Train and race with data you can trust. The Shimano Dura-Ace FC-R9200-P is a fully integrated, dual-sided power meter crankset built into the top tier of Shimano's road groupset. Measuring force from both crank arms with ±1.5% accuracy, it gives you complete left/right power balance, cadence, and Force Vector data — all via a rechargeable battery that lasts 300+ hours.

Highlights

• Dual-sided power measurement: independent left and right output with ±1.5% accuracy across the entire calibration range.
• Force Vector technology: measures pedalling force direction and magnitude at 12 points per revolution (every 30°) on each crank arm to help refine technique.
• Fully integrated, waterproof design: no bolt-on pods or external modules — the power meter is built directly into the crank arms for clean, reliable all-weather performance.
• Rechargeable lithium-ion battery: 300+ hours of ride time; recharges in approximately 2.5 hours — no coin cell replacements.
• ANT+ and Bluetooth LE: pair simultaneously to a GPS head unit and a smartphone app for live data logging and coaching.
• HOLLOWTECH II crank arms: hollow aluminium construction bonded with a 24 mm hollow spindle for exceptional stiffness-to-weight ratio.
• Asymmetric 4-bolt 110 mm BCD: accepts Dura-Ace HOLLOWGLIDE chainrings engineered for 12-speed shifting precision.
• 165 mm crank arm with 52/36T chainrings: suits shorter-limbed or fit-optimised riders seeking a versatile road gearing range.

Power Measurement & Technology

Shimano's strain-gauge-based power measurement is built directly into the crank arms — 24 strain gauges in total — keeping the system clean and precise. The dual-sided setup captures independent left and right power output, providing the balance data needed to identify and correct pedalling inefficiencies. Force Vector goes further, logging the direction and magnitude of your pedalling force through the entire crank rotation so you can analyse and refine technique as well as track fitness. Data is captured at 12 points per revolution on each side, giving a detailed picture of where power is applied and where it is lost.

HOLLOWTECH II Construction

The FC-R9200-P uses Shimano's proven HOLLOWTECH II design: hollow aluminium crank arms bonded with a 24 mm hollow spindle that passes through an outboard bottom bracket. The outboard bearing placement widens the stance for improved stiffness and pedalling stability, while the hollow construction minimises weight without sacrificing rigidity. The 52/36T HOLLOWGLIDE chainrings are engineered specifically for 12-speed Dura-Ace shifting precision, and the large chainring incorporates carbon elements for further weight reduction.

Battery & Connectivity

The integrated rechargeable lithium-ion battery is housed in the crank spider and eliminates the need for coin cells. It delivers more than 300 hours of power per charge and refills in around 2.5 hours. Dual-protocol wireless — ANT+ and Bluetooth LE simultaneously — means you can pair to a GPS head unit and a smartphone app at the same time, making data logging and live coaching straightforward on race day or in training.

Compatibility & Fit

Designed for Shimano Dura-Ace R9200 2×12-speed drivetrains. Compatible with a 24 mm HOLLOWTECH II bottom bracket — Shimano BB-R9100 (threaded) or SM-BB92-41B (press-fit). Q-factor is 148 mm; chainline is 44.5 mm. This listing is for the 165 mm crank arm length with 52/36T chainrings. Minimum 10 mm clearance required between the left crank arm and chainstay. Not compatible with 11-speed drivetrains or double-tap shifting systems.
