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

Dura Ace R9200 – Never Compromise

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.

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.

Ports: 1x EW-SD300, 1x EW-EC300

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.
