The Shimano Dura-Ace FC-09 is the official replacement crankset developed for the 11-speed Dura-Ace and Ultegra global recall program — and it's far more than a stopgap. Shimano built the FC-09 on current R9200-generation Hollowtech II crank arms, re-spaced for 11-speed chainring compatibility, bringing next-generation stiffness and weight savings to 11-speed drivetrains. The 54-40T combination in 175mm suits powerful road racers and criterium riders who demand the tallest gearing available in a 2× setup, paired with a longer lever arm for maximum power output.

Highlights

• R9200-generation arms, 11-speed spaced: Shimano's latest Hollowtech II crank arm technology adapted specifically for 11-speed drivetrain compatibility.
• 54-40T chainring combination: Wide-range double setup ideal for fast road racing, criterium events, and powerful riders seeking tallest available gearing.
• 175mm crank arm length: Extended lever arm suited to riders with longer legs targeting maximum power transfer.
• 110mm asymmetric 4-bolt BCD: Lightweight spider design provides the stiffness of larger BCD rings while keeping weight low.
• Hollowtech II spindle interface: Industry-proven 24mm hardened steel spindle interface for stiff, precise power transfer.
• Purpose-designed 11-speed chainrings: Tooth profiles and shift ramps engineered specifically for 11-speed shifting dynamics.
• 2×11-speed compatibility: Works with Shimano Dura-Ace 9000, R9100 mechanical and Di2 groupsets.

Next-Generation Engineering for 11-Speed

The FC-09 brings the hollow-forged arm construction of Shimano's current 12-speed R9200 Dura-Ace groupset to 11-speed drivetrains. The asymmetric four-arm spider concentrates material where torsional rigidity matters most, allowing Shimano to shed grams without compromising the stiffness that Dura-Ace demands. The result is a crankset that outperforms the original FC-9000 and FC-R9100 it replaces — lighter, stiffer, and built to current production standards.

Precision Front Shifting

The FC-09's chainrings are purpose-engineered for 11-speed shifting dynamics. Carefully profiled teeth and machined shift ramps guide the chain cleanly between the 54T outer and 40T inner ring under all conditions — whether powering up a climb or launching a sprint. The 54-40T combination was introduced specifically with the FC-09 program, giving riders a wider-range double option not previously available in the 11-speed Dura-Ace range.

Compatibility & Fit

The FC-09 is designed for Shimano 11-speed road drivetrains, compatible with Dura-Ace 9000, R9100 (mechanical and Di2), and Ultegra 6800 and R8000 groupsets. The Hollowtech II interface requires a compatible English-threaded (68mm or 70mm) or press-fit bottom bracket with a 24mm spindle bore — such as the Shimano SM-BBR60 or SM-BB72-41B (not included). Compatible with Shimano 11-speed HG-X11 and HG-EV road chains. Confirm bottom bracket shell standard and chainline with your frame builder or bike shop before purchasing.
