ShimanoUltegra RT-CL800 Disc Rotor(Return to Product Page)

Thought I had a warped rotor, but I was wrong.While I was waiting for the Ultra rotor to arrive I carefully cleaned the old 105 rotor which fixed the pulsing issue. Since the Ultra rotor had arrived, I went ahead and put it on. Easy installation, you use the same tool as the you use to take off the freehub.

Does it work better than the 105? Who knows? Either one stops the bike. Kinda looks nicer, though.

Great product + Good sale price = GO!

Product does what it is supposed to do and looks good doing it.

Have had these on multiple bikes for thousands of miles with no complaints.

My road bike rotors were getting thin enough to replace. My bike shop recommended I shop online and bring them in. It was cheaper and fast to order through Bike Tires Direct than for my LBS to order. They arrived quickly and exactly the part needed to replace on my Specialized bike.

Needed a set of rotors for my second wheelset. I wanted to keep the components the same. Excellent rotors.

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.

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.

Replaced my gravel bike shimano disc brake rotors with these. Work great. Nice and quiet and quick stopping. Easy to install.

Perfect replacement for my GRX rotor

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.

Great rotor for the front wheel.

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.

Now I can stop on hills changing from 140 dia to 160 dia.
