WORLD’S MOST INSPIRED DRIVETRAIN
The ULTEGRA R8100 group is our fastest, most inspired drivetrain at this level and packed with innovative game-changing features. HYPERGLIDE+ technology comes to road cycling for the first time. The new Di2 shifting system introduces our exclusive wireless integrated circuit. Meanwhile, the move to a 12-speed cassette ensures you’ll have all the gearing range you need. New to ULTEGRA, the power meter brings Shimano power data precision to a new, more approachable level. Ergonomics and aerodynamics have been enhanced at every turn. And, of course, you can set up the drivetrain just the way you like it via Shimano’s user-friendly E-TUBE app.
