I am looking for possible disc rotors for the GRX 2x11 that comes with the GRX BR-RX810 brakes but can just find one recommendation which are the Shimano Ultegra SM-RT800 Center Lock Ice-Tech, that I find very ugly. Even on the Shimano page I cannot find anything else. Are there any other rotors that are compatible with the GRX BR-RX810 and GRX2x11?

If you want to stick with Shimano, the line-up charts for the GRX groups suggest an SM-RT64, SM-RT70 and RT-MT800 for use with RX400 and RX600 and RX810 groups respectively. None of those discs have the 'bladed' look of the SM-RT800 rotor.


In all honesty, you can use any disc you like, and from practically any manufacturer as long as the dia. (and fitment type) is the same.

    There are some limitations, however. I had purchased some "pretty" Hope 2 piece rotors that had red anodized centers that cost me a pretty penny. They did not work even though they were the right size because they had rivets holding the outer rotor to the rotor center and the rivets stuck-out too far and hit the brake caliper. So just be careful when ordering a non Shimano part... make sure you can return whatever you buy if it doesn't fit! Commented Oct 14, 2019 at 12:34
  • Just to chime in, I have had a similar experience with higher end rotors with aluminum centers. Commented Oct 14, 2019 at 17:03
  • It's always that problem with any 'exotic' components that some are not compatible, mainly because they don't follow the exact specifications.
