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.

The wider clearance of the Shimano Ultegra R8000 brake makes it compatible with larger tyre sizes such as 700x28C. The stabilizer between the axles reduces deformation and improves the braking efficiency, offering a clear contact feeling with balanced rigidity, weight and stopping power.
Excellent sealing and reliability have been proven through repeated field tests in various riding conditions, including extreme temperatures, rain, mud, and cobble stone roads. Using a hard wired battery system which is both light weight and accurate compared to current wireless technology (as a wireless system would require 4 batteries: one for the RD, one for the FD, and one for each shift lever). The use of a single small and discreet battery is light weight, efficient and creates a robust and reliable system. One charge can give between 1000 and 2000 kilometre range depending on conditions and front mech operation (as this is the main power drain).
