Dura-Ace R9100 groupset
ULTIMATE CREATION IN SYSTEM ENGINEERING
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.
EVOLVED THROUGH SCIENCE
Decades of experience as the undisputed leader in cycling technology has culminated in our most beautiful, progressive design ever. Sleek, powerful, effective… and evolved through science. For the new DURA-ACE groupset, we improved upon each and every individual component. Together they form a truly superior groupset. A perfectly balanced total system. Improving performance by maximising efficiency: that’s how we’re able to ensure the best for cyclists with the highest demands.
Increases efficiency and versatility
The FC-R9100 HOLLOWTECH II crankset’s shaping improves upon DURA-ACE’s iconic 4-arm design, adding strength and rigidity while minimizing weight. Shimano’s Rider Tuned gearing offers a number of chainring configurations with a singular BCD for ease of use and versatility. Through redesigned chainring tooth profiling, the DURA-ACE R9100 crankset is adapted for the latest disc brake frame designs without the need to increase q-factor.
