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 R8000 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 R8000 uses the well known mechanical parts and cables, Ultegra R8070 (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.

The derailleurs are more compact and lighter than their predecessors. The rear derailleur is updated with an automatic protection system that moves the cage out of harm’s way in case of a crash. There are two versions of the rear derailleur. 
A SS for cassettes up to 28T and a GS for cassettes up to 32T. The 32T GS rear derailleur in combination with a compact front crank setup offer a full wide gearing setup. Both rear derailleurs are featured with multi shifting. With a single press and hold of the shift button the rear derailleur goes all the way up or down the cassette. 
Or, when programmed at the E-tube platform, two or three gear shifts. Also the speed of gear shifts can be adjusted. In five steps, from very slow to very fast.
