Quality rotor for excellent brakes

2017 Specialized Roubaix just passed 38,000 miles and this is the third back rotor for the bike. I live in Sparks, Nevada, and enjoy many significant downhill decents in the area. Good braking is a necesity when decending from Ebbetts and Monitor Passes, and I find these rotors prevent brake fade. I weigh 200 lbs and the back rotor is only 140 mm so it gets severly punished. I stayed with the Dura Ace model as I prefer black to the silver of the Ultegra version. It will last for several years so I am willing to pay a little extra. Overall a good rotor.

A major improvement over original disc

Replaced my Ultegra discs with these new version Shimano Dura Ace discs after Ultegra disc were used up.
These Dura Ace disc were absolutely flat, no variation from true within the brake pads.
Very pleased with their performance.

Better then old Dura Ace

These don't seem to suffer from the heat warp that the old dura ace rotors did. They are great

Top notch looks and performance with the latest Dura-Ace rotor
Great and lightweight Dura-Ace rotor. Seems to have an improved design to prevent warping, though I haven't experienced any warping on prior generations. Great quality as always from Shimano
