Di2 electronic drivetrains use a powerful long-life 7.4V Li-Ion battery, this charger that will keep your Di2 system shifting and keep it in top condition and ready for shifting.
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).

You can also get the more detailed bike maintenance by connecting to your bike by wire with E-Tube Project Professional application. Dual Control Lever: DCL stands for Dual Control Lever. It has brake and shifting functions in the system and enables easy operation. Ergonomic innovation is probably more critical to the higher standard performance than the added gearing. The shift internals borrow the robustness from Shimano's MTB technology and are 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. 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 the Ice Technologies piston to realise the cooling technology for consistent performance. Oversized pistons transfer hydraulic power directly to the brake pad, and ceramic material is used to avoid heat transfer for constant stable braking, providing efficient stopping power transfer without loss. This model's Ice Technologies piston achieves optimised lightweight, high rigidity and heat dissipation. One Way Bleeding: One Way Bleeding was developed for quick and easy prevention of air in the hydraulic system. Shimano has 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. Hollowtech II Technology: Providing the best balance of stiffness, strength, weight and rotating performance, the concept of Hollowtech II technology is focused on producing a superior crankset that will maximise your power transfer. The rigidity of the crankset ensures pedalling efficiency while its weight, a key element of the crankset, you want light, aids in cycling longer distances where you need to pedal more. Moreover, the Hollowtech II crankset has a high-precision sealing in the bearing area to increase durability maintaining the excellent rotating performance for long periods. Hollowglide Technology: This model features Hollowglide technology on its outer chainring. High rigidity hollow structure cuts down on weight yet maintains strength. Better power transfer and quicker and more precise front shifting. Digital Integrated Intelligence: The revolutionary DI2 shifting system solves the challenges drivetrains present to the power-delivery equation in cycling. DI2 gives you instant, accurate, lightning-fast shifts the first and every time, at the push of a button. Even in the most extreme conditions, shifting is precise and controlled. You can change gear even under heavy load while climbing or accelerating. With DI2, you are in complete control. E-Tube Project: Shimano’s E-Tube Project Cyclist application allows you to customise your bike, update firmware, and maintain it by connecting it wirelessly to your bike. You can also get more detailed bike maintenance by connecting to your bike by wire with the E-Tube Project Professional application. E-Tube Ride: Shimano’s E-Tube Ride application allows you to visualize your ride with a route map to your destination, a real time ride data display, and ride record data on your smartphone while you are on your bike. You can also upload your ride log data to Strava.

Speed: 11-Speed Links: 114 Weight: 257g Technologies: Shadow RD: Traditional derailleurs extend wider than the profile of your bike. With its low-profile design, Shadow RD is a more compact derailleur that fits closer to the frame, with more direct cable routing. Shadow RD maintains a consistent distance to the cassette for increased shift stability. The reduced body width creates a sleek and smooth appearance, ensuring less damage in a crash. Please note that this groupset does not come supplied with outer cables. Front mech support plates not included. A 2-year warranty is offered with all Shimano products.
