Shimano Dura-Ace RT-CL900 Centerlock Rotor 140mm Ice-Tech Freeza | Technical Excellence and Superior Thermal Performance

In professional road cycling and high-end gravel riding, braking performance is the most critical component of safety and control. Shimano's flagship brand... The Dura-Ace RT-CL900 Centerlock Rotor is more than just a brake disc; it's an engineering marvel and a revolution in thermal management. Equipped with "Ice-Tech Freeza" technology, this rotor promises unwavering braking power, smooth modulation, and minimal noise levels, even on long and steep descents. Here's a comprehensive product description that will help you rank higher in search engines and allow your customers to see all the technical details in full:

🏆 Technological Revolution: Ice-Tech Freeza and Sandwich Construction

At the heart of the Shimano RT-CL900 is a system that takes heat from being an enemy of the brakes and brings it under control. Ice-Tech Freeza It has a thermal management system. This system is a special three-layered system. "Sandwich Construction" It comes to life with (Stainless Steel - Aluminum - Stainless Steel). This structure quickly dissipates the intense heat generated by braking away from the disc surface and drum area thanks to the excellent thermal conductivity of the aluminum core. The result? A significant decrease in disk surface temperature.

🔬 What this technology offers you:

• Minimizing Brake Fading: Braking performance does not decrease during long descents; it remains consistent and reliable.

• Superior Brake Modulation: The "on/off" sensation caused by heating is eliminated, and precise and delicate brake force control is achieved.

• Reduced Brake Noise: Vibrations and creaking caused by the expansion of discs due to heat are largely prevented.

• Extending Brake Pad Life: Lower operating temperatures slow down the rate of brake pad wear.

⚙️ Advanced Mechanical Design: Durability and Silence

Shimano engineers optimized the RT-CL900 not only thermally but also mechanically. Alloy carrier (spider) reinforced. And The sleeve shape has been redesigned. These improvements eliminate the risk of deformation that can result from overheating, while allowing the disc to rotate more smoothly and therefore... a quieter braking experience It enables it to present.
