Shimano's new ICE tech fabrication process sandwiches an aluminum rotor core in stainless steel to offer superior heat dissipation and keep weight at a minimum. In independent tests preformed by Germany's Velotech.de, ICE tech rotors outperformed even their Saint predecessors. Pilots of Saint-equipped bikes will be glad to know that the new XT ICE tech rotors are compatible with older Shimano braking systems for a significant improvement in performance.
These rotors are only compatible with Centerlock disc hubs.
