Shifting Your Expectations
The DURA-ACE series is SHIMANO's lightest, most ergonomic, and most precise groupset ever. As well as delivering the finest mechanical performance, it also serves as the core chasis for the revolutionary Di2 digital shifting system. The extra eleventh gear and numerous other enhancements combine to deliver a truly dominating performance. When you ride DURA-ACE, you're riding to win.
Making the best just a little better (if you like the idea of electronic gear shifts), Dura-Ace Di2 is the flagship Shimano groupset and demonstrates the current zenith of groupset technology. It’s light, it works well, and it’s used by pro riders in the world’s biggest races.
