Shimano 105 R7170 Di2 12-Speed Groupset

The Shimano 105 R7170 Di2 Disc groupset makes professional 12-speed technology accessible to every cyclist. The innovative semi-wireless system ensures a clean cockpit without shift cables and guarantees lightning-fast shifting, comparable to the more expensive Ultegra series. Cable wear is a thing of the past, significantly increasing reliability and ease of maintenance.

The updated hydraulic disc brakes now offer 10% more clearance between the brake pad and rotor, making rubbing virtually impossible. Thanks to Servo Wave technology, the brakes engage faster and more powerfully, yet remain exceptionally controllable. This provides ultimate control and confidence on steep descents, regardless of weather conditions.

This versatile groupset is suitable for cassettes up to 36 teeth as standard, which is ideal for challenging climbs in the mountains. Via the Shimano E-TUBE app, you can easily adjust button functions and shifting speed to your preference. The R7170 is the perfect upgrade for riders seeking modern performance and electronic precision.
