Premium braking consistency and ultimate heat dissipation for elite riders

Engineered for road riders who demand absolute control, the Shimano Dura-Ace RT-CL900 rotor delivers unmatched stopping power and thermal management. Designed to perform under the heaviest braking loads—such as long, steep alpine descents—this rotor minimizes heat build-up to prevent brake fade and maintain a consistent lever feel.

By utilizing Shimano's advanced Ice-Technologies Freeza sandwich construction (stainless steel/aluminum/stainless steel) paired with a specialized heat-dissipating coating, this rotor sheds heat incredibly fast. The result is a quieter ride, less wear on your pads, and confidence-inspiring braking performance in any weather.

• Ice-Tech Freeza Tech: Sandwich structure with an aluminum core that effectively channels heat away from the braking surface.
• Thermal-Coated Fins: Features specialized paint on the cooling fins to accelerate heat dissipation.
• Center Lock System: Easy, secure, and precise installation on your hub with the included lightweight aluminum lockring.
• Noise-Reduction Design: Specifically engineered to reduce rotor deformation from heat, preventing rubbing and squealing.
• Pad Compatibility: Fully compatible with both resin (organic) and metal (sintered) brake pads.
• Featherweight Build: Weighing approximately 114g, it offers elite-level performance without a weight penalty.
