About Shimano Ultegra Di2 RD-6870 11sp Rear Derailleur

The Shimano Ultegra Di2 6870 Rear Derailleur makes shifting smooth, smart and fast. It shares DNA with its Dura-Ace 9070 cousin and features a much slimmer profile than the previous Ultegra Di2 rear mech, with 11-speed shifting capability. The wiring is tidier than before and this long cage (GS) version can stretch to a 32T cog in the rear.

E-tube technology is the key to Shimano electronic shifting, with advances in the package software allowing riders to customize shifting speed and even how many gears the rear derailleur shifts through when holding the shift button down. The 6870 rear derailleur even has built in crash protection, forcing the rear mechanism to compact and tuck away in the event of a crash. Ultegra has always been an enticing balance of both performance and value but Shimano has truly outdone themselves with Ultegra 6870 11-speed Di2.
