Accurate, Waterproof, and Dual-Sided
Serious cyclists demand precision, and the DURA-ACE FC-R9200-P power meter delivers just that. With dual-sided power measurement and a waterproof design, it's your trusty companion in all weather conditions. Its accuracy, with less than 1.5% strain gage error, ensures you get reliable data throughout your ride.

User-Friendly and Long-Lasting
No need to worry about battery life - the FC-R9200-P offers up to 300+ hours of ride time on a single charge. Thanks to its rechargeable Li-ion battery, you can keep your focus on the road. BluetoothLE and ANT+ connectivity make setup a breeze, making it a must-have for data-driven cyclists.

Unified Left-Right Design for Accurate Measurement
Unlike many power meters with separate left-right configurations, SHIMANO's FC-R9200-P boasts a unified design. The lithium-ion battery within the spindle connects both cranks, ensuring accurate power measurement on both sides. Say goodbye to minor deviations in measurement time.

Hollowtech II Technology
Designed around the well-respected Hollowtech II technology with uniquely developed chainrings featuring Hollowglide construction, this power meter crankset ensures fast precise shifting whilst still maintaining the strength which results in better power transfer. This component is finished off with a rechargeable Li-ion battery, Bluetooth LE and ANT+ connectivity, allowing this crankset to collect real-time precise and reliable power output data so you can track and analyse every detail of your ride to fine tune your training.
