SHIMANO BR-R9270 (DURA-ACE)｜The pinnacle disc brake caliper, refined for stopping power and control

To ride fast, you must decelerate reliably. The next-generation disc brake DURA-ACE has pursued.

The SHIMANO DURA-ACE R9200 series "BR-R9270" is a hydraulic disc brake caliper that achieves the high stopping power and excellent control performance required in racing.

Its monobody (one-piece molded) structure maximizes rigidity while achieving lightweight design. It directly translates rider input into stopping power, providing stable braking performance even when entering corners or descending at high speeds.

Furthermore, the pad clearance has been increased by approximately 10% compared to conventional models. This reduces rubbing against the rotor and improves quietness and maintainability. It is a flagship-grade disc brake caliper that combines DURA-ACE's characteristic lightness with precise control performance.

The braking performance of the R9200 generation DURA-ACE feels incredibly complete.

Beyond simple stopping power, the control over lever input is excellent, providing a sense of security when entering corners or descending at high speeds. It feels like the bike naturally decelerates proportionally to how much the brake is squeezed.

Additionally, the reduced occurrence of rotor rub is a significant practical improvement. It means less frequent adjustment is needed after wheel changes or long rides.

It is a flagship caliper worthy of DURA-ACE, achieving a high-level balance between lightness and braking performance.
