The concept of the Shimano XTR RT-MT900 brake disc rotors is a further development of the successful Ice-Technologies Freeza design.
While the 140 mm disc in particular represents a further weight reduction of 10 grams, the 180 and 203 mm versions stood out in intensive tests due to a further improvement in heat dissipation of 20 °C and are also pleasantly restrained on the scales.
This effective heat management during braking is achieved not least by the sandwich construction (stainless steel - aluminium - stainless steel) which improves and stabilises the braking performance. The result is first-class and consistent braking performance even in the most demanding conditions.
Version with integrated magnet for use with the STePS EW-SS302 speed sensor (not included).
