    Easy does it.

    Smoother, more responsive levers do little if the components they work with don't improve alongside them, so we weren't surprised to see Shimano revisiting its dual-pivot rim brake design while quietly overhauling Dura-Ace for this year. The resulting Dura-Ace BR-9100 Brake Calipers make their entrance boasting a new steel bridge between each caliper arm pivot, which reduces flex for more consistent braking power when you're slamming on the levers. The bridge contributes to the calipers' enhanced modulation and more fluid, linear behavior across the braking curve, working in tandem with the levers to provide responsive stopping power whether you need to lightly temper your speed or pull up quickly to miss a crash. On the aesthetics side, Shimano subtly reduced the gap between each arm to create sleeker lines that align with the rest of the groupset's classy styling.

    • Dump speed with smooth, responsive braking power
    • Steel stabilizer reduces chatter and flex during hard stops
    • Predictable, consistent behavior across braking curve
    • Closer arms create a more streamlined aesthetic

    Dura Ace 9100 Brakes

    • Familiarity: I've put it through the wringer

    I agree with other posters about the rear brake squealing. I have spent an incredible amount of time with toe in adjustment and different pads. I was able at one point for a couple weeks to get the squealing to stop. I never had this issue with the older versions. From what I can tell the issue is with the new dual pivot design. The right side seems to have more front / back flex than the left and odds are this is the issue. I had SRAM Red brakes and there was no squealing, however, while you can center them, they MOVE when the brake cable moves. The SRAM Red's are harder to center when change wheels unlike Shimano (D/A 9100) where no matter how tight the holding bolt is you can move by hand to re-center.

    • Familiarity: I've used it several times

    I recently changed the derailleurs on my Cervelo carbon soloist. I also added a cool carbon wheelset, but I couldn't use the original dura ace brake calipers as they were for a much narrower wheel. The new 9100 calipers work well they fit a much wider wheel set and seem to do the job. They were also easy to install.

    Pretty Dissapointing

    • Familiarity: I've put it through the wringer

    After upgrading to full DA 9100, this is the only piece that left me disappointed. The rear brake squeals after finagling, toeing in to different degrees, re-adjusting, etc. etc. The same issue exists with multiple wheel sets, and never was a problem with 2 different versions of Ultegra brakes prior. Aside from the noise issue, they also do not stay centered after hard use, and I have to continue to unscrew the centering bolt and re-adjust. Maybe they are X% stiffer and brake X% more powerful than the previous version of DA, but the new design seems to have sacrificed other qualities unfortunately.

    Same problem with the r8000 front right brake pad sqweeling. Direct mount just won’t adjust correctly

    Second to None

      The previous generation BR-9000 brakes were already the benchmark for the entire industry, and somehow Shimano has improved on it. They have added a steel bridge that stiffens the caliper further. There is no better brake out there on the market for power or modulation. Not officially compatible with SRAM or Campagnolo as Shimano uses a different pull ratio, but there are plenty of folks who run the setup with no ill effects
