The Shimano XTR FC-M9200 is the flagship cross-country crankset from Shimano's top-tier XTR M9200 groupset. Built for XC racers and performance trail riders who demand the ultimate in stiffness-to-weight, it pairs HOLLOWTECH II cold-hammer hollow-forged aluminium arms with an integrated 24mm steel spindle — eliminating flex at the arm-to-spindle interface for efficient, direct power transfer on every pedal stroke. Sold without chainring and bottom bracket so you can spec exactly what suits your riding.

Highlights

• HOLLOWTECH II hollow-forged arms: Cold-hammer forging creates a hollow structure that maximises stiffness while keeping weight to a minimum — the hallmark of Shimano's flagship cranksets.
• Integrated 24mm steel spindle: The spindle threads directly into the drive-side arm, removing any flex at the joint and improving power transfer.
• 55mm chainline for Boost: Optimised for 148mm Boost rear axle spacing, keeping the chain aligned and running smoothly across all 12 gears.
• DYNAMIC CHAIN ENGAGEMENT+: Direct-mount chainring interface is engineered to work with Shimano's HYPERGLIDE+ chain and cassette system for fast, precise shifts under load.
• Direct-mount chainring interface: Accepts SM-CRM96 chainrings (28T–38T, sold separately) — no spider, no extra weight.
• XC-optimised Q-factor: Narrow stance geometry keeps power transfer efficient and reduces lateral muscle fatigue on long race efforts.

XTR M9200 — Shimano's Pinnacle MTB Groupset

XTR M9200 represents the culmination of Shimano's mountain bike engineering. Every component in the groupset has been refined for XC racing and fast trail riding — lighter, stiffer, and more reliable than its predecessors. The FC-M9200 crankset carries that philosophy through to the foundation of your drivetrain.
