Dura-Ace BR-9100 Brake Calipers

• 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.

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
