The Shimano XTR BR-M9120 disc brake caliper is a top-tier component in Shimano's lineup, engineered for both front and rear applications. It features an innovative MONO-BODY design, precision machined from a single block of material to achieve maximum rigidity, which is essential for consistent, high-performance braking.

Equipped with four ceramic pistons, the caliper offers exceptional stopping power tailored to the rider's needs. This design ensures a high level of heat resistance and a responsive braking feel. Compared to its predecessor, the BR-M9000, the BR-M9120 achieves a 30% reduction in time lag and a 10% increase in braking power over the BR-M9020 model, indicating significant advancements in brake engagement and overall performance.

The caliper utilizes a banjo-type connection for the hydraulic hose, which allows for flexible routing within the bike frame, contributing to a cleaner and more aerodynamic profile.

Included with this caliper are Shimano's N04C-MF metal finned brake pads, renowned for their excellent heat dissipation properties, which help to maintain optimal braking performance during long descents and in high-temperature conditions.

The system operates with mineral oil hydraulic fluid, chosen for its stable performance characteristics and low maintenance. With a weight of approximately 262 grams, the XTR BR-M9120 caliper is both lightweight and durable, without including a rotor to provide riders the option to select one that best fits their riding style and bike specifications.
