    Details

    A confession: We’ve always loved Shimano’s front derailleurs. They’ve always worked flawlessly and quietly. And then we rode Di2 bikes. The precision of the Di2 front derailleurs cannot be overstated. They work so phenomenally well, so precisely, and so quietly that we often forget they’re there. They auto-trim, eliminating chain rub, and they adjust themselves when they’re out of alignment. It’s among our favorite components, and the Ultegra 6870 is a fortunate beneficiary of this technology and design.

    Di2 all the way

    • Familiarity: I've used it several times

    It's hard to talk about one piece of an electronic drivetrain independent of the rest, but I shall endeavor to do so.

    Ultegra is sweet spot for price and performance and the Di2 version is really no exception. The looks are polished if somewhat utilitarian - none of that Campy flair here. But the real concern here is shift quality and that's where this derailleur really shines.

    Simply put, this system does not mis-shift. Ever. Even those tough jumps up to the big ring are handled quickly and efficiently. The responsiveness is confidence inspiring to say the least.

    When Ultegra can be this good why bother with Dura-Ace?

    Remarkable

    • Familiarity: I've put it through the wringer

    In the word of front derailleurs, the Ultegra Di2 front derailleur is pretty remarkable -- precise, fast shifting every time. I've used it on gravel bikes, road bikes and aero bikes, in each application it has impressed.

    Remarkable

    Reliable

    • Familiarity: I've put it through the wringer

    I purchased a bike with Ultegra Di2 about a year ago. It was my first foray into electronic shifting and it's just flat out reliable. The batteries last forever and you get quality dependable shifting. In the year that I've had it, I have had zero hickups.

    Sticking with it!

    • Familiarity: I've put it through the wringer

    Building a new bike is always exciting and it's always tempting to try new things. The drivetrain decision was particularly easy this time however, after my previous experience with Ultegra Di2. The light weight and sexy lines of the Dura Ace Di2 group are indeed tempting, but for the cost you can't go wrong with the Ultegra. I have had exactly :::zero::: issues with my previous group other than problems I have inflicted (read: derailleurs are not-crash-proof). This also makes the Ultegra a great option if you race, where close quarters and periodic pavement sampling are a fact of life.

    Outstanding Technology and Operation

    • Familiarity: I've put it through the wringer

    This front derailleur is part of a complete Ultegra Di2 system. It works excellent. Shifts from the small chain ring to the large one are so smooth it's like an automatic transmission in a car. Shifting down to the small chain ring is very smooth also. Follow the Shimano Dealers Manual (available on line at Shimano.com) for install and set up. With a mid level of bicycle maint. experience it can be set up to operate smoothly and reliably.

    I ordered the 6870 front derailleur knowing it was backordered, is there a time frame when it will be shipping out?
