Description For the first time, NEW Dura-Ace employs a front and rear specific system that is more powerful and lighter than the original Dual Pivot design.
Bike Setup: Klein Quantum. Mavic SSC/SL wheels. Mix of campy and shimano components.
Summary: I can not believe the improvement in stopping since switching to these brakes. I replaced a vintage set of Suntour Superbe Pro's that I had held on to for too long for sentimental reasons. My least favorite 15 percent downhill has now become my favorite, allowing me to confidently spin up to speed and quickly bleed it back off heading into the corners. I replaced the stock pads with Kool Stop Salmon's, and surprisingly I think the stock Shimano pads are actually better. In any case the Kool Stops are at best over-rated.
Strengths: Strong braking. Light weight. Easy to install and adjust.
Weaknesses: None so far.

Summary: Not a lot to say, its a brake, they aren't that complicated. Great stopping power, light weight. severely limited tire options. If you want the name... its a very effective product. If you don't care about the name, ultegra worked almsot exactly the same and I had less clearance issues with the ultegra.
Strengths: Like i said in the summary, light weight great stopping power.
Weaknesses: Very narrow clearence for the tire. With the caliper open, a 23mm tire can be force in and out without much difficulty but i can't run a 25 on it. Not as easily dismantled as some other brakes, so overhauls can be difficult. Probably easier to just throw it in the parts cleaner or spray it down with triflow rather than rebuilding it.

Bike Setup: VERY high end.. Carbon/Scandium frame, Look HSC4 fork, Carbon SLK cranks, Various wheels including Ksyrium SL, Dura Ace hubs and solid rims Dura Ace shifters..
Summary: I bought these thinking that they were on sale for a ludicrously low price... When I got them, the company sent me one caliper when they advertised break set! Anyway, they made it as right as they could, so that is that..
As far as the actual product goes, I was totally floored as to how much better my bike stopped with these calipers as opposed to the Ultegra calipers (even with the long pads on them) There is an issue with the release lever, especially if one rides in the weather... HOWEVER, if you keep it lubed, it should not cause more than annoyance.
Strengths: Superior breaking power!
Weaknesses: for the price, I am not sure they are actually worth it... Ultegra breaks almost as well, and I am about to try the FSA SLK along with Cannondale's C1 carbon breaks shortly.. Check those after I check them out!
Similar Products Used: Ultegra, 105, Campy Centaur, Chorus, Record. I like shimano better due to the easier release mechanism, though the campy stuff stops just as well..

Summary: Just bought a new Giant TCR Comp 0 with Dura Ace. Old bike had 9 speed Ultegra. The Dura Ace calipers are much stiffer. On a 45 mph descent with a stop sign at the bottom, I was extremely impressed with the performance. They modulated well & didn't require near the same amount of lever force that the Ultegras do.
Strengths: Confidence Inspiring braking.
Weaknesses: None found.
Similar Products Used: Ultegra 9 speed.
Campy Athena.
old Diacompe brakes.
