Description With technology trickling down from flagship Dura-Ace, Shimano's Ultegra R8150 Di2 Groupset is better than it has ever been before. It perfectly balances performance with value, and the components are slick, reliable, and only create a minimal weight penalty compared to Dura-Ace.

Shifting is flawless, and faster than previous iterations, while operating almost silently. This is thanks to Hyperglide+ tooth profiles, meaning that the chainrings and cassette have an improved connection with the chain, essentially improving shifting under load, across the cassette. Adding in a 12th sprocket, progression through the gears is smoother too.

There are plenty of configurations to choose from, including various crank lengths and both mid-compact and compact chainrings, making this groupset a fantastic option for the majority of riders looking to upgrade their bike to an electronic system.

You can also pair the system with most third-party cycling computers, including Garmin and Wahoo, which allow you to monitor gear selection or battery status.
