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.

Prepared for intense mountain bike rides, this disc brake features a hard-wearing aluminium construction. This makes it more than capable of handling all the abuse that's associated with all-day epics in the mountains. Coming equipped sealed cartridge bearings, this disc brake offers incredibly smooth operation while also remaining protected from corrosion. This enables you to enjoy its superior strength and control in all-weather conditions, without worrying about the bearings being damaged. Adjustable MTB Disc Brake Engineered for ease of use, this MTB disc brake is kitted out with an adjustable lever reach. This allows you to easily fine-tune the distance between your handlebar and the lever for a more customised braking feel. As a result, you'll benefit from its brake lever which perfectly matches your hand size, riding preferences and the terrain conditions. This makes the Hayes Dominion A4 Disc Brake an ideal choice of upgrade for riders who want greater flexibility on the most demanding MTB trails. Please note: This model does not come in aftermarket packaging.
This stunning model is ideal for pro-level racing as it is for providing unmatched braking performance in your local XC rides and demanding trail sessions. Additionally, its XTR system has always led by example, showing how great a single MTB brake caliper can be and increases on this performance-level, super-lightweight and reliability every season.

They have the braking power to deal with the higher speeds, more aggressive use, and the added weight of your power assisted trail conquering weapon. Guide RE brakes feature a 4-piston caliper taken from SRAM's Downhill range and use the heat-resistant DOT 5.1 brake fluid, which prevents brake fade on those long descents. Special Features: Contact Point Adjust, Piggyback Reservoir, MatchMaker X compatible Technology Highlight(s): TPC™ Plus, DirectLink™, DOT 5.1™ Pad/Holder: Top-loading Intended Use: E-MTB System: Open System Tri-Align Caliper Positioning System: No Tool-Free Pad Replacement: Yes Stainless Hardware: Yes Technologies: DirectLink™: SRAM’s DirectLink lever design produces a solid, positive feel the second you squeeze the lever to engage the brake. It offers a no-nonsense solution to give you precise control. MatchMaker and MMX Compatible: Save weight and clutter on the bar with Matchmaker. It holds Avid levers, SRAM® triggers, and various RockShox® controls, all with one tidy, light, clamp-a dream come true for handlebar component footprint conservationists the world over. Available in two versions: Matchmaker™ X integrates the RockShox®XLoc and is compatible with XX and X0 brakes. Standard Matchmaker™is also available and works with any split-clamp design and RockShox® PushLoc. PiggyBack™ Reservoir: The brake fluid reservoir on SRAM’s latest lever design is optimised for both performance and ease of use. The PiggyBack Reservoir offers a simple, failsafe way to manage brake fluid, and also allows for ambidextrous lever placement-so you can switch your levers on the handlebar and run them moto style without hassle. Reach Adjust: Brake lever fit and feel is a personal thing. Riders have individual positioning preferences, as well as unique hand sizes and finger lengths. Reach Adjust makes it easy to adjust your lever for maximum one-finger control for everyone. TPC Plus™ (Timing Port Closure): A hydraulic brake’s timing port is the connection between the reservoir and the master cylinder bore. When the lever is squeezed, a cup seal passes this area and closes the port to pressurise the system. SRAM’s new timing port closure system, called TPC Plus, features durable seals and an ultra-smooth cylinder bore finish producing dependable braking power and consistency. DOT 5.1™: Heat is an enemy of any brake system, so advancements in heat management mean advancements in your ride. SRAM found that DOT 5.1 takes almost three times longer to boil than DOT 4, thus allowing flawless, fade-free performance in even more extreme conditions.
Enjoy a more controlled ride as you dominate around the mountain and weave between the trails thanks to this models superb four-pistons. With a faster piston retraction as opposed to its previous model, this latest version delivers superior modulation and improved braking performance, so you can get the most out of every ride. In addition, its four-piston design also reduces disc brake rotor wobbling noise and increases its stopping power by 10% when compared to the BR-M8020 caliper. Complete with N03A resin brake pads with Ice-Tech cooling fins, you'll benefit from out-of-this-world stopping power, even on the rowdiest trail conditions.
