Shimano RT-MT800 Center-Lock Disc Rotor
Shimano RT-MT800 Center-Lock Disc Rotor
The design of the Shimano XT / Ultegra / GRX RT-MT800 disc brake rotors is a further development of the successful ICE TECHNOLOGIES FREEZA design.
** only compatible with 140mm and 160mm
Technologies
Ice-Tech FREEZA
SHIMANO’s ICE TECHNOLOGIES has realized the ultimate clad rotor, incorporating aluminum fins for enhanced heat control. With an increased surface area for heat dispersion, the rotor achieves a 50°C reduction in heat. This in turn generates a 20% increase in braking force durability and a 20% longer pad life.
Center-Lock System
The CENTER LOCK system makes an easy rotor installation possible with spline mount and a lock ring. The lock ring mounting system reduces the total working hours by shortening the amount of time of both installation and de-installation. In addition, the secure fixing by the spline mount enhances precision and rigidity while improving braking efficiency.

Great rotors. Great braking. Took for a trekking bike with 28 inch wheels.
Super Bremskraft und Kühlung. In der Tat ist die Kühlung so gut, dass bei kürzeren Abfahrten die Bremse gar nicht wirklich warm wird. Spürbar an anfangs lauterem Geräusch und weniger Power an meiner SLX 4-Kolbenbremse.
Mit die beste Idee die Bremse aufzurüsten. Bringt echt viel vor allem wenn man zu den schwereren Bikern gehört.
Hat alles perfekt geklappt. Ich brauche bitte eine Rechnung für diesen Kauf.
sehr gute Bremsleistung
