Product technical specification

TECHNOLOGY

Di2 - The advantages of Di2 (Digital Integrated Intelligence) are clear for everybody who has tested it: changing gears becomes easier, effortless and faster by simply touching the shift buttons. Control at the top of your fingers. Additional benefits include an automatic trimming front derailleur, unmatched precision plus super easy installation and adjustment. This allows automatic chain guide movement in response to the gear position of the rear derailleur. There is no more need for concentration on trimming when riding.

The mechanism rear derailleur, SHIMANO SHADOW RD, is intended for more aggressive riding. Its super low profile design carries many benefits. Because of its low profile and single tension construction, the derailleur does not hit the chain stay in rough riding conditions. The result is smooth and silent performance.

Important: All Shimano Di2 electronic components require the same firmware version. In order to diagnose, read, or update firmware, an optional device is needed. Operating components with different firmware versions may cause malfunction or loss of function.
