Shimano Ultegra R8100 Di2 Groupset Description:

Crisp shifts and unparalleled performance. Ultegra Di2 boasts the same level of shifting and braking as Dura-Ace with only a slight weight penalty. Sometimes referred to as “the working man’s groupset,” Ultegra provides incredible value without giving up its high level of functionality. Some highlights of Ultegra include the responsive shifts of the ultra-fast rear derailleur and the smooth modulation of Servo Wave brakes. No matter where your road cycling journey takes you, Ultegra Di2 shifting is up for the task.
