Comes with lock ring and washer

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.

It works. I have no issues with the Shimano Ultegra RT-CL800 Disc Rotor thus far.

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

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.

Stop me every single time.

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.
