Shimano Ice Rotors
This is an article from Sicklines. com
"In order to test the limits of the Shimano XTR Ice-Tech rotors, Shimano solicited the help of Velotech to test the Saint as well as XTR brakes. See inside for the results from Shimano.
Shimano introduced a revolutionary cooling technology for disc brakes in 2010 named ICE TECHNOLOGIES. Since in any brake system there is a direct relation in between the generated kinetic energy (for brake power) and thermal energy (generated heat), Shimano has focused on the management of the system temperature. Lowering the temperature contributes to avoid negative effects on braking performance, as a result ICE TECHNOLOGIES brake systems have practically zero brake fading in normal usage, it increases the pad-durability up to 100% and reduces noise substantially.
XTR Trail brake with cooling fins and Ice Tech rotor
This technology basically consists of two elements. First of all, the rotors have a 3-layer sandwich structure of an aluminum core and two stainless steel outer layers; due to the higher heat dissipation of aluminum it reduces the rotor surface temperature with around 100 degrees. Secondly, the ICE TECHNOLOGIES brake pads that are recommended for trail riding feature aluminum cooling fins that can further improve the heat dissipation and reduce the brake-pad surface temperature by another 50 degrees.
The renowned German test institute "Velotech.de" has tested all SHIMANO XTR disc brakes in the previous weeks with striking results. They have tested the Cross-Country as well as the Trail version of the new XTR with different rotor-sizes and compared them to the famous SAINT brakes as well as with other high-end brands that are included in the usual magazine- tests regularly as well. You can check the details of the test results for the tested brake-models in the attached PDF's of the original "Velotech.de" certificates and test reports at the right side of this web page.
The result in short:
* All tested new SHIMANO XTR disc brake models/rotor sizes/pad combinations have exceeded Velotech's firm disc brake standards, as well as the DIN EN 14766 and GS standards. See the attached reports for the detailed data.
* The Ice-Tech brakes do withstand testing even under conditions that are 3 times as hard as required by DIN+.
* Even if trying to test until failure of the brake Ice-Tech brakes are far ahead of the other brands and do withstand the test under 1050 Watt, while even the famous SAINT brake cannot do that (as a tip for SAINT users we recommend the usage of Ice-Tech rotors as these will improve the system performance a lot!!!).
* Even if trying to test until failure of the brake Ice-Tech brakes are far ahead of the other brands and do withstand the test under 1050 Watt, while even the famous SAINT brake cannot do that (as a tip for SAINT users we recommend the usage of Ice-Tech rotors as these will improve the system performance a lot!!!).
Footnote:
* = marked brakes did complete the test without failure
** = the brake did fail in the 700W test already
The new XTR brakes work on a much lower temperature level than regular disc brake systems and do have practically no fading as you can see in the below chart
Shimano's Conclusion - The Ice-Tech system contributes a lot to the lifetime of your system and the reliability and stability of your brake performance. Enjoy the ride!
