Shimano 12 Speed Groupset

We take years to give you seconds. The pinnacle of Shimano road technology and innovation, the new 12-speed DURA-ACE R9200 and ULTEGRA R8100 groups are our fastest, most inspired drivetrains ever. 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 wheels.
