 00.5018.160.005 Multi Black/Rainbow 2000mm Rear LH
The new XTR M9120 Brake Caliper is equipped with 4 pistons and boasts a high-end aluminium construction which uses an exceptionally high rigidity brake line. Whether you're a pro-level racer or wanting to boost your performance on your local XC rides, this stunning brake caliper provides unmatched braking performance on even the most demanding trail sessions. To top it off, this performance-level brake caliper is super-lightweight and reliable on every session.
The powerful Shimano XT M8120 mountain bike (MTB) brake includes a rider tuneable lever and four-piston caliper for outstanding stopping power as you navigate around the trails. Its caliper decreases rotor wobbling noise and increases its braking power by 10%, so you'll enjoy a quieter and more precise braking set-up. In addition, its lever enables combination with I-Spec EV gear shifters for an action-packed cockpit layout. There's also an adjustable reach that suits any hand size, type of riding and individual rider preferences. This is a perfect choice of upgrade for dominating every descent and shredding around the trails in style. Technologies: Servo Wave Action: When you pull a Servowave brake lever, initial pad travel is fast, so little lever movement is needed to bring the pads into contact with the rotor. The power multiplication factor then increases rapidly at the pad-to-rim contact so more of the lever stroke is used to apply greater braking power with improved control. Reach Adjust: The brake lever is equipped with a reach adjust mechanism. The distance from the handlebar grip to lever can be adjusted to suit any hand size, type of riding and individual rider preferences. Ice Technologies: The fade, which can occur to disc brake rotors and pads when braking on a long downhill ride, has a negative impact on the braking performance. Shimano has adopted Ice Technologies disc brake rotor and Ice Technologies pad to realise the cooling technology for consistent performance. The clad disc brake rotor blade, which has a 3 layer-sandwich structure of stainless steel, aluminium and stainless steel, provides better radiation performance achieving from 400˚C to 300˚C surface temperature. 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. Four Piston: Disc brake system with the dual diameter opposed-piston caliper design has differently sized pistons in front and in the rear. The system adopts a power transfer system in which the disc brake rotor is pressed by the smaller sized piston at the entrance of the disc brake rotor intake and also by the more powerful larger sized piston at the back. This prevents the wobbling motion of the disc brake rotor and reduces noises significantly. The 4-piston caliper also allows a wider contact area for the disc brake rotor while keeping the size compact, and the efficient location of pads is adjusted as necessary to stabilise the pressure. In combination use with the Servowave lever it provides an incredible 50% more stopping power than the previous model. The advanced Saint/Zee disc brake system, which adjusts to accommodate the different braking styles of different riders, offers stable braking power and excellent modulation. One Way Bleeding: One Way Bleeding was developed for quick and easy prevention of air in Shimano's hydraulic system. Shimano has 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. Click here to view the Shimano Brake Reference Guide.
