The design of the Shimano XTR / Dura Ace RT-MT900 disc brake rotors is a further development of the successful ICE TECHNOLOGIES FREEZA design. While the further weight reduction of 5g and 10g is particularly attractive for the 140mm and 160mm discs, the 180mm and 203mm versions are characterised by a further improvement in heat dissipation of 20°C in intensive tests and are also pleasantly low-weight (203mm: minus 30g).
