SHIMANO Center Lock RT-MT800 brake disc | 180mm IceTech FREEZA | with magnetic locking ring for EW-SS302
With the Ice-Tech cooling technology, the RT-MT800 brake disc ensures constant braking performance even on longer descents. The brake disc is characterized by a three-layer sandwich construction. The stainless steel flanks with an aluminum core offer significantly improved heat dissipation. This allows the temperature to be reduced by around 100 °C.
In addition, the FREEZA aluminum cooling fins reduce the system temperature by around a further 50 °C thanks to their increased surface area. Due to the higher heat dissipation, smaller brake discs than usual can be installed. In addition, the service life of the brake pad is significantly extended.
As is typical for Shimano, the discs are suitable for the center lock mount , which enables quick and easy installation, offers a secure hold and ensures a clean and compact look. A lighter aluminum carrier saves a few grams of weight compared to the previous version.
The magnet integrated in the lockring serves as a signal pickup for the Shimano Steps EW-SS302 speed sensor.
