Shimano Dura-ace RT-CL900 Disc Rotor Ice-tech Center Lock Internal Serration W/lockring

The RT-CL900 Center Lock brake rotor was specially developed by Shimano for the Dura-Ace BR-R9270 road bike disc brake. Apart from that, it is also compatible with numerous brake calipers from the gravel or MTB sector. The brake rotor features a sandwich construction with an aluminium layer between two stainless steel layers. Thanks to Ice Technologies FREEZA and a special heat-dissipating coating, it won't overheat even on steep, long descents. In addition, the design has been optimised to keep noise and weight to a minimum. The RT-CL900 comes with a lockring with internal gear teeth, and can be used with both organic and sintered brake pads.
