The Shimano XTR BR-M9110 is a race-tuned 2-piston hydraulic disc brake calliper built for cross-country competition. Flat mount only, it combines featherlight anodised aluminium construction with ceramic pistons and Shimano's proven mineral oil hydraulics — delivering consistent, modular stopping power lap after lap.

Highlights

• 2-piston ceramic pistons: Heat-resistant ceramic pistons provide consistent feel and reduce fade during hard race efforts.
• One Way Bleeding: Shimano's optimised hose routing eliminates air traps in the hydraulic system, making bleeding faster, cleaner, and more reliable.
• K03Ti resin pads included: Titanium-backed resin pads are light, quiet, and well-suited to XC racing conditions.
• Anodised aluminium body: Lightweight and durable construction optimised for cross-country race weight targets.
• Straight-line hose connection: Clean hose routing reduces potential leak points and simplifies installation.
• Ice-Tech pad compatible: Works with Shimano Ice-Tech pads for enhanced heat dissipation in longer or more demanding rides.

XTR Race Technology

The BR-M9110 sits at the top of Shimano's MTB hierarchy, sharing the XTR M9100 series platform with the lever, rotor, and hose ecosystem. The flat mount interface keeps the calliper close to the frame and fork for a tidy, aero-friendly install. Ceramic pistons resist heat build-up better than alloy alternatives, ensuring consistent bite point throughout a race stage.

Compatibility & Fit

Flat mount interface — rear use only (front flat mount installation is not possible with this calliper). Compatible with 140mm and 160mm rotors; Shimano recommends the RT-MT900 rotor for best performance. Actuation via mineral oil hydraulics. Recommended brake lever: Shimano BL-M9100 (sold separately). Hose: SM-BH90-SS (sold separately). Part of the Shimano XTR M9100 groupset.
