Shimano 105 R7170 Di2 12 Speed Groupset Disc (Excluding BB)

The new SHIMANO 105 brings Di2 shifting to a new group of riders.

The new SHIMANO 105 R7170 brings Di2 shifting to a new group of riders. For those who have only experienced mechanical shifting and ergonomics, SHIMANO 105 represents a transformation of the road cycling experience.

The SHIMANO 105 R7170 features hybrid operation. The battery, located inside the frame, the derailleur, and the derailleur are all wired together. Meanwhile, the levers have a wireless operations.

The current Di2 (Digital Integrated Intelligence), as we have commented, lacks cables from the controls, there being a single cable that connects the change and derailleur and battery. This hybrid character (some components connected by cable and others wireless), offers fast and precise changes, with a long battery life and without interference.

The new groupset incorporates an advanced 12-speed transmission, thus having more gears available to improve pedaling efficiency in any situation. An improved interface and ergonomics, achieving a magnificent balance between comfort, aerodynamics and aesthetics.
