Shimano 105 ST-R7120 STI Shifter

With the mechanical 12-speed components of the 105 series, Shimano offers a shifting system for the most diverse types of road cyclists. However, the ST-R7120 shift/brake levers are not only characterized by the fast and intuitive shifting quality typical of the series, but also know how to convince on an ergonomic level thanks to improved grip and optimized comfort features.

A wide-ranging evaluation of different hand shapes and sizes has resulted in a modified grip positioning and a revised brake lever and clamp design. These adjustments have reduced the distance between the grip body and the brake lever, which in turn improves the leverage and provides more control with less effort. In addition, the brake/shift lever for 2x12-speed drivetrain systems is adjustable in reach.

Dual Control Lever (DCL) | The Shimano DCL levers combine braking and shifting functions in one control unit for easy as well as comfortable operation. In raising the standard of performance, their innovative ergonomics are even more important to consider than adding additional gearing. However, the highlight of the STI shifters (Shimano Total Integration) shifters, is the ability to change gears front and rear with just one finger. The Dual Control levers owe this not only to an extremely precise and smooth operation, but also to the same stability for which Shimano's MTB technologies are already known.
