Shimano 6870 Ultegra Di2 groupset lets you experience the power, speed and efficiency of electronic shifting. It's race proven and incorporates all the new technology from it's bigger brother (Dura Ace) into a more affordable package.
In 2008 SHIMANO first introduced electronic shifting to road cycling in its Dura-Ace 7970 groupset.
In 2011 it became available for Ultegra.
Today SHIMANO announced they will integrate its electronic shifting technology (Di2) in their recently introduced Ultegra 6800 groupset.
Ultegra takes pro-tested technologies to a wider audience.
Whether it is a mechanical or electronic shifting interface, Ultegra provides the highest quality outside professional racing.
The DNA for both the mechanical and electronic version of the group is the same. They share the same 4-arm cranks, 11-speed cassettes, dual pivot brakes, Sil-tec chain and 11-speed wheels. What makes them different is the shifting interface (shift lever and derailleurs). Where Ultegra 6800 uses the well known mechanical parts and cables, Ultegra 6870 (Di2) uses an electronic shifting system.
Compared to the previous Ultegra Di2 (6770) SHIMANO improved the ergonomics of the dual control lever for easier access. Especially on top of the – slimmer – hoods riders have more control than ever. Also the shape of the shift button improved and the contrast of the surface is more recognizable.
