Are you chasing the best mechanical group set that money can buy? Very fast shifting with a lightweight and accurate design allows you to hit the right gear every time. No need to worry about consistently tuning the system as you would with some of the other options on the market, this is designed to last the long haul. Even better, this has been designed with ease of use in mind, with even less effort required to perform each individual shift using the mechanical advantage to improve shifting performance.
System engineering at its peak. Each of the components magnifies the qualities of the others for an unparalleled level of performance. Optimizing input to maximize output. That's how it achieves supremacy.
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.
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.
The drivetrain is perfectly balanced for improved performance. All components are part of an integrated system for optimum power transfer, including the vast array of gearing choices to perfectly match your riding style and needs. Repeatedly tested for maximum efficiency on all terrains, under all conditions.
The R9100 series crankset achieves the ultimate in optimal power transfer. It does this through its broader Hollowtech II arm and a more reinforced outer chainring on its unique asymmetrical four-arm spider construction. The new R9100 cranks set the highest standards for stiffness and lightness.
Gears to match your riding style as well as your chosen terrain with Shimano’s new rider-tuned cassette sprockets. The new lightweight titanium 11-speed cassettes are available in various sprocket combinations, including the new 11-30T version. Fast, accurate and smooth shifting is guaranteed in all situations.
The R9100 mechanical Dual Control Lever offers a shorter lever stroke, an expanded reach adjustment range for precise lever position, and lighter front shifting operation for quick and intuitive shifting (and braking) in all situations. Further improvements are its renewed hood cover material and its comfortable ergonomic shape with more grip.
The 11-speed DURA-ACE rear derailleur has been redesigned for lighter, quicker operation with the help of low-friction polymer-coated cables. This new derailleur is also Direct Mount-equipped offering a stiffer foundation for improved shifting as well as minimising the chance of frame damage through a crash. Front derailleur cable routing has also been adjusted to further reduce shift force. The precise and easy front derailleur set up offers more cable routing options and integrated cable tension adjustment.
The sleekly designed R9100 series rim brake, with its lightweight Dual-Pivot Brake Caliper, offers maximum precision for better control and more confidence in the races. Simple to set up and easy to maintain through easy tool access and fast wheel replacement.
