Shimano's RT-MT800 brake rotor stands for great heat dissipation


The Shimano RT-MT800 external serration brake rotor with lockring reduces temperatures even further through Ice Technologies FREEZA heat dissipation, resulting in more consistent braking performance. The life of the brake pads is also extended. The RT-MT800's proven sandwich construction with an aluminium core between two layers of stainless steel ensures efficient heat dissipation via the integrated radiation fins.

Technology:

Ice Tech FREEZA
Shimano Ice Technologies provide a fast heat dissipation at your disc brake. The brake pads are equipped with aluminium cooling fins. The brake rotor is constructed using a sandwich technique in which stainless steel encloses an aluminium core. The stainless steel on both flanks ensures long durability, the aluminium allows heat dissipation. FREEZA is the further development of the brake rotor, in which additional ribs in the aluminium provide even better heat compensation. This cooling technology creates consistently high performance and longer brake pad durability while reducing fading and brake noise.

Meine vordere Scheibe hab ich jetzt nach 5200km wechseln müssen, da Verschleissmaß erreicht. Klasse: Hat zwar gebremst wie immer, aber mehr und mehr Geräusche gemacht (Verschleissindikator?) , dachte es läge an den neuerdings montierten Sinterbelägen...bin jetzt wieder bei Resin zurück, da ich glaube, dass der Verschleiss mit diesen geringer ist.
