Shimano 105 R7170 Di2 12 Speed Hydraulic Shifter

Shimano ST-R7170 105 Double Hydraulic Di2 Lever

Bringing electronic wireless Di2 shifting to a new set of riders, this shift/braker lever combines industry-leading functionality with trickle-down technologies from the Dura-Ace and Ultegra series. After years of research and development, Shimano’s 105 series now offers Di2 electronic shifting for the first time, bringing precise, intuitive gear changes to even more riders. Not only does it offer worry-free Di2 shifting in a compact shifter size, but it also features technologies such as Reach Adjust and customised button functions that allow you to dial in your ideal ergonomics. For those who have only experienced mechanical shifting and ergonomics, this model marks a new era of affordable performance.

Reach Adjust

This model’s brake lever is equipped with a Reach Adjust mechanism. The distance from the handlebar grip to lever can be adjusted to suit any hand size, type of riding and individual rider preferences.

E-Tube Project

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

Dual Control Lever

DCL stands for Dual Control Lever. It has brake and shifting functions in the system and enables easy operation. Ergonomic innovation is probably more critical to the higher standard performance than the added gearing. The shift internals borrow the robustness from Shimano’s MTB technology and are so smooth and effortless that one finger shifts front and rear are possible. Indeed, shifting is the ultimate act of Shimano Total Integration, and simply has to be experienced to be understood.
