The groupset consists of:
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.
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.
The front derailleur cable routing has 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.Shimano Synchronized Shifting
With Synchronized Shift enabled, it is possible to control both derailleurs with just one shifter. With full Synchronized Shift, the front derailleur detects the position of the rear derailleur and automatically shifts to the most efficient gear for the best chainline, so you never have to worry about front shifting or correction shifts again.
While semi-Synchronized Shift enables you to shift the front derailleur manually, allowing you optimal more control in choosing the best gear combination for your style of riding. The system automatically takes care of the necessary correction by shifting into the right rear gear for the best chainline.
Synchronized Shift is completely compatible and customizable with E-tube.
Chain stay angle: 61-66°
Front (FD-R9150) and rear derailleurs (RD-R9150) incorporate these new cockpit functions. Both electronic derailleurs are compact and designed to protect the shifting operation in the event of a crash. The low profile of the rear derailleur also comes with SHIMANO SHADOW RD technology, positioning the derailleur further below the functioning sprocket.
The mechanical Di2 ST-R9150 Dual Control levers feature a refined hood shape with svelte shared ergonomics for more rider control in race conditions, regardless of braking choice. The ergonomically-enhanced Di2 shift levers produce a more defined shift click for a more intuitive feel and quicker shifting operation and expanded E-Tube customization allows every switch the option to independently turn on or off multi-shift. Thanks to the customizable function the levers fit any riding style and the carbon composite plastic hood material drops the weight of the whole construction.
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.
Compatible with 28C tires.
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.
Shimanos premium 11-speed chain delivers better performance for mountain bikers. The CN-HG900-11 uses a HG-X11 special asymmetric plate design and Shimano’s new SIL-TEC surface treatment.
The EW-WU111 is the successor version of the EW-WU101, in a new Design.
The Di2 wireless unit is a compact wireless data transmitter. It easily plugs into the E-tube wiring system and seamlessly connects Di2 equipped bikes to a compatible wireless cycle computer. Shimano D-Fly transmits data through a proprietary private ANT wireless protocol and allows riders to monitor Di2 gear position, battery life, as well as some other common rider data functions. The Di2 Wireless Unit is powered by the same Di2 battery that powers the Di2 shifting system. It is compatible with ANT+ devices like the Shimano Action Camera CM-1000 or the PRO SCIO ANT+ cycling computer.
One feature on the EW-WU111 is a wireless Bluetooth connection to Shimano’s E-TUBE program, which is the system Shimano uses to set up and control the Di2 shifting behaviour. Through Bluetooth technology riders or mechanics can wirelessly communicate with the EW-WU111 wireless data transmitter unit via a computer, tablet or a smart phone. As well as allowing wireless workshop customizability, it allows riders to customize their shifting preferences on the trail via an app on their smartphones.

The EW-RS910 can be installed in the bar-end or in the frame. It offers an interface for charging the battery and a charging indicator. With the button of the EW-RS910 and the X and Y switches of the STI, the front and rear derailleur can be adjusted.
