How do crank arm bike power meters measure power? Are they more, less, or the same in accuracy to pedal power meters?
Crank arm bike power meters measure power by measuring the strain on the crank arm as you pedal. They do this by using strain gauges, which are small electrical devices that change resistance when they are bent. The strain gauges are attached to the crank arm, and when you pedal, the strain on the crank arm causes the strain gauges to bend. This change in resistance is then converted into a voltage, which is proportional to the power you are generating.
Pedal power meters measure power by measuring the force you apply to the pedals. They do this by using strain gauges that are attached to the pedals. When you pedal, the force you apply to the pedals causes the strain gauges to bend, which changes their resistance. This change in resistance is then converted into a voltage, which is proportional to the power you are generating.
So, which type of power meter is more accurate? The answer is that both types of power meters can be accurate, but crank arm power meters are generally considered to be more accurate than pedal power meters. This is because crank arm power meters measure the power that you are generating at the source, while pedal power meters measure the power that is being transferred to the pedals. This means that crank arm power meters are less likely to be affected by factors such as chain tension and pedal float, which can affect the accuracy of pedal power meters.
