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.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+.http://cycle.shimano-eu.com/publish/content/global_cycle/en/nl/index/news_and_info/Velotech_Disc_Brake_Test.image.-Par70parsys-0014-image.dash.550.290.pngVelotech.de disc brake testGreat performance results for Shimano Ice-Tech disc brakes during comparison test in renowned Test-instituteShimano introduced a revolutionary cooling technology for disc brakes in 2010 named ICE TECHNOLOGIES.

Enjoy the ride !!!!
BosRot Posted February 21, 2011 Posted February 21, 2011 These new XTR disc brakes were tested in a recent German magazine. 'BIKE' they performed miserably ! In fact in the test these brakes failed !The test conditions were extreme - however all the other manufacturers tested faced the same conditions without failing. Due to this test you will find a couple of XTR specked bikes without XTR brakes !My suggestion is stay away unless you are a XC rider ! See this video link: http://video.bike-magazin.de/bikeclips/testScheibenbremsentest 2010 - Disc Brake Test 2010Sorry test is in German but look at the video. SHIMANO PR comment: Conditions were too extreme Comment from Bike Magazine: Conditions were extreme however others did not fail
Palaeodom Posted February 21, 2011 Posted February 21, 2011 There will always be a test that can break anything. look at Top Gear for example. They often break a number of examples of some of the most expensive high performance vehicles on the planet when they do a test drives, it wouldn't necessarily be because of the extreme nature of the driving or a particularly bad product... The only thing that's clear is that lots of tests are needed to get an average performance.
