Dura Ace R9200 – Never Compromise The Science of Speed. Speed was the mainspring in the development of this 12-speed road bike series of a new generation. Several years of research produced those innovations that make the Shimano Dura Ace R9200 even faster. Every component has been revised, refined and optimised to enable the decisive seconds of advantage – whether as a breakaway from the peloton or in the finish sprint on the Champs-Élysées. The electronic Di2 parts rely on Wireless technology where it matters to make shifting even faster and more reliable. Smooth shifting is also the aim of the Hyperglide+ system, already known from the MTB segment, which is designed to bring out maximum performance and the full potential of every racer. Shimano Dura Ace FC-R9200-P Powermeter crank The Shimano Dura Ace FC-R9200-P crank is designed for the 2×12-speed drivetrain system and performs two crucial tasks: It converts pedal power into propulsion and ensures extremely fast and precise shifting. Also the lightweight crank arms, manufactured using Hollowtech II technology, contribute to this. In addition, the integrated Powermeter also standards in terms of performance measurement with an optimised accuracy of ±1.5 %. It measures the cadence data and the resulting values on both sides, that means independently for the left and right leg. Thanks to its design, the data collection is also free from external influences such as incline, road surface or wind. Powermeter specifications: accuracy: ±1,5 % force measurement: left + right, 24 strain sensors cadence measurement: via magnet connectivity: Bluetooth / ANT+ ports: 1x EW-EC300 battery type: Li-Ion battery life: approx. 300 hours
