The GOAT of road bike Groupsets.  The pinnacle of Shimano road technology and innovation, the new 12-speed R9200 DURA-ACE Rim Groupset is our fastest, most inspired drivetrains ever. DURA-ACE is Shimano’s best road bike groupset. It is about perfection. 

Shimano Internal 2-Port Junction for EW-SD300 12 Speed

Introduced with the Shimano EP800 series, the SD300 E-Tube components form the interface between compatible STePS parts and expand the functional range of future Di2 systems.

Shimano Dura-Ace FC-R9200 12 Speed Crankset

The Shimano Dura Ace FC-R9200 crank performs two crucial tasks: It converts pedal power into propulsion and ensures extremely fast and precise shifting.

Not only do the lightweight crank arms, manufactured using Hollowtech II technology, contribute to this, but also the uniquely designed chainrings which feature a Hollowglide construction and ensure fast as well as smooth shifting. The result is responsive acceleration from any speed securing the 2x12-speed crankset an absolute top position.

Various crank arm lengths and chainrings with 50-34 to 54-40 teeth offer variability and an optimum gear ratio for every riding situation.

Shimano Dura-Ace CN-M9100 12 Speed Chain - 116 Links Quick Link

Designed for Shimano's revolutionary XTR M9100 12-speed MTB groupset, the M9100 chain provides enhanced chain retention thanks to an extended portion of the inner plate.

The new chain features quick-link assembly and Sil-Tec treatment for extended offroad durability.

Shimano BT-DN300 Internal Battery - 12 Speed

Thanks to its compact dimensions, the flat Shimano BT-DN300 battery can be integrated inconspicuously into the seatpost or frame. Not only in terms of dimensions, it is similar to its predecessor BT-DN110, but also concerning waterproofness, it is in no way inferior.

The lithium-ion battery features three SD300 ports for the connection to front and rear derailleur. The third connector is used in the case of a fully cabled Di2 groupset.

In-house tests with the components of the current Dura Ace R9200/R9250 and Ultegra R8100/R8150 12-speed series have shown that the battery provides a powerful and stable power supply for the powerful actuators of the rear and front derailleur over a range of 1000 km on average.

Shimano Dura-Ace BR-R9200 Brake Caliper

With its sophisticated Dual Pivot construction, a symmetrical short arm design and SLR-EV technology, the Shimano Dura Ace BR-R9200 side-pull brake ensures maximum braking performance in all conditions.

Add the lightweight magnesium brake pad carriers and you have a total package that impresses with a balanced ratio between braking power, stiffness and low weight.

Shimano Dura-Ace CS-R9200 12 Speed Cassette

Speed was the mainspring in the development of this 12-speed road bike series of a new generation.

Several years of research produced those innovations that make the Shimano Dura Ace R9200 even faster. Every component has been revised, refined and optimised to enable the decisive seconds of advantage – whether as a breakaway from the peloton or in the finish sprint on the Champs-Élysées.

In the electronic Di2 version, the Dura Ace relies on Wireless technology where it matters to make shifting even faster and more reliable. Smooth shifting is also the aim of the Hyperglide+ system, already known from the MTB segment, which is designed to bring out maximum performance and the full potential of every racer.

Smooth shifting is also the aim of the Hyperglide+ system, already known from the MTB segment, which is designed to bring out maximum performance and the full potential of every racer.

The Shimano Dura Ace Di2 FD-R9250 front derailleur makes fast shifting systems even faster. Thanks to its revised design, its weight is not only less than 100 grams, the Down Swing front derailleur also performs shifting operations 4 5% faster than the predecessor model FD-R9150. In order to also cut a good figure in terms of aerodynamics, the frontal area has also been reduced by 33 %.

Shimano Dura-Ace Di2 RD-R9250 12 Speed Rear Derailleur

Faster than ever before. The RD-R9250 model not only offers the fastest gear changes on the cassette to date and the largest gear ratio range of a Dura Ace rear derailleur, but can do much more. By integrating the Wireless system and charging port into one compact unit and thus covering a wide range of functions, it practically becomes the heart and brain of the entire Di2 assembly.

The built-in transmitter ensures wireless communication with the STI brake/shift levers ensuring podium-worthy, lightning-fast and precise shifting. Using Bluetooth and ANT+, it is also responsible for data transmission to the E-Tube Project and E-Tube Ride apps as well as to third-party devices.

Besides the charging port, the Top Normal rear derailleur features a button for certain Di2 settings and an LED for status display informing you about battery level, pairing and setting mode, for example.

Shimano Dura-Ace Di2 ST-R9250 12 Speed Shifter Set

Compared to the disc brake version, the Dura Ace Di2 ST-R9250 dual control levers rely entirely on a secure cable connection and the low weight of a rim brake system. In terms of ergonomics and the use of state-of-the-art materials, the STI levers are in no way inferior to their disc brake counterparts and clearly show their racing genes.

The clearly defined click-feel of the shifting aids not only ensures intuitive, but also fast gear changes. The optimised shaping and surface structure of the horns and brake levers guarantee outstanding grip and excellent braking power transmission. Of course, for individual adjustment, the levers feature the option of reach adjustment. This means that the brake/shift levers, which are designed for reliable performance, ensure maximum control and complete confidence even under racing conditions.

For numerous customisation and configuration options, compatibility with the improved E-Tube Project app, which, like previous versions, allows you to adjust shift modes (Synchro-/Semi-Synchro-Shift, Multi-Shift), shift speed and button assignment on the fly. For connection to the BT-DN300 battery and use of additional shifters in the drops or the top of the handlebar (each sold separately), the Shimano ST-R9250 dual control levers feature 2 cable connections.

Shimano EW-EC300 Charging Cable - 12 Speed

The Shimano EW-EC300 charging cable has been specially designed for Shimano Di2 12-speed road bike groupsets and is compatible with the components of the current Dura Ace R9200/R9250 and Ultegra R8100/R8150 series.

The charging process of the electronic Di2 system is carried out starting from the rear derailleur which features a corresponding connection. However, the charging cable can also be used for compatible Powermeter cranks. In each case, it draws power via a USB-A port.

Features

Shimano Internal 2-Port Junction for EW-SD300 12 Speed

The Shimano 2 Port Junction EW-JC302 Junction allows you to connect two EW-SD300 electric wires to each other.
The wires are fixed by a plug connection.

Shimano Dura-Ace FC-R9200 12 Speed Crankset

Hollowtech II - The guiding principle of Shimano's Hollowtech II technology is the perfect balance between stiffness, stability, weight and rotational efficiency. The goal was to produce a crank that minimises the effort required for the drive and enables more efficient power transmission.

An exclusive forging process allows the production of extremely light crank arms that nevertheless guarantee maximum stiffness. The fixed connection of the right arm to the axle of the bottom bracket and its external bearing also serve an optimum relationship between stiffness and low weight.

Sil-Tec - Shimano's ultra-low friction surface treatment, Superior to simple coating, Sil-Tec is an advanced plating process that improves system performance through the use of imbedded fluorine particles. Sil-Tec products run smoother and wear longer in all conditions.
Quick-Link - Tool-free assembly for current 11-speed chains provides great convenience to user. (TL-CN10 is also available for more convenient assembly.)
HyperGlide - HyperGlide+ drivetrain’s redesigned cassette and chain promotes the next generation of MTB riding by enhancing speed, shifting efficiency and smoothness over any terrain.
HG Chain Design for HyperGlide+ - dedicated chain delivers greater chain retention, improved shifting efficiency, and smoother transmission over rough terrain.

Shimano Dura-Ace BR-R9200 Brake Caliper

SLR-EV - The SLR-EV technology extends the Shimano Linear Response concept which aims for improved response and optimal dosing.

Symmetrical Dual Pivot side-pull brakes with SLR-EV system use two bearings and a roller to achieve greater efficiency in the joint area. However, SLR-EV also has a positive effect on the modulation of Direct Mount calipers, so that current models can boast a 36 % increase in braking force.

Shimano Dura-Ace CS-R9200 12 Speed Cassette

Hyperglide+ - The conventional Hyperglide technology ensures smooth shifting upwards thanks to small shifting ramps, which guide the chain towards the next larger sprocket. Also Hyperglide+ uses this functionality but applies it in the opposite direction, too, preventing the chain from falling down when shifting downwards. The result is a smooth and consistent shifting in both directions, free of vibrations and without disrupting the cadence.

Hyperglide+ technology has already set standards in the off-road sector where it has been able to convince with its smooth shifting processes in both directions across the entire gear range.

With the Shimano Dura Ace CS-R9200 cassette, this concept now also finds its way onto road bikes to ensure worry-free upshifting and downshifting, whether it is the highest power input on climbs or the sprint to the finish line.

While larger teeth ensure maximum efficiency, the change to 12 gears is made without an increase in weight. And the 12-speed cassette is even compatible with Shimano's previous 11-speed freewheel bodies. This makes the CS-R9200 the cassette of choice on road bikes.

HyperGlide+ - dedicated chain delivers greater chain retention, improved shifting efficiency, and smoother transmission over rough terrain.

Shimano Dura-Ace Di2 RD-R9250 12 Speed Rear Derailleur

Shadow RD - With their sophisticated technology, Shimano Shadow RD rear derailleurs are especially intended for more aggressive riding style. Their super low profile design carries many benefits. Thanks to the low profile and a single tension construction, the derailleur does not hit the chain stay in rough riding conditions. The result is smooth and silent performance.
