Shimano BR-M9100 XTR Disc Brake Set J-KIT

The Shimano BR-M9100 XTR Disc Brake Set J-KIT is engineered for top-tier performance, featuring the BL-M9100 brake lever and BR-M9100 2-piston caliper. This set delivers exceptional stopping power and control, with the caliper’s Mono-body design and ceramic pistons offering precise, Rider-Tuned braking. The lightweight design includes a magnesium master cylinder and carbon levers, reducing weight while enhancing braking efficiency. The two-piston caliper excels in cross-country racing, boasting a 10% increase in stiffness and compatibility with Shimano’s I-Spec EV system for improved rigidity and response.

Shimano's M9100 series maintains the XTR range’s high-performance legacy with a sleek, minimalist design. Unlike the heavier M9120, the M9100 focuses on a lightweight setup for XC riders, optimized for use with Shimano’s IceTec Freeza rotors for rapid heat dissipation and consistent performance at high speeds.
