SRAM G2 RS Disc BrakeAll set for hitting your local mountain bike (MTB) trails, this hydraulic disc brake is equipped with a robust aluminium lever body and a forged aluminium caliper, which makes it ready for the most demanding of trail adventures. Another highlight is its tool-less adjustable lever reach that allows you to easily set it up to match your hand size or riding style. This makes it comfortable to pull as you dive into corners and drops at speed, while also keeping your momentum flowing. Coming complete with SRAM's Bleeding Edge technology, this model also allows for simple DOT 4 fluid installation and maintenance when required.Hydraulic Disc Brake with SwingLink TechnologyWe spend a lot of time obsessing over feeling, and SwingLink technology brings SRAM's best research and development to life. The G2 RS offers riders the joys of SwingLink — getting brake pads to the rotor fast, then moderating pressure with smooth modulation. It's one small movement for your finger, one monumental upgrade to your braking.Power Reserve GeometryYour 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.Bleeding EdgeWith this new 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.S4 Light-Weight 4-Piston CaliperThe all new 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 adapter technology for easy bleeds.SwingLinkSqueeze 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 minimize 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.We spend a lot of time obsessing over feel, and SwingLink technology brings SRAM's best R&D to life.

Clarks M3 Hydraulic Disc Brake SetBuilding on the success of its popular M2 hydraulic disc brake, Clark has made several updates and refinements to bring you its powerful M3 model. Constructed with a cast alloy for the radial-type brake lever and the calipers, it doesn’t just look good, it’s much lighter than previous models too. Suitable for everything from aggressive downhill to leisure riding, its design prevents heat build-up for fade-free braking on long descents. Also, although this mountain bike brake may just have the standard two pistons per caliper, its larger brake fluid capacity brings you a braking power increase of 25% over the M2 model.Features: Radial style flip flop lever design Cast alloy lightweight design Removable handlebar clamp Reach and bite point adjustment High-quality anodised finish One-piece caliper design Pair of brakes Brake Oil Type: Mineral oil Caliper Mount Type: Post Mount and IS compatible Rotor: 160mm (included) Weight: 224g (approx, per brake) Manufacturer Reference Codes:160mm Rotor, Front & Rear: M3-F&R-160; 180mm Rotor, Front & Rear: M3FR180BAMUK-OBuy Clarks Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

This disc brake features a robust aluminium construction, which allows it to handle all the abuse that comes with blasting across the mountain at speed. Shimano has also equipped this version with an adjustable lever reach, which means that it perfectly matches your riding style, personal preferences and the terrain conditions. Technologies: 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 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. 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.
For these Campagnolo Chorus Skeleton dual pivot brakes, the compounds that are used yield superior braking performance and the lightened pad holders make pad replacement fast and easy.

It offers a no-nonsense solution to give you precise control.DOT 5.1: Heat is an enemy of any brake system, so advancements in heat management mean advancements in your ride. SRAM found that in their systems DOT 5.1 takes almost three times longer to boil than DOT 4, thus allowing flawless, fade-free performance in even more extreme conditions.Expandable Bladder: SRAM's new brake lever design includes a reshaped bladder that helps regulate and reduce air bubbles. The bladder is specifically shaped to evacuate air from the lever and push the fluid exactly where it's needed. The result is improved backpressure relief, which produces dependable braking power and consistency.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.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.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, which pressurises the system. SRAM's new timing port closure system features durable seals and an ultra-smooth cylinder bore finish, producing dependable braking power and consistency.Buy SRAM Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
