Shimano RT-CL900 Disc Rotor - Internal Spline Type Info

The Shimano RT-CL900 Disc Rotor - Internal Spline Type sits at the top of Shimano's road disc brake hierarchy, bringing Dura-Ace-level engineering to riders who demand reliable, quiet stopping power in every condition. Its updated arm geometry is designed to reduce noise at the source — not mask it — while the rotor's construction prioritizes heat dissipation on long, loaded descents where brake fade becomes a real concern. Mount it via the Center Lock internal spline interface for a secure, precise fit that eliminates the play you sometimes find with less refined mounting systems.

Available in 140mm and 160mm diameters, the RT-CL900 gives you the option to match rotor size to your riding — 160mm for more aggressive stopping power on longer descents or heavier riders, 140mm where weight and clearance are the priority. Both sizes share the same rotor design and Center Lock compatibility.
