Shimano Dura-Ace RT-CL900 203 mm internal with magnet Brake Disc

The Shimano Dura-Ace RT-CL900 203mm inner disc brake comes with a focus on decreasing disc thermal deformation, the result of the new disc brake is quieter performance without sacrificing weight or heat dissipation. The three-dimensionally optimised aluminium bracket is purposely designed in each and every dimension and achieves light weight and superb resistance to thermal distortion.

This prevents the entire disc from deforming due to heat and reduces friction noise during driving.
