Detailed product description
The Synchro Shift technology in the shifters allows you to change gears at both the front and the back with just a single shifter. An adjustable shift-range allows you to tune when the Di2 system will automatically shift into the large ring when changing up, or into the small one when changing down. Whichever gear ratio you choose, Shimano's Rhythm Step ensures you'll get it with as little shifts as possible. This ensures you as a rider are able to continue at a more stable cadence and ride more fluently. No major jumps in gears, no overworked muscles or joints, just effortless (relatively) pedaling in your own choosen gear range. No compromises, rather just focus on simplicity and fun!
