SM-RT900 Center Lock | IceTech Freeza
Shimano Ice-Tech is a cooling technology that ensures maximum consistent braking performance. The brake disc is characterized by its three-layer sandwich construction made of stainless steel edges with an aluminum core and has a substantially improved heat dissipation. Thus, the temperature can be reduced by around 100 ° C.
The new Dura Ace Freeza rotors also have aluminum fins, which can reduce the system temperature by another 50 ° C by their increased surface area.
For fast and easy installation, secure grip and a clean and compact appearance, the discs with a center-lock mount equipped.
The new Dura Ace crankset is characterized by a very high switching performance. The gearshifts are doing with high precision.
