The digitally controlled 11-speed Dura Ace 9070 Di2 group set. The continuation of a new dimension of shifting. Precise and very fast shifting under all conditions and situations.
The Di2-technology (Digital Integrated Intelligence) reduces human errors in shifting. It features "Fly by Wire" for easiest shifting performance. It defines new standards for the high-performance sports.
There is no need for rethinking. The shifting operation is similar to the mechanical Shimano shifting system - just press the button without any effort. The program controlled front- and rear derailleurs shift the gears very fast and precise. The danger of chain drop is minimized. The rear derailleur is electronically adjustable, even when riding. The front derailleur adjusts automatically to the chain line in relation to the rear derailleur gear position. No concentration is wasted for trimming when riding, so the rider can spend full attention to the race.
New technologies in manufacturing and a generous use of titanium and carbon reduce the components weight without losing performance, stiffness or durability. A hollow forged chainring saves weight and increases durability by 20% for better power transfer.
