Shimano 105 R7150 Di2 Rear Derailleur

Shimano 105 R7150 12-speed Rear Derailleur

The Shimano 105 R7150 12-speed rear derailleur delivers lightning-fast and precise shifting performance, even when you’re putting power on the pedals—such as during a climb or a sprint. Thanks to its semi-wireless design, there’s only a single cable connection between the battery and the derailleurs, making the system clean and easy to install.

A major advantage is that you only need to adjust the derailleur once. After that, it will function reliably for the entire lifespan of your road bike without the need for repeated fine-tuning. However, keep in mind that the long cage of this model is slightly more vulnerable in the event of crashes or impacts.

With a maximum capacity of 41T and compatibility with cassettes up to 36T, this derailleur is ready for versatile use in the mountains as well as on flat roads.

In short: a reliable, fast, and modern derailleur that elevates the performance of your Shimano 105 Di2 groupset to the next level.
