With a focus on decreasing disc brake rotor heat deformation, the result of the new disc brake rotor is quieter than ever brake performance without sacrificing weight or heat dissipation.
• Quieter than ever, but with superb, consistent braking performance on any long, steep descents thanks to excellent heat dissipation • The new arm shape is more robust, leading to quieter operation • Disc brake rotor size: 140 mm, 160 mm, 180 mm, 203 mm
