what advantages and Full reviews of Shimano Di2 Ultegra RD-6870 Rear Der :
DESCRIPTION : 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. Using Di2 components with different firmware versions may cause malfunctions. 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. Finally, customize your gearing choices for tough climbs with an all-new 32T cog capacity in the GS cage version of the derailleur. 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. Go Ultegra 6870 for precise, insanely fast shifts across an 11-speed cassette, no matter the conditions, with just one click of a button. 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. To update the firmware on your components, use the Di2 system checker from Shimano by clicking here. With the E-tube platform, the rider can customize exactly how many gear changes a press and hold actuates. The Ultegra 6870 Rear Derailleur utilizes Shimano's E-tube software for ingenious customization of shifting.
