The new generation of Shimano’s famed Ultegra groupset has arrived. Introducing the Ultegra R8150 Di2 Groupset. This 12-speed system utilizes Shimano’s ultra-quick, ultra-precise Di2 shifting system and their newest Hyperglide+ drivetrain technology for accurate shifts at the press of a button. This mostly wireless system allows for a fully wireless cockpit for a cleaner look and for easy use with an integrated handlebar and stem. This completely-updated Ultegra Di2 R8150 system shifts faster and with more precision than previous generations, and features refinements to everything from hood ergonomics and button location, to brake bite point and performance. This special groupset includes nearly everything you need to get a new bike build rolling, or to upgrade an existing bike, including shifters, derailleurs, crankset, cassette, and more.
