The Shimano XT/Ultegra RT-CL800 disc brake rotor provides smooth, quiet braking. Its Ice-Tech Freeza construction helps dissipate heat efficiently, especially on long, steep descents.
ICE TECHNOLOGIES FREEZA – Combined with FREEZA disc brake rotor construction, this technology rapidly dissipates heat for more consistent braking in extreme conditions, longer pad life, and less brake fade and noise. The lightweight, efficient three-layer sandwich structure of stainless steel, aluminum and stainless steel enhances heat dissipation.
CENTER LOCK – This system allows easy rotor installation with a spline mount and lock ring. The lock-ring mounting system reduces total working time by shortening both installation and removal. The secure spline mount also improves precision and rigidity while enhancing braking efficiency.
