Product Information

Part of Shimano's game-changing 7100 series, this 12 speed rear derailleur delivers faster, more accurate rear shifting with wireless Di2 connectivity. Benefitting from a more compact design that integrates the wireless unit, charging port and function button, you can easily check the battery level and Bluetooth/ANT pairing success with your cycle computer/smartphone/tablet. Offering a more personalised touch, this model also enables you to select your preferred shift mode and view adjustment mode information if you wish to tweak or tune your rear derailleur.

Rear Derailleur with Wireless Di2 Shifting
Receiving the wireless shifting signal from the shift lever, the Shimano 105 rear derailleur completes a shift in the blink of an eye with its high-performance motor and optimised link structure. This is the hub of the Di2 system, with the charging port, indicator LEDs, adjustment switches and more integrated into a compact package. A low-profile design reduces damage from contact and falls.

Direct Mount Rear Derailleur
Rear wheels are easier to remove with a mounting option for Shimano Shadow RD and Shimano Shadow RD+. The direct mount feature is designed to suit a wide range of contemporary frames with large-section chainstays.

E-Tube Project
Shimano’s E-Tube Project Cyclist application allows you to customise your bike, update firmware, and maintain it by connecting it wirelessly to your bike. You can also get more detailed bike maintenance by connecting to your bike by wire with the E-Tube Project Professional application.

E-Tube Ride
Shimano’s E-Tube Ride application allows you to visualize your ride with a route map to your destination, a real time ride data display, and ride record data on your smartphone while you are on your bike. You can also upload your ride log data to Strava.

Shimano Shadow RD
This rear derailleur features Shimano Shadow RD mechanism that is intended for more aggressive riding. Its super low-profile design carries many benefits. Because of its low profile and single tension construction, the derailleur does not hit the chain stay in rough riding conditions. The result is smooth and silent performance.
