    Why We Like The Dura-Ace FC-R9100 11-Speed Crankset

    If you, like a few of us old souls around the Competitive offices, are holding fast to your belief in the soul of mechanical shifting, Shimano hasn't abandoned you. Though the world may very well be moving towards 100% electronic drivetrains someday in the future, mechanical still makes a hell of a case for itself. With smooth lines, elegant finishing, and functionality beyond reproach, the redesigned mechanical Dura-Ace drivetrain calmly holds its own in this brave new world of wires, batteries, and display screens. It's fitting then, that the Dura-Ace FC-R9100 11-Speed Crankset also comes with the double chainrings that many roadies are loathe to abandon just yet. Call upon your granny gear when needed with this lighter, stronger version of a top-end classic, and embrace tried-and-true tradition of cables. Of course, in the even that you do decide to run electro-shifting, the crank's ring profile plays just as nicely with Di2 derailleurs.

    • A top-of-the-line classic continues to keep up with the times
    • Redesigned crank arm accommodates disc brake frames
    • Chainline and tooth profile adapted to gearing on disc race bikes
    • Reduction in weight without a sacrifice in strength
    • Allows for huge range of gearing options with a single crank
    • Shimano proves there's still a place for aluminum crank arms at cycling's most elite levels


    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: True to size

    First DuraAce crank set. How could it get out of the factory with a bent inner chainring. Of course Competitive sent out a chainring when I called. The packaging was in no way damaged. ? Dunno.
    Super happy to have a Dura Ace build up.
    However bike fitter thinks I should get a replacement saddle because the front of the ISM saddle are not in the same plane.
    Further more the LBS that built up my bike thinks the Dura Ace derailleur isn’t right. I’m going to adjust the derailleur and see if the shifts get better. It’s not at what you would expect from Dura Ace $$$$.
    Do 9100 DA rear derailleur have bent carbon cages?

    Made the switch

      Black,170mm 52/36 628g per CC, mine weigh 632.=458 +174

      my favorite cranks

      • Familiarity: I've put it through the wringer

      I have been using DA cranks for quite a while now, I've had some others here and there but I always go back. They are as stiff and efficient as they come. I really can feel a difference and I'll keep putting them on my personal bikes. Hit me up with any questions on them.

      Doesn’t disappoint

      • Familiarity: I've used it several times

      I put on the crankset a few weeks ago. I’ve put on 350 Miles since then.

      Stiff and light. Does exactly what it should do and I’m as satisfied with it as I am with the other dura ace components.

      ugly duckling that grows on you

        When R9100 was first announced, I thought it was by far the ugliest group set on the market. Most people still think this, but the wide arm design has grown on me. In line with the rest of the group, its not really much of a revolution as just a small evolution. As always, the chainrings on the crank really are the shining star. Cold forged and filled with injection molded carbon fibers, they are both ridiculously stiff yet super light. They did change the spacing of the rings slightly, but they are realistically compatible with any 11 speed groupset.

        Stiffer Without Sacrifices

        • Familiarity: I've used it several times

        Using these on my new Time and happy with the results so far. Stiffer and more adaptable to new frame designs (disc and shorter chainstays) and delivers power transfer and crisp shifting.

        Why 4 stars?
