Advanced Heat Management

Shimano’s Ice Technologies FREEZA is a state-of-the-art feature that significantly improves heat dissipation. The multi-layer rotor construction, consisting of an aluminum core sandwiched between stainless steel outer layers, effectively reduces heat build-up. This results in more consistent braking performance, especially on long descents, and extends pad life by preventing overheating.

Center Lock Mount System

The RT-CL800 uses Shimano’s Center Lock mounting system, which simplifies installation and removal of the rotor using a spline mount and lock ring. This design not only ensures a strong and secure fit but also reduces the possibility of rotor wobble, improving overall braking performance.

Enhanced Durability and Lightweight Design

Constructed to withstand rigorous use, the RT-CL800 rotor maintains high structural integrity without adding unnecessary weight to your bike. This balance of durability and lightness helps improve your ride quality and performance.

Sizes and Compatibility

• Available Sizes: 140mm, 160mm, 180mm, and 203mm diameters to suit different riding styles and preferences.
• Compatibility: Designed for use with Shimano hydraulic disc brake systems and Center Lock hubs.

SHIMANO Brake Disc Center Lock RT-MT900 | 140 mm IceTech FREEZA

With the Ice-Tech cooling technology, the RT-MT900 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 approx. Another 50 ° C due to their enlarged surface. Due to the higher heat dissipation, smaller brake discs can be installed than usual. In addition, the service life of the brake lining is significantly extended.
As is typical for Shimano, the discs are suitable for the center lock mount , which enables quick and easy assembly, 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.
