The Shimano Dura-Ace RT-CL900 Rotordelivers ultra-quiet and consistent braking performance, no matter the terrain. Designed to reduce heat deformation, this rotor helps maintain braking stability and controleven on long, steep descents. Its lightweight construction and precision engineering ensure that it performs at the highest level without adding unnecessary bulk. Whether you’re road racing, hitting gravel routes, or descending mountain trails, the RT-CL900 delivers the smooth, reliable braking Shimano is known for.

The rotors new, more robust arm shape reduces vibration, which results in quieter operation across all riding conditions. It also features a special heat dissipation paint that enhances thermal control, improving overall braking efficiency. Available in multiple sizes and including an internal serration lock ring for easy setup, this rotor is an ideal upgrade for cyclists who demand quiet, powerful, and consistent braking in all environments.

Key Features:

• Heat Dissipation Technology Reduces heat buildup for reliable braking on long, steep descents.

• Low-Noise Performance Robust arm design minimizes vibration and noise.

• Enhanced Durability Heat dissipation paint and lock ring improve performance and ease of installation.
