Product DescriptionShimano Ultegra 6870 11spd Di2 Road Group: 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.
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.
