The uninterrupted shifting experience of the Shimano Ultegra R8100 12-speed cassette range lets you climb, sprint, or cruise without stopping to think about your next gear change. Larger driving cogs maximize drivetrain efficiency and create compatibility with both Shimano 11 and 12-speed Freehub bodies.Refined 12 step gear combination provides peak efficiency and accelerating performance for every racing situationFaster, smoother shifts under maximum pedalling forceCompatible with new 12-speed and road 11-speed Freehub bodyLightweight 12-speed HG+ cassette with rigid alloy sprocket carrier for reduced weight and better shifting performance, even under the most demanding gear changesHyperglide+ sprockets have been designed to reduce weight with improve teeth shaping providing accurate shifting and reduced wearWide gear range to meet the demands of all types of riderFor use with 12-speed chainsHyperglide+ cassettes revolutionized off-road shifting with its seamless shifts both up and down the gear range. Now it's time for the technology to change road cycling. Even during maximal efforts up a climb or racing a friend, riders no longer need to back off to perform a shift. In any gear, Shimano Ultegra R8150 drivetrains maximize efficiency thanks to larger cogs and retain compatibility with existing Hyperglide Freehub bodies. All this while increasing to 12-gears, Ultegra CS-R8100 cassettes are the new paradigm in road shifting.

The junction is required for connection of rear mech, front mech, battery, and cable to battery indicator junction box with reliable and secure water resistant connectors. Cables sold separately.
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).
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.
