Description

The Shimano Ultegra Di2 groupset goes to 12 speeds! The new groupset is 100% performance oriented and even faster. Whether you're racing in regional races, trying to beat your personal best or just riding for fun with friends, the 12-speed Ultegra groupset offers unrivalled control and comfort, all day, every day.

  • A sleeker cockpit

The sleek, wireless cockpit provides simplicity, clean looks, improved ergonomics and easier maintenance. The new wireless system makes shifting gears faster, without compromising accuracy and reliability.

  • Fast, continuous shifting

Hyperglide Plus technology changes the rules of the game, allowing you to climb, sprint or ride without stopping to think about your next gear change. The new Di2 system uses the brand's exclusive wireless technology to ensure faster and more accurate shifting. The battery life allows you to ride 1000 km before needing to be charged.

  • The world's most inspired drivetrain

The Ultegra R8100 groupset has the fastest and most inspired drivetrain on the market and is packed with innovative features, such as Hyperglide Plus technology, which is coming to the road for the first time. The new Di2 shifting system features a wireless integrated circuit. At the same time, the change to a 12-speed cassette ensures that you have the full development range you need.The power sensor takes Shimano power data accuracy to a new, more accessible level. Ergonomics and aerodynamics have been improved in every respect.  And you can configure the drivetrain the way you like it via Shimano's user-friendly E-Tube application.

  • Optimised braking control

Quieter and smoother, the new Ultegra braking system will give you even more precise modulation and stopping control on every ride, thanks to Shimano's proven Servo Wave Action technology and improved brake lever ergonomics. Easier to maintain, the completely redesigned hydraulic disc brakes balance speed control and stopping power like never before. While the new caliper design reduces the risk of friction. With even better braking, the Ultegra will allow you to concentrate on your next sprint, the next descent or conversations with your fellow riders.
