SHIMANO RT-CL700 Disc Brake Rotor Quieter braking, better heat management, with an updated alloy carrier The SHIMANO RT-CL700 is an ICE TECHNOLOGIES disc brake rotor that's designed to keep braking consistent on long descents, while reducing noise and heat-related rotor issues. An updated 3D-shaped aluminum carrier is engineered to improve heat management and help minimize rubbing and resonance (noisy braking), while the centerlock rotor interface simplifies installation and removal with the increasingly-popular lockring system. Positioned just below SHIMANO's top-tier rotor models, the RT-CL700 is a solid upgrade for riders who want a refined feel, improved thermal performance, and quick serviceability across a range of common rotor diameters.
