10 firsts for the new Shimano Ultegra Di2

The latest Ultegra Di2 brings with it a number of firsts and updates for Shimano’s second-tier road groupset, including 12-speed gearing, wireless shifters, an Ultegra-level power meter option and more.

  1. Like Dura-Ace, the new R8100 series moves to 12-speed
  2. For the first time, it’s electronic-only – there’s no mechanical option
  3. Wireless disc brake shifters make for cleaner cockpits (the rim brake groupset is still fully wired)
  4. Built-in Bluetooth brings out-of-the-box tuning
  5. There’s an Ultegra-level power meter option
  6. Full carbon tubeless wheelsets
  7. Direct charging means no junction boxes
  8. Servo Wave braking technology borrowed from GRX Di2
  9. Wider rotor clearances for quieter brakes
  10. New lever ergonomics for improved braking from the hoods and shifting from the drops
