Shimano 105 Di2 RD-R7150 rear derailleur
The RD-R7150-12 rear derailleur is the heart of the current Shimano 105 groupset. With the step to the 12-speed shifting system, the gear jumps are also smaller. To carry out switching operations accordingly fast, the Shadow RD rear derailleur is equipped with a powerful motor that implements in conjunction with the optimized link structure gear changes within a fraction of a second.
As a central component in the electronic Di2 system, the Top Normal rear derailleur is not only wirelessly connected to the STI brake/shift levers, but also combines charging port, LED display, setting switch and more in a compact package. Thanks to integrated D-Fly connectivity, wireless communication with compatible smart devices is also possible. In addition, the low-profile design reduces the risk of damage from contacts and drops.
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.
D-FLY | D-FLY is an NFC network that can connect wirelessly not only with electronic Shimano components, but also with compatible bike computers and smartphones. Using Bluetooth and ANT+, it allows data transfer to Shimano E-Tube Project and E-Tube Ride apps as well as third-party software.
