Shimano Ultegra Di2 RD-6870 Rear Derailleur

In true Ultegra fashion, the 6870 series takes the pro tested Di2 technology from its steeper Dura-Ace big brother, to a price that non-pros can sink their teeth into. Di2 electronic shifting enables a whole new level of riding that can’t be experienced through traditional mechanical shifting, by offering smoother, faster, more precise and nearly flawless shifting. The Ultegra 6870 Rear Derailleur utilizes Shimano’s E-tube software for ingenious customization of shifting. For example, the 6870 Rear Derailleur has the ability to shift up or down through all of the gears with a single press and hold of the shift button via the multi-shift function. With the E-tube platform, the rider can customize exactly how many gear changes a press and hold actuates. Five shifting speeds are available, ranging from slow to lightning fast. On top of it all, there are no cables to wear out or become contaminated. Go Ultegra 6870 for precise, insanely fast shifts across an 11-speed cassette, no matter the conditions, with just one click of a button.
