Shimano Dura-Ace R9200 12 Speed RIM Brake Groupset
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. Here’s a quick rundown on how each of them contributes to faster, more efficient road riding.
New Di2 dual control levers feature dramatic, all-new ergonomics and act as the command center. Both DURA-ACE and Ultegra levers have a longer, slightly curved hood body for a more comfortable and secure grip. Shift buttons are easier to reach and differentiate with extended switches and an increased offset between them. With better access and faster shifting, you’ll always find yourself in the right gear.
The backbone of these two new groupsets is the game-changing HYPERGLIDE+ shifting technology. First introduced on Shimano mountain bike groups, this unique chain-and-cassette interface smoothly guides the chain up and down the cassette for fast and precise shifting in both directions — even under extreme pedalling load.
