Shimano RT-CL900 Disc Brake Rotor 2026 size 180mm | Aluminum

evo.com | Shimano Rotors > The Shimano RT-CL900 Disc Brake Rotor pairs whisper-quiet operation with serious stopping power thanks to its heat-fighting Ice-Tech Freeza design. This rotor handles steep downhills while keeping its cool on long, brake-dragging descents. Center Lock System The CENTER LOCK system makes an easy rotor installation possible with spline mount and a lock ring, enhancing precision and rigidity while improving braking efficiency. 3D Aluminum Carrier Optimized 3D-shaped aluminum carrier is designed purposefully in every dimension for superb heat distortion resistance. This prevents the entire rotor from deforming due to heat and reduces rubbing noise while riding. Heat Dissipation Paint Ice-Tech Freeza Braking Technology ICE TECHNOLOGIES FREEZA rotors utilize the 3-layer stainless steel-aluminum-stainless steel sandwich structure to reduce heat buildup. The inner aluminum layer extends inward with a wide exposed radiator fin that boosts its cooling capabilities. | Shimano RT-CL900 Disc Brake Rotor 2026 - 180mm | Aluminum
