Shimano Ultegra R8150 Di2 Rim Brake Groupset -

Shimano Ultegra DI2 R8150 12 Speed Rim Brake Groupset is highly customizable using Shimano's user-friendly E-TUBE App on your smartphone or PC. With E-TUBE, you can set up your drivetrain just the way you like it; adjust shift speed, alter the number of shifts per button actuation, and utilize synchro and semi-synchro functionality. You can also use E-TUBE to connect your Shimano 12-speed wireless drivetrain with Shimano Connected Partners like Garmin and Wahoo. This connectivity allows you to take advantage of features like scrolling through GPS screens using buttons on your shifter rather than taking your hands off the bars.

The New ULTEGRA Di2 features 11-30 and 11-34 cassettes paired with 50-34 or 52-36 chainrings to deliver a gear range to meet any situation. A single rear derailleur option has eliminated any need for long or short cage models, one derailleur will do it all.
