Added these rotors to a new wheelset I was running these rotors on my "stock" setup, and I have found them to be very reliable. They were easy to install, and they work just as I had expected. Reliable, Shimano quality. No issues.

Compatible with my 105 system. Easy to install. These rotors work exactly as they are supposed to�.I have yet to crash because the brakes did not brake. They look aero too. Probably made me faster. Probably saved me 0.125 watts. Zoom.

The rotor is great, got them to add to a set of Shimano carbon wheels. Lined up perfectly, strong, quiet braking. The description doesn't mention it, but you do get the lock ring and washer with it.

Newest Gen Shimano Rotors a Decent Upgrade

These new ultegra rotors seem to do better in the crosswinds and on the noise compared to my old Ultegra. They seem less susceptible to fade as well on long descents. Recommended if you're updating brake pads or calipers.

The rotors are used on an All-Road bike, mainly go on (pavement) trails and on occasions off-road on hardpack gravel.
