The Shimano Dura-Ace FC-9000 is Shimano's flagship 11-speed road crankset, built for riders who demand the absolute best in power transfer and front-shift precision. HOLLOWTECH II hollow crank arm construction delivers an outstanding strength-to-weight ratio, while the HOLLOWGLIDE outer chainring accelerates chain engagement for fast, reliable front shifts — even under load. The 52/36T semi-compact configuration suits road racing, gran fondo, and fast recreational riding.

Highlights

• HOLLOWTECH II construction: hollow crank arms maximise stiffness while minimising weight, a hallmark of Shimano's top-tier road components.
• HOLLOWGLIDE chainring: specially profiled outer chainring teeth accelerate chain pick-up for crisp, reliable front shifts under power.
• 4-arm asymmetric spider: places material precisely where pedalling forces are highest, achieving exceptional stiffness while reducing weight compared to the previous generation.
• 52/36T semi-compact gearing: versatile chainring combination suited to road racing, fast touring, and gran fondo riding.
• 110mm BCD: supports a wide range of Shimano-compatible chainring size options for future flexibility.
• 11-speed compatibility: engineered specifically for Shimano 11-speed road drivetrains including Dura-Ace 9000 mechanical and Di2 electronic groupsets.
• 24mm HOLLOWTECH II spindle: industry-standard interface for straightforward installation and broad bottom bracket compatibility.

Engineering Detail

The FC-9000 introduced Shimano's four-arm asymmetric spider design to the Dura-Ace line, positioning material where pedal forces are highest across the drivetrain stroke. The result is a crankset that matches the stiffness of the previous FC-7900 generation while weighing significantly less. The polished finish and refined arm profiles reflect the premium quality expected of Dura-Ace. Crank arm length of 175mm suits taller riders and those who prefer extended lever arm for climbing or time trialling.

Compatibility & Fit
