Shimano Ultegra Di2 R8170 2x12S Groupset | 50/34T | 11-34T | PF86.5 (With Electrical Part) Shimano

Increasing speed involves a great responsibility. That's why Shimano took a 100% performance-focused overall approach in their aim to make the new Ultegra 12-speed groupset even faster. Whether racing regional races, trying to beat your personal best, or riding for pure fun with the buddies, this new groupset delivers unparalleled control and comfort, all day, every day. It's the science of speed. And that's what sets Shimano apart.

The Shimano Ultegra R8100 group has the fastest and most inspired drivetrain at this level, and is packed with innovative features that redistribute the cards. HyperGlide+ technology hits the road for the first time. The new Di2 shifting system features Shimano's exclusive wireless integrated circuit. And at the same time, switching to a 12-speed cassette ensures you'll have the full gear range you need.

New to the Ultegra groupset, the power meter takes Shimano power data accuracy to a new, more accessible level. Ergonomics and aerodynamics have been improved at all levels. And, of course, you can configure the drivetrain just the way you like it via Shimano's user-friendly E-Tube app.

Quieter and smoother, the new Shimano Ultegra braking system lets you enjoy even more precise modulation and stopping control on every ride, thanks to Shimano's proven Servo Wave Action technology, and improved ergonomics of the brake lever. Easier to maintain, completely redesigned hydraulic disc brakes balance speed control and stopping power like never before, while redesigned brake calipers limit the risk of friction. By further improving its braking, the Ultegra group allows you to concentrate on the next sprint, the next descent or the conversations with your companion on the road.
