The complete Shimano Ultegra R8100 groupset is Shimano's fastest and most inspired drivetrain at this level and boasts a host of innovative features. Hyperglide+ technology comes to road cycling for the first time. The new Di2 shifting system introduces a unique wireless integrated circuit. Meanwhile, switching to a 12-speed cassette ensures you have the full range of shifting you need. Ergonomics and aerodynamics have been improved at every turn. And obviously, you can configure the drivetrain as you prefer thanks to Shimano's easy-to-use E-TUBE app.

The new groupset brings a sleek new wireless cockpit, clean aesthetics, improved ergonomics and easier maintenance to your bike. All this is thanks to the new wireless system that Shimano has developed to make shifting even faster, without compromising precision or reliability.

Shimano's ultra-fast shifting innovation brings an intuitive and seamless experience to road cycling. Innovative Hyperglide+ technology allows you to climb, sprint or flat out without having to stop to think about your next gear change. The new Di2 shifting system uses proprietary wireless technology to deliver the fastest, most precise shifting on the market. Battery life is also best-in-class, with a centralised battery that delivers approximately 1000 kilometres on a single charge.

Braking control has been optimised. Quieter and smoother, the new Ultegra brake system means you can enjoy even more precise stopping modulation and control on every ride thanks to Shimano's proven Servo Wave Action technology, and improved brake lever ergonomics. The completely redesigned hydraulic disc brakes are easier to maintain and balance speed control with stopping power like never before. What's more, the new calliper design minimises friction. A major accomplishment in braking, Ultegra lets you focus on the next sprint, the next descent or conversations when riding with the group.
