Shimano XTR BR-M9220 Disc Brake Caliper

Shimano XTR cutting edge braking technology, lightweight and powerful easily adaptable post-style 4-piston hydraulic disc brake caliper.

High consistency and control make the BR-M9220 the strongest caliper in the M9200 family. New low viscosity oil keep the M9220 brakes’ bite point consistent in all trail and weather conditions, and new brake pads eliminate rattling noise caused by vibration. Increased power and consistency coupled with the peace of silence give riders pin-point control on rough trails.

Technology

Ice Technologies

Shimano Ice Technologies components deliver more consistent braking performance by reducing heat buildup in the system. This helps prevent brake fade, which can happen when a rider applies the brakes repeatedly and strongly over a short period of time, such as when descending a long, steep hill.

Shimano has adopted Ice Technologies disc brake rotor and Ice Technologies pad to realize the cooling technology for consistent performance. The clad disc brake rotor blade, which has a 3 layer-sandwich structure of stainless steel, aluminium and stainless steel, provides better radiation performance. Also, the radiation fin has been adopted for the pad. Moreover, the clad disc brake rotor blade and the radiator fin provide long pad life, less noise, less fade and lightweight.

Clad rotors as well as Clad Brake pads significantly reduce heat build-up in the brake system. This in turn reduces fading, which ensures consistent high performance even on long downhill stretches, It also results in a longer pad life and substantially quieter braking.

Four Piston

Disc brake system with the dual diameter opposed-piston caliper design has differently sized pistons in front and in the rear. The system adopts a power transfer system in which the disc brake rotor is pressed by the smaller sized piston at the entrance of the disc brake rotor intake and also by the more powerful larger sized piston at the back. This prevents the wobbling motion of the disc brake rotor and reduces noises significantly.

The 4-piston caliper also allows a wider contact area for the disc brake rotor while keeping the size compact, and the efficient location of pads is adjusted as necessary to stabilize the pressure. In combination use with the Servo Wave lever it provides an incredible 50% more stopping power than the previous model. The advanced Saint / Zee disc brake system, which adjusts to accommodate the different braking styles of different riders, offers stable braking power and excellent modulation.

• Dual diameter opposed 4-piston caliper design
• Offers stable braking power and excellent modulation, and disturbs the wobbling motion of the rotor and reduces noises significantly
