The power house of Shimano Di2 is a long-life 7.4V Li-Ion battery that is both compact and reliable, taking shifting effort away from you 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 internal 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) 500 times rechargeable life Internal chip enables system wireless functionality of Bluetooth components Battery is to be mounted with seatpost or frame/fork manufactures hardware normally inside the seatpost or seat tube/fork steerer Reliable and secure water resistant E-tube terminals connection Charging is done via stem junction or handlebar display Battery weight is 50 grams

With several years of development and working closely with professional teams you can expect extreme accuracy from Shimano's first fully integrated power meter HollowTech II 12-speed Dura-Ace chainset Accurately calibrated strain gauges are integrated inside both left and right crank arms, this provides a stable measurement system through rotation from both sides for extremely precise data +/-2% accuracy of strain gauge measured power Bluetooth and ANT+ with wireless firmware update and data acquisition system Easily rechargeable integrated battery with fully waterproof reliable electric system Hollow outer chainring, giving vast improvements in rigidity and increased weight savings The hollow outer chainring has essentially removed outer chainring flex, hugely improving shift performance making it precise even under high load These industry leading HollowTech II cold forged hollow crank arms have evolved to increase rigidity, reduce weight, and improve strength The teeth have been developed to work only in conjunction with the 12-speed chains for improved contact providing more efficiency and improved power transfer There is a wide range of chainring ratios and crank arm lengths available enabling customisation for all riders and racing disciplines HollowTech II integrated bottom bracket design uses a wider bearing placement and larger axle diameter for increased stiffness and efficiency Bottom bracket seal design has a minimal bearing interface gives superbly smooth rolling and increased durability
Shimano’s Ultegra range is race focused, but at a more affordable price than the top-tier Dura-Ace line. The R8000 offers 11 sprockets and is available in a broad range of ratios, so whether it’s a tightly packed 11–25-tooth block for time trialing or a wide ranging 11–32-tooth for conquering even the most epic climbs, there’s something for everyone. Tough, Lightweight, Durable Machined from a combination of aluminum and steel, an Ultegra R8000 cassette offers an excellent compromise between weight, durability, and performance. To keep the weight down aluminium is used to rivet the largest three sprockets and a fibre-reinforced composite the next largest two. Tipping the scales at a low of 232 grams for the 11–25T, and a high of 300g for the 14–28T option, regardless of your preferred choice you certainly won’t be weighed down. But, not only is this cassette lightweight and high performing, it is also durable. Corrosion resistance comes via the nickel-plated steel sprockets, so you can ride without the worry your cassette will disintegrate at the sight of rain. A Shift In Performance Aside from weight and durability, the R8000 cassette performs its job well. In fact, there’s virtually an imperceptible difference in performance between it and a higher-spec’d Dura-Ace cassette. Shifting gears is exactly what you’d expect from a component maker as known for precision engineering as Shimano, in one of its top-tier products. It’s quick, smooth, and reliable. Hyperglide technology, the brand’s proprietary system, ensures that even under load you’ll be able to change through the gears. Product Features Lightweight 11-speed HG-EV cassette with rigid alloy sprocket carrier for reduced weight and better shifting performance, even under the most demanding gear changes Hyperglide EV sprockets have been designed to reduce weight and improved teeth shaping provides accurate shifting and reduced wear Wide gear range to meet the demands of all types of rider Optimised for use with 11-speed HG-EV chains, but compatible with all 11-speed drivetrains Please note, due to the current supply situation with many products, aftermarket packaging and manuals may not be supplied. Manuals can be downloaded from si.shimano.com and we advise that any work carried out on your bicycle is done so by a Shimano Approved Service Centre
