The RT-CL900 is Dura-Ace's flagship disc rotor. Ice-Tech Freeza construction with radiator fins takes heat dissipation further than Ultegra, and the finish quality is a class above. For riders who want the best braking feel Shimano offers on a road bike, this is the rotor to fit.

- 160mm diameter (also check 140mm option)
- Best-in-class heat dissipation, noticeable on long descents
- Center Lock mounting, compatible with all standard Center Lock hubs
- Flagship-quality braking feel and modulation
Fitment: Center Lock hub required. Lockring sold separately if needed.
Ideal for: Riders building or upgrading a Dura-Ace/flagship road or gravel bike.
