Shimano Ultegra R8170 Disc Brake CaliperThe Ultegra R8170 Disc Brake Caliper from Shimano is the ideal flat-mount hydraulic disc brake caliper for high-performance all-weather braking power and control. Offering exceptional all-condition braking, easy maintenance and hassle-free brake bleeding, this Ultegra caliper is durable, stylish and powerful.To the delight of riders and mechanics alike, the new Ultegra BR-R8170 caliper delivers enhanced modulation, a quieter brake system, and an easier than ever bleed process. The Ultegra R8170 disc brake caliper brings a new level of control to the road cycling world with enhanced modulation and a quicker initial braking point. Despite its smaller construction, the system is quieter than ever and easier to maintain. ICE TechnologiesThe 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. 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. Features: Series: Ultegra R8100 Series 10% wider pad clearance decreases brake noise Maintenance-friendly bleeding process Type: Hydraulic disc brake Hose Joint: Straight Mount Type: Flat mount Recommended Brake Lever: ST-R8170 Weight: 146g (Front); 136g (Rear)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.
SRAM G2 RSC Disc BrakeReady for hitting your favourite trails, this MTB hydraulic disc brake features a robust aluminium lever blade that provides durable and dependable braking operation on the toughest of rides. SRAM has also equipped it with a lightweight four-piston S4 caliper that uses four machined and moly-coated aluminium pistons to achieve consistent rollback and easy setup. In addition, its calipers heat shield insulation, Bleeding Edge porting and adaptor technology delivers easier bleeds. Coming kitted out with steel-backed organic brake pads, this model offers powerful braking modulation and control as you navigate your way around the mountain.Adjustable MTB Hydraulic Disc BrakeG2 RSC is the half-ton pickup truck of the mountain bike brake world — dependable, go anywhere, do anything, plenty of power when you need it, and all of the features you need. The G2 RSC is based on the SRAM Code design, so it puts Code-like power and modulation into a mini-Code package. And of course, the signature Guide lever-feel and contact-point adjustability ensure that this brake works great for every rider. The G2 RSC presents a rider-controlled offering with an alloy blade, lever pivot bushings, stainless steel hardware.S4 Lightweight 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.Useful reach and contact point adjustments for every type of rider. SRAM design its brakes to give each individual rider distinct control of their ride.Added stiffness in the caliper and a new pad compound that offers more bite and really delivers the Mini-Code feel.Engineered for easy installation.Features: Lever Blade Material: Aluminium - Stamped Piston Material: Phenolic Plastic Pad Type: Steel-backed Organic Use: Mountain Bike (MTB) Brake Type: Hydraulic disc brake Number of Pistons: 4 Recommended Rotor Type: 1-piece CenterLine (available separately) Recommended MMX Clamp: Stainless bolt, blk clmp (available separately) Single or Pair: Single Weight: 248gPlease Note: This brake is designed for use with a Matchmaker clamp (combined with shifter) so does not come with its own bar clamp. These bar clamps are sold separately.Technologies: 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 customize 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. 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. We designed all of our brakes with the industry's lowest X Factor (that's the distance from the center of the handlebar to the center 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. 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.Buy SRAM Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
