Left crank potentiometer for Ultegra 8000.
If you want to reach the next level in your training or if you simply look for a better way to measure energy expenditure, a power meter is your best bet. The Power Cranks Ultegra Upgrade Kit is what you are looking for. With lightweight power sensors on a Shimano Ultegra bottom bracket, it offers the perfect way to integrate the power meter into the game.
Until now, the power meters have worked by means of two different methods: measuring the force produced by applying a static and linear load to a bottom bracket or plate, and using a power generation motor to give pedals on the bike. But cycling is neither aesthetic nor linear, and humans apply power very differently to a machine. That is why none of these methods responds to the problem of precision in the "real world".
And to make the best precision test, in all kinds of use scenarios, Specialized develops. its own cycling belt, the WinMill, which allows you to measure the power in a real way. This new indicator allows us to evaluate the accuracy in any condition: sitting in front of standing, different levels of power and cadence, different weights and a lack of models. This data acquisition process is our gold standard to check the power meters. In addition, through external validation and testing by the Locomotion laboratory in Boulder, Colorado, Power Cranks has been shown to present the highest accuracy in real-world scenarios (+/- 1.5 %).
Likewise. Power Cranks offers easy use, first level temperature compensation firmware and water resistant housing. Calibration is only necessary during seasonal fluctuations of temperature and the included key makes changing the battery a breeze.
