Shimano RT-CL900 Center-Lock Disc Rotor
Please select a variant to check compatibility
Product information "RT-CL900 Center-Lock Disc Rotor"
SHIMANOs compact and lightweight RT-CL900 brake discs feature particularly fast heat dissipation thanks to ICE TECHNOLOGIES FREEZA heat management system. SHIMANOs CENTER LOCK design makes the installation and removal of brake discs very easy.

Ice-Tech FREEZA
SHIMANO’s ICE TECHNOLOGIES has realized the ultimate clad rotor, incorporating aluminum fins for enhanced heat control. With an increased surface area for heat dispersion, the rotor achieves a 50°C reduction in heat. This in turn generates a 20% increase in braking force durability and a 20% longer pad life.
Center-Lock System
The CENTER LOCK system makes an easy rotor installation possible with spline mount and a lock ring. The lock ring mounting system reduces the total working hours by shortening the amount of time of both installation and de-installation. In addition, the secure fixing by the spline mount enhances precision and rigidity while improving braking efficiency.
