    When innovation trickles down.

    The Ultegra Di2 ST-6870 11-Speed Shifters look to the innovations pioneered by Shimano’s top-of-the-line Dura-Ace to provide enhanced shifting performance. The new Di2 ST-6870 hoods features a slimmer, Dura-Ace-like profile that offers easy lever accessibility, and the redesigned lever blades and paddles offers more positive interaction from the hoods or drops. Shimano has also widened and re-textured the shift buttons, and the 10mm of reach adjustment for the levers makes shifting effortless when you’re buried in the drops on a long descent or during a sprint finish.

    Like Dura-Ace, the Ultegra Di2 ST-6870s now enjoy the same fully programmable shifting technology. E-Tube technology allows you to select five different shifting speeds giving you a customizable ride quality that is specific to your riding style. And with the single-wire E-Tube connection, Shimano makes this a tidy application.

    • Sleek, redesigned lever blades and paddles
    • Wider shift buttons

    Jumping on the Di2 Train

    • Familiarity: I've used it several times

    In the world of shift levers, Shimano is doing some of the finest work around. The Di2 version of their venerable Ultegra groupset is no exception and retains their near bulletproof reliability and top-notch ergonomics.

    The hood and lever design just straight up feels great in the hands in a variety of positions. Levers are easy to reach from the drops and the hoods are a solid touch point when you need to get out of the saddle.

    Shifts are precise and fast when you engage the controls. The buttons are maybe a touch hard to feel if you have thick gloves on, but this is nitpicking at most.

    Comfort & Precision!

    • Familiarity: I've put it through the wringer

    The Ultegra Di2 shifters have been fantatstic. The hoods are comfortable, and the shifts are precise every time. It's also worth mentioning that you can dial in the speed of your shifts (faster or slower from stock setting) to your liking with the help of your shop.

    Comfort & Precision!


    • 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.

    Unanswered Question

    Is the shape of the hoods any different than the previous version? I currently have the ST-6770, and I'm wondering if the 6870 will be more comfortable on my hands.

    Do the 6870 shifters come with Di2 and...

    Do the 6870 shifters come with Di2 and brake cables?
