Shimano Ultegra Di2
Ultegra Di2 R8100 is Shimano's most inspired drivetrain, packed with innovative, game-changing features. HYPERGLIDE+ technology allows for crisp, seamless shifts both up and down the gear range, even during maximal efforts. The new Di2 shifting system introduces Shimano's exclusive wireless integrated circuit, and the move to a 12 speed cassette ensures you have all the gearing you need. Ergonomics and aerodynamics have been enhanced at every turn, and you can set up the drivetrain just the way you like it via Shimano’s user-friendly E-Tube app.
