The Shimano XTR BR-M9100 Disc Brake Caliper is engineered with a MONO-BODY design, machined from a single cold-forged block to enhance rigidity. It features dual ceramic pistons for precise, Rider-Tuned braking performance.

With increased braking power and reduced input force at the fingertips, the caliper offers a highly responsive linear feel. Compared to the BR-M9000, it boasts a 30% reduction in time lag. Its high-rigidity brake hose and one-piece aluminum caliper contribute to optimal performance. The caliper also includes K04Ti metallic pads for enhanced durability and stopping power.
