Shimano Dura-Ace RT-CL900 Disc Center Lock

The Shimano Dura-Ace RT-CL900 Ice-Tech Freeza brake disc represents the pinnacle of technology for cyclists who demand high-level performance. Here is an overview of its main features:

Main features:

• Center Lock Design: Center Lock design allows for simple and secure installation on the wheel hub.

• Ice-Tech Freeza Technology: This technology focuses on reducing the thermal deformation of the rotor, ensuring consistent and reliable performance even during the longest or steepest descents. This helps keep the brake disc quieter and reduces the possibility of overheating.

• Lightweight: While offering excellent heat dispersion, the Dura-Ace RT-CL900 Ice-Tech Freeza disc is designed to be lightweight, thus contributing to greater agility and responsiveness of the bicycle.

Ice-Tech Technology:

• Three-Layer Structure: Ice-Tech technology uses a three-layer structure, consisting of two layers of stainless steel sandwiched with an aluminum core. This design improves the disc's ability to dissipate heat efficiently, thus reducing the risk of overheating and improving braking performance.

• Cooling Fins: The disc features cooling fins that further increase heat dissipation capacity, helping to maintain consistent brake performance even during intensive use.

Installation and Compatibility:

• The Shimano Dura-Ace RT-CL900 Ice-Tech Freeza brake disc is compatible with the Center Lock mounting system, ensuring quick and secure installation on a wide range of bicycle wheel hubs.

Recommended Use:

• This brake disc is designed for use on road bicycles and offers exceptional performance for both professional cyclists and enthusiasts looking for maximum performance and reliability during the most demanding descents.

In conclusion, the Shimano Dura-Ace RT-CL900 Ice-Tech Freeza brake disc offers an excellent combination of braking performance, lightness and heat resistance, ensuring a safe and comfortable ride even in the most extreme conditions.

ICE TECHNOLOGIES FREEZA
The Freeza technology disc brake rotor quickly dissipates heat for more consistent braking performance in extreme conditions, offering long pad life, lower efficiency losses and lower noise. The lightweight and very efficient three-layer stainless steel / aluminum / stainless steel sandwich structure improves heat dissipation.

CENTER LOCK
The Center Lock system makes possible simplified rotor installation with key couplings and retaining ring. Stop ring mounting system reduces total labor hours and installation and de-installation times. Furthermore, the solid fastening via key couplings enhances precision and rigidity while increasing braking efficiency.
