Rotor Disc SH RT-CL900 S 160mm External Spline 03015380

The Shimano RT-CL900 is a top model disc rotor designed to achieve maximum performance and control. It uses advanced ICE Technologies Freeza – a three-layer construction of stainless steel and aluminum that significantly reduces operating temperature and ensures consistent braking power even on long descents.

The new aluminum spider design provides improved resistance to deformation and significantly quieter operation compared to previous generations. The Center-Lock mounting makes installation and removal easier, offering secure and stable attachment.

The RT-CL900 is compatible with all types of brake pads – both organic and metallic – and is available in various sizes for different needs and riding styles. A perfect choice for road, gravel, and cross-country bikes.
