I run Ultegra callipers on Centreline clx rotors and they’re much more quiet than the Dura Ace ones I took off. The Shimano ones had a real warble to them as they’re alu cores which go out of true easily and make the noise.
Cool, also have Dura ace rotors and haven’t been happy with them, both were delivered out of true and they’re noisy in the wet (although haven’t tried w resin pads). No need for ice-tech alu cores here so centerline XR seems like a better choice and equally important, they look better IMO.
I wonder if the uneven track width of the dura ace rotors contribute to warble? I measured them 9.5 mm at the narrowest and 15 mm at the widest, whereas centerlines are around 15 mm even (shimano pads are 13.5mm tall).
