The new DURA-ACE R9100 adopts Synchronized Shifting, a system that Shimano first developed for mountain bikes. This allows riders to operate both derailleurs just by pressing a single shift button.
Favoured by the majority of teams in the pro peloton, the Dura-Ace 11-speed groupset emulates its predecessor. Every component in this Dura-Ace groupset has been re-engineered for optimal weight savings alongside maximum energy output with minimal loss through friction or non-compliant components. The result is a beautiful marriage of stiffness with weight-savings.
Dura Ace R9100 Groupset 2×11-speed – Mechanical Rim Brakes
The groupset consists of:
- Shimano Dura Ace FC-R9100 Crankset 2×11
- Shimano Dura Ace FD-R9100 Front Derailleur 2×11
- Shimano Dura Ace CS-R9100 Cassette 11-fach
- Shimano Dura Ace ST-R9100 STI 2×11 – Paar

- Shimano Dura Ace BR-R9100 Brakes – FW + RW
The DURA-ACE groupset is the result of Shimano’s ongoing passion for technology. This is reflected in every single component in the groupset. All components are joined together to work as one, reinforcing each other for unparalleled performance. This is how DURA-ACE achieves ultimate supremacy.

RD-R9100 Rear Derailleur
The 11-speed DURA-ACE rear derailleur has been redesigned for lighter, quicker operation with the help of low-friction polymer-coated cables. This derailleur is also Direct Mount-equipped offering a stiffer foundation for improved shifting as well as minimizing the chance of frame damage through a crash.
