The pinnacle of Shimano road technology and innovation, the new 12-speed ULTEGRA R8100 group is a fast and acute drivetrain. The Science of Speed, Shimano’s design philosophy for its latest road groups, is comprised of five elements: a new Di2 platform, a refined interface, the addition of Hyperglide+, a category redefining brake system, and a collection of new carbon wheels that are tubeless disc and Shimano 11 and 12 speed compatible.
