Shimano XTR Enduro M9220 12sp Cranks

The Shimano XTR FC-M9220 12-speed Enduro Crankset is built to withstand the most brutal demands of enduro racing and aggressive trail riding. As the strongest XTR crankset ever produced, it blends Shimano's legendary HOLLOWTECH II technology with specific design enhancements to deliver unparalleled durability, stiffness, and power transfer for riders who push the limits.

• Enduro-Specific Spindle: The FC-M9220 features a notably **thicker steel spindle** compared to its XC counterparts (like the FC-M9100). This robust spindle significantly boosts durability and survivability against heavy impacts and repeated stresses encountered in enduro racing.
• HOLLOWTECH II Construction: Utilizes Shimano's renowned hollow forging technology for the crank arms. This process creates exceptionally stiff and lightweight crank arms that maximize power transfer while keeping overall weight to a minimum.
• Optimized Q-Factor and Chainline: Engineered with a **176mm Q-factor** and a **55mm chainline**. This wider configuration is optimized for frames with wider rear hub spacing (like 148mm Boost), providing ample tire clearance, improved chainline for wider cassettes, and a familiar feel for enduro-focused riders.
• Direct Mount Chainring System: Incorporates a direct mount interface for Shimano's 1x 12-speed chainrings (like the SM-CRM96 or SM-CRM95). This system offers simplified chainring changes, reduced weight, and enhanced stiffness.
• Compatible with Dynamic Chain Engagement+ (DCE+) Chainrings: Designed to work seamlessly with Shimano's DCE+ chainrings, ensuring superior chain retention over rough terrain and promoting smoother, quieter pedaling.
• Durable Crank Arm Finish: The anodized aluminum crank arms provide excellent resistance to wear, scratches, and corrosion, maintaining the premium XTR aesthetic through harsh conditions.
• Versatile Crank Arm Lengths: Available in a range of lengths, typically from 160mm to 175mm (e.g., 160mm, 165mm, 170mm, 175mm), allowing riders to choose the optimal length for their body dimensions and riding style.
• Broad Bottom Bracket Compatibility: Features a standard 24mm spindle (HOLLOWTECH II) for compatibility with a wide range of Shimano threaded (SM-BB93) and Press-Fit (SM-BB94-41A) bottom brackets (sold separately).
• Single Ring Focus: Primarily designed for 1x12-speed setups, offering optimal performance with a single chainring configuration, ideal for enduro racing's emphasis on simplicity and wide gear range provided by modern cassettes.
