Less Noise on Fast Descents Engineered for sustained braking on high-speed descents, this Dura-Ace rotor manages heat to reduce deformation for quieter, more consistent braking. An updated arm profile and heat-dissipating paint maintain performance without adding weight. Features Improved Heat Management: Designed to limit heat-related distortion, supporting consistent braking under sustained load Quieter Brake Performance: Revised rotor arm shape increases stiffness, helping minimize vibration and noise ICE TECHNOLOGIES FREEZA Cooling: Painted radiator fins deliver exceptional heat dissipation during prolonged braking Consistent Braking Control: Designed to deliver a stable braking feel without compromising weight or performance Multiple Rotor Sizes: Available in 140, 160, 180, and 203 mm to suit a wide range of riding needs Quieter Sustained Braking Reduces heat deformation under sustained braking to keep performance quiet and consistent, delivering smoother modulation and predictable lever feel for confident control on long, fast descents and tight corners. Built to Shed Heat An updated rotor design combines a more robust arm shape with heat-dissipating paint to improve cooling efficiency. This helps maintain stable braking performance and reduces noise during repeated and sustained braking.
