Shimano XTR RT-CL900 Ice-Tech Centerlock Disc Rotor - 203mm - Centrelock - Standard - 1.8mm to 1.9mm - External Serration PLP|Colour 2 41mm OD External BBWhen developing the XTR CL900 brake rotors, Shimano engineers succeeded in preventing heat related deformation of the rotors. As a result, the CL900 rotors offer more reliable, more controllable braking performance and are quieter than ever before. Fortunately, the weight has remained at the same low level as the previous version. Also on board is Shimano's Ice Tech cooling technology, which ensures excellent heat dissipation and constant braking
