Shimano FC-R9200 Dura-Ace 12-Speed Double Power Meter Chainset - 172.5mm52/36T

Shimano s FC-R9200 Dura-Ace 12-Speed Double Power Meter Chainset delivers unmatched accuracy and efficiency for performance-driven riders. Built through years of development with pro teams, this chainset combines a fully integrated dual-sided power meter, HollowTech II technology, and advanced materials for exceptional precision, rigidity, and low weight. Its standout feature Shimano s first fully integrated power meter ensures stable, real-time data accuracy for consistent performance analysis in every ride.Key Features and Benefits: Fully integrated dual-sided power meter: Strain gauges built into both crank arms measure left and right power independently. This dual-sided setup ensures balanced data for more precise performance tracking and improved training accuracy. ±2% strain gauge accuracy: Factory-calibrated sensors maintain power readings within two percent of true output. This high precision helps riders make informed adjustments to pacing and effort for better race results. Bluetooth and ANT+ connectivity: Wireless communication allows data transmission to head units and easy firmware updates. This seamless integration keeps performance metrics current without manual setup. Rechargeable waterproof battery system: The built-in lithium-ion battery provides long runtime with complete weatherproof protection. This ensures reliable operation in any conditions, reducing maintenance and downtime. HollowTech II forged crank arms: Cold-forged hollow arms boost stiffness while reducing weight. The result is improved pedalling efficiency and power transfer for sharper acceleration and smoother cadence. Hollow outer chainring design: By removing flex from the outer ring, shifts remain precise even under load. This consistency under pressure enhances drivetrain reliability during racing or intense climbs. Optimised 12-speed chainring teeth profile: Designed specifically for Shimano s 12-speed chains, the teeth improve chain engagement. This reduces friction and energy loss, delivering smoother, more efficient power transfer. Improved structural rigidity: Enhanced crankset stiffness minimises flex during heavy loads. This stability maintains drivetrain alignment and ensures consistent gear changes across the full power range. Lightweight design evolution: The refined structure and hollow architecture cut weight without compromising strength. Reduced mass means quicker acceleration and more responsive handling. Wide range of ratios and lengths: Available in multiple configurations to suit rider preference and terrain. This flexibility ensures optimal gearing and fit for road, time trial, or triathlon disciplines.This power meter chainset is built for riders who demand precision in every detail. Its integrated dual-sided measurement, advanced HollowTech II structure, and 12-speed chainring interface deliver consistent accuracy and efficiency from training to competition. Every component works to maximise output while maintaining lightweight control, giving athletes a measurable advantage in performance analysis and drivetrain response.Engineered for elite performance and proven in pro racing, the FC-R9200 Dura-Ace Power Meter Chainset combines data precision, durability, and lightweight stiffness. It s the perfect choice for riders who value consistent accuracy and efficient power transfer in every pedal stroke.
