Shimano 105 Di2 12-speed Disc ST-R7170R rear road bike right-hand lever

To celebrate the 40th anniversary of its 105 groupset, Shimano has decided to bring its third groupset into Di2 mode, like the Dura-Ace and Ultegra. Developed with input from top professional cyclists, the ST-R7170R rear shifter offers the same performance in terms of compactness and ergonomics as the Dura-Ace shifter. It thus promises precise and rapid gear changes.

The Dual-Control lever is as ergonomic as possible. The palm rest on this rear lever is raised to provide extra comfort. With this Shimano 105 Di2 12-speed ST-R7170R lever, you’ll maintain control in all conditions. All the more so as the braking area has been widened to ensure you’re as comfortable as possible on the road, whether climbing, descending or on the flat.
