BR-R9270 Dura-Ace Hydraulic Disc Brake

Product Information

The Shimano Dura-Ace BR-R9270 hydraulic disc brake caliper represents a significant leap in braking performance, designed for demanding road cycling. Its innovative one-piece Mono-Body construction minimizes weight while enhancing stiffness, ensuring exceptionally direct and consistent lever feel even under hard braking. The caliper's refined design also addresses common rider concerns, offering a quieter and more reliable experience.

This high-performance brake system is engineered for those who prioritize control and efficiency, particularly for aggressive road riding and racing where every bit of stopping power and modulation counts. It seamlessly integrates with the 12-speed Dura-Ace R9200 series, providing superior heat management and easier maintenance.
