Can anyone provide advice on cross compatibility for Shimano rotors? My gravel bike has Shimano SM-RT99-A-SS IceTech Disc Brake Rotor - Centerlock - 140mm. They’re quite below spec for thickness after 15k+. These are proving a bit hard to find. If I go with another 140mm center lock Shimano, such as the Ultegra, will they be compatible? I expect to need to open up the calipers and likely reposition the brakes themselves, but I just wonder about the distance from the center lock seating on the hub and the location of the rotor itself.
Many thanks for any advice from someone more knowledgeable.
Thanks for the reply. The pads are pretty fresh. I’ve been riding these 140s since new and never have had any braking problems…I’m not particularly heavy. My road bike has 160s, which is nice, though! I appreciate the tips.
