The design of the Shimano XTR RT-MT900 brake discs is a further development of the successful Ice-Technologies Freeza construction. While the improved weight reduction of 5 or 10 grams of the 140 or 160 mm discs represents a particular advance, the 180 and 203 mm versions were characterized in intensive tests by a further improvement in heat dissipation of 20 °C and are also pleasantly restrained on the scale (203 mm: minus 30 grams). This effective heat management while braking is achieved by the sandwich structure (stainless steel - aluminium - stainless steel) improving braking performance and reliability. The result is first-class and consistent braking even in the most demanding conditions.
