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. Sharing the same ergonomics and feel as the pricier Dura-Ace line, the Ultegra 6870 uses Shimano E-tube software for digital operation, reducing the chance of human error, minimizing the chance of missed shifts, and enabling the automatic trim feature for stress-free, smooth riding. The hoods have been slimmed down and the overall weight of the levers has been reduced by 20 grams. On top of it all (pun intended), the top-side brake lever access has been improved, offering a closer pivot location for better control from multiple hand positions. The Ultegra 6870 Di2 shift levers are the quintessence of trickle-down technology done right!
Please Note: All Di2 components on the bicycle require the same firmware version. Using Di2 components with different firmware versions may cause malfunctions. To update the firmware on your components, use the Di2 system checker from Shimano by clicking here.
