Shimano's flagship road power meter is built straight into the crank, so the Dura-Ace FC-R9200-P measures the effort from each leg independently and lets you train with the precision the professionals rely on. Dual-sided readings accurate to within 1.5 per cent and a rechargeable battery rated for hundreds of hours turn every ride into reliable, actionable data — with no separate pods or sensors to bolt on.

Highlights

• True dual-sided power: independent left and right measurement delivers genuine leg-balance data, not a doubled estimate from one side.
• ±1.5% accuracy: strain gauges bonded into both crank arms maintain class-leading precision across the full calibration range.
• 300+ hour battery life: integrated, fully waterproof rechargeable Li-ion battery charges in around 2.5 hours and lasts weeks of regular riding.
• ANT+ and Bluetooth LE: connects simultaneously to head units, smartphones, and training apps with no pairing hassle.
• Hollowtech II construction: the same lightweight, stiff aluminium crank arms used on the standard Dura-Ace crankset — power measurement adds no compromise in feel or efficiency.
• Active temperature compensation: readings stay consistent as conditions change, no matter what the weather throws at you.

Power you can trust

Strain gauges bonded into both crank arms capture the load from each pedal stroke separately, giving you genuine left/right balance that competitors billing from a single sensor simply can't match. A simple zero-offset calibration before you roll out keeps the numbers honest ride after ride, and Shimano Connect Lab lets you dig deeper into the data when you're off the bike.

Built to last in all conditions

The rechargeable Li-ion battery is fully sealed and waterproof, rated for more than 300 hours of ride time per charge — weeks of riding before you need to think about plugging in. A full charge takes roughly 2.5 hours via the supplied charging cable.

Dura-Ace performance at every watt

The Hollowtech II crank arms are the same race-proven hardware found on the standard Dura-Ace FC-R9200, so integrating power measurement costs you nothing in stiffness, shifting quality, or weight at the pedals. Shimano's precision chainring geometry ensures crisp, reliable 12-speed chain engagement throughout the 50-34T compact range.
