Disc Rotor Shimano RT-CL900 Center Lock

Disc Rotor Shimano RT-CL900 Center Lock

The SHIMANO RT-CL900 disc rotor combines a compact and lightweight design with top-tier braking performance for demanding road, gravel, and mountain riders. Used in Dura-Ace, GRX, and XTR groupsets, it delivers maximum control and consistent stopping power in all riding situations.

Featuring the updated ICE TECHNOLOGIES FREEZA heat management system, the rotor provides exceptionally fast and efficient heat dissipation. This reduces brake fade on long descents and maintains stable, predictable braking performance under heavy loads, ensuring confidence during races and intense training sessions.

The SHIMANO CENTER LOCK mounting system allows for quick and easy installation and removal. Precise spline engagement ensures optimal stiffness, reduced vibration, and efficient braking force transfer. The 140 mm and 160 mm sizes are ideal for road and gravel use, while larger options suit more demanding off-road applications.
