Shimano Dura-Ace FC-R9200-P Hollowtech II Power Meter Crank w/o Chainrings

The Dura-Ace FC-R9200-P Crank by Shimano - Power meter with high accuracy

Thanks to the Shimano FC-R9200-P crank, here in the version without chainrings, you can equip your Dura-Ace 2x12-speed road bike groupset with a power meter on both sides. This gives you access to information about your overall performance, cadence, torque efficiency, left-right balance and round pedalling. The accuracy of the total of 24 strain gauges is even higher than the previous model, with a deviation of only 1.5%. Thanks to Bluetooth and ANT+ radio protocol, there is broad compatibility with bike computers and similar devices.
The lithium-ion battery is located in control unit on the crank spider, which you can easily recharge yourself. If it is completely full again after about 2.5 hours, it will last for at least 300 hours. By the way, the charging cable is the same as for your Dura-Ace Di2 shifter. You can also carry out firmware updates via the E-Tube Project. On the housing of the control unit, you will find an LED that signals the battery charge level and a button for easy zero calibration. Of course, the entire construction is waterproof and there is active temperature compensation, so you don't have to worry about the weather. You can attach the magnet for cadence measurement to the chainstay, seat tube or down tube using the included positioning tool.
Apart from these special features, the FC-R9200-P is technically identical to the " normal" Dura-Ace crank. It converts your power into propulsion in a highly efficient manner, is characterised by an optimal stability/weight ratio thanks to the Hollowtech II design and inspires with precise, fast shifting processes. The crank arms are hollow-formed, which results in a significant weight saving. Except for the axle, all essential parts were made of lightweight metal. FC-R9200-P has an asymmetrical 4-arm bolt circle diameter of 110 mm. It produces a chainline of 44.5 mm and has a Q-factor of 148 mm.

Technology:

Hollowtech II
Shimano Hollowtech II is a crank bottom bracket system designed to achieve an ideal ratio of stiffness, weight and rotational efficiency. It is based on an integration of the bottom bracket and the right crank arm and works with a 24 mm axle or bearing diameter, which has proven to be optimal in terms of stability. In many cases, the bearing cups are on the outside so that the load is better distributed. High-quality precision seals ensure a long service life.

Second-Generation Power Meters
Shimano second-generation power meters use an improved force vector analysis and are therefore more accurate than their predecessors. Both crank arms have 12 sensors each, which are mounted in such a way that the crank deformation can be compensated for and the acting forces can be identified. The right and left sides are connected via the battery located in the axle, ensuring accurate measurement on both sides. The built-in temperature compensation contributes to the precision. You can easily recharge the battery with the Di2 charging cable EW-EC300. The power meters have Bluetooth and ANT+ compatibility to communicate with bike computers and smartphones. For firmware updates and data display, Shimano provides the E-Tube Project Cyclist App or the E-Tube Ride App. A more detailed performance analysis is possible via Shimano Connect Lab software.
