Shimano Ultegra R8170 C50 Carbon CL Front Disc WheelThe Shimano Ultegra R8170 C50 Wheel features a 50mm-deep full carbon tubeless ready rim with Shimano D2 rim profiling. This rim offers exceptional aerodynamic efficiency and agility while maintaining stability and control during strong cross winds. Suited to climbing sessions, long-distance fast events and epic endurance rides, this wheel features a centre lock disc rotor mount and is compatible with Shimano 11 and 12-Speed drivetrain systems.Balancing aerodynamics, weight, and affordability, the new Ultegra R8170 C50 front wheel is sure to inspire action on your group ride with its all-new tubeless carbon rim and updated, 12 and 11-speed compatible hub.Summiting climbs, carving descents, or cruising the flats, the new C50 is the jack of all trades among the new Ultegra R8170 wheel lineup. The tubeless, carbon rim features a 21 mm internal width that pairs nicely with wider, modern tyres while the HYPERGLIDE cassette body is compatible with 11 and 12-speed cassettes.Centre-Lock Disc Rotor MountThe Centre Lock system makes an easy rotor installation possible with a spline mount and a lock ring. The lock ring mounting system reduces the total working hours by shortening the amount of time of both installation and de-installation. In addition, the secure fixing by the spline mount enhances precision and rigidity while improving braking efficiency.D2 Aerodynamic Rim ProfileAerodynamic performance is affected by wind direction. To create the D2 rim, Shimano engineers considered both frontal and crosswinds, aiming to achieve optimal performance in real-world riding conditions. Extensive prototype testing, in the wind tunnel and on the road, proved that a wide rim shape with a deep tyre bed performs best across a wide range of conditions. At yaw angles ranging from 0 to 15 degrees, the Shimano D2 rim profile reduces air drag better than others aero shape rims. This rim design also boosts lateral wheel stiffness and offers improved vertical compliance for increased control, comfort and durability on the road.Shimano E-Thru Axle SystemThe tool-less type thru-axle skewer system optimizes rigidity and weight balance and enables easy operation with a reliable internal cam mechanism. The 15 mm thru-axle system is 15% stiffer torsionally and 25% stiffer in transverse shear than a traditional 9 mm quick release front axle system. High rigidity is secured while keeping the optimum weight balance. The E-Thru axle hub system minimizes the distortion of suspension while maintaining lightweight for riding around sharp corners at high speed.Features: Series: Ultegra R8100 Series Rim: Carbon Tubeless Ready 50mm height full Carbon rim Internal Rim Width: 21mm Shared rim profile with R9200 Dura-Ace wheels Improved aerodynamics Axle: 12mm E-THRU Disc Rotor Mount: Centre Lock Weight: 698gA 2-year warranty is offered with all Shimano products from Chain Reaction Cycles (3 years on Dura-Ace and XTR products).Buy Shimano Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.

Shimano Ultegra R8170 Di2 12 Speed Disc Brake - Black - Right Front}, Black
  • £449.99

Shimano Ultegra R8170 Di2 12 Speed Disc BrakeThe Ultegra R8170 Di2 12 Speed Disc Brake from Shimano is compatible Shimano Di2 electronic drivetrain systems and Servo Wave hydraulic disc brakes. This brake system offers exceptional comfort and easy-to-use ergonomics with lighter and smoother brake lever action and exceptional gear shifting accuracy in all weather conditions.Road riding has never been this much fun. That's because the redesigned Ultegra ST-R8170 Dual Control Levers have all-new ergonomics, even more precise brake modulation, and wireless electronic shifting. This trifecta lets you focus on the next sprint, the next descent, or the next joke from your riding partner. Shimano's new Ultegra ST-R8170 brake levers bring enhanced modulation and control to every ride by employing Shimano's proven Servo Wave technology. The all-new Di2 platform, used on both Dura-Ace and Ultegra, untethers the shifters while delivering the world's fastest, most reliable wireless shifting. Your time on the bike is precious, let Shimano make it even better. Servo Wave Precise Braking ControlWhen you pull a Servo Wave 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. Shimano DCL Dual Control LeverDCL stands for Dual Control Lever. It has brake and shifting functions in the system and enables easy operation. Ergonomic innovation is as critical to higher standard performance as the added gearing. The shift internals borrows the robustness from Shimano's MTB technology and is so smooth and effortless that one finger shifts front and rear are possible. Indeed, shifting is the ultimate act of Shimano Total Integration and simply has to be experienced to be understood. Features: Clean Cockpit: Electronic connection enhances the aerodynamic effect and ensures easy maintenance Unparalleled ergonomics engineering refined with pros' feedback Raised hood peak improves ergonomics Optimised brake control Lighter, smoother lever action Enhanced modulation thanks to an expanded braking control area Compatible with wired and wireless connection Available for use with additional satellite shifters High electronic energy efficiency 1.5 to 2 years of battery life with easy-to-change CR1632 shifter batteriesA 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.

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.
