Ice-Tech is Shimano's approach to high-performance braking by reducing operating temperatures. Ice-Tech rotors are a two-piece floating design for increased stiffness and they feature a 3-layer construction.  There's an aluminium core sandwiched between two stainless steel outer layers.  Aluminium dissipates heat quickly which works perfectly for braking.  When combined with Shimano brakes and Ice-Tech pads, riders will notice consistent performance, reduced brake fade and less brake noise. 
If you are replacing rotors or looking to upgrade, these should be a strong contender.
