Shimano Dura Ace R9250 12 Speed Di2 Rim Brake Groupset Kit

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 Di2 FD-R9250 12 Speed Front Derailleur - Braze On

The Science of Speed. 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.

The electronic Di2 parts rely 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.

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

The Science of Speed. 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.

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.

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.
