The Evolution of Shimano's New Dura-Ace Power Meter

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Power is more than a number.
Add meaning to your training with
Shimano's Force Vector analysis.

While power is important, a simple output number doesn't give you the full picture. Understanding how you develop power and finding ways
to improve efficiency can unlock new levels of performance.

SHIMANO's Force Vector feature gives you real-time feedback on your pedal stroke, providing a more complete picture of your effort.

Arrows indicate the direction and amount of force you're applying to the pedals. Blue arrows show force rotating your cranks forward while red arrows represent force opposing transmission to the rear wheel.

Force Vector is made possible by SHIMANO's expertise in designing and manufacturing cranks

When designing power meters, SHIMANO engineers consider crank structure, the manufacturing process, materials used, and how a crank flexes under load. It's this expertise that allows SHIMANO to achieve such accurate Force Vector measurement.

Using the latest technology and SHIMANO's industry-leading knowledge, the latest SHIMANO power meters are powerful training tools.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Optimal sensor placement

SHIMANO power meters contain 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 direction and normal direction, each sensor is positioned at an angle to compensate for crank deformation. This uniquely-designed sensor increases the precision of measurement and enables Force Vector measurement.

*Full bridge configuration: A sensor circuit configuration that improves temperature compensation with large sensor output.

 

 

 

 

 

 

 

 

 

 

Unified left-right design

Although many power meters over the world have a separate left-right configuration, SHIMANO power meters have a unified left-right configuration.
A lithium-ion battery is incorporated inside the spindle that connects the left and right cranks, and provides power to the left and right sensors.
Wiring the left and right sensors together eliminates minor deviations in measurement time and enables accurate measurement of power on both sides.

Long-life battery

Power meters that have a lot of sensors and send a large amount of data have high power consumption. However, SHIMANO power meters achieve low power consumption thanks to a unique circuit configuration. A rechargeable lithium-ion battery enables long-term use while contributing to precision. The EW-EC300 Di2 charging connector is used for charging, making bicycle battery management easier.
