Shimano Dura-Ace Power Meter Power Measurement Technology:
The newly developed power-measuring crank from the Dura Ace series with power measurement on both sides. The power meter’s central unit is compactly housed behind the crank spindle, and the strain gauges are integrated into the right and left crank arms. Thanks to the battery integrated into the axle, the Bluetooth interface and the ability to update the power meter’s firmware via the E-Tube platform. The Bluetooth® LE and ANT+ interfaces are compatible with many cycle computers. The power meter features a small magnetic adapter for charging the battery. This makes the system completely waterproof and visually elegant. Perhaps most importantly, however, are the battery life, the ease of charging, and the ANT+ and Bluetooth® LE connectivity, which make recording and utilising training data easier than ever before. Shimano power metre cranksets contain a total of 24 sensors – 12 per side – in a full-bridge configuration.
To accurately separate the force applied to the cranks in the tangential and normal directions, each sensor is positioned at an angle to compensate for crank deformation. This uniquely designed sensor increases measurement accuracy and enables the measurement of force vectors.
Thanks to active temperature compensation, Shimano-developed strain gauges, power measurement on both sides and an accuracy of ±1.5 per cent, the power meter reliably and quickly transmits data to ANT+/Bluetooth® LE display devices. Although many commercially available power meters use separate left-right measurement, Shimano power meter cranks feature a combined left-right configuration. The spindle connecting the left and right crank arms houses a lithium-ion battery that supplies power to the left and right sensors. The shared wiring of the left and right sensors eliminates even the slightest measurement time deviations and enables precise power measurement on both sides.
Shimano Power Vector Analysis
When used with Shimano Connect LAB, Shimano powermeters can analyse pedalling efficiency whilst riding or on your home PC. This requires Shimano’s E-Tube Ride app. Unfortunately, it is not compatible with Garmin devices.
When developing power metre cranks, SHIMANO engineers take into account the crank design, the manufacturing process, the materials used, and the crank deflection under load. And it is precisely this expert knowledge that enables Shimano to achieve such high-precision power vector measurement. Thanks to the latest technology and Shimano’s industry-leading expertise, the latest SHIMANO power metre cranks are cutting-edge training tools. The Dura-Ace power metre cranksets feature a total of 24 sensors – 12 on each side – in a full-bridge configuration. To accurately separate the force applied to the cranks in the tangential and normal directions, each sensor is positioned at an angle to compensate for crank deflection. This uniquely designed sensor enhances measurement accuracy and enables the measurement of force vectors. While power is important, a raw power figure alone does not give you the full picture. If you understand how you generate power and find ways to improve your efficiency, you can take your performance to a new level. Shimano’s power vector function provides real-time feedback on your pedalling, giving you a better understanding of your pedalling effort.
Shimano Dura-Ace R9200 Cranksets
Hollow-forged chainrings, thin-walled hollow-forged crankset arms and a reduced outer surface area bring the weight of the new Shimano Dura Ace FC R9200 crankset down to 609 grams. The design of the 2x12-speed Hollowtech II crankset not only boasts a look and aesthetic with cult potential, but also ensures enhanced performance. A wider, yet lighter than its predecessor, crank arm and the large chainrings featuring Hollowglide technology increase stiffness and optimise power transfer to the pedal.
Compatible bottom bracket shells – bottom brackets
There is now a wide variety of bottom bracket shells available on modern frames. Shimano offers compatible bottom brackets for only a few of these. The Wheels Outboard bottom brackets are significantly more durable than standard press-fit bottom brackets, as the cups are bolted together and thus sit flat and securely in the frame. Wheels bottom brackets are available with different bearing grades: ABEC3 standard bearings, angular contact bearings and ceramic bearings.
