how much effort you are putting into pedaling at any given moment. This makes it a
highly reliable metric for training, as it’s not affected by external conditions such as wind
or terrain.
How Power Meters Work
Power meters typically measure the force applied to the pedals, crank arms, or rear hub,
combined with the angular velocity (cadence). This data is then converted into watts,
giving you an instant and accurate reading of your power output. There are several types
of power meters including:
Crank-based power meters: Installed on the crank arms or spider, measuring the
1.
force directly where the pedaling happens.
Pedal-based power meters: Integrated into the pedals; easy to swap between
2.
bikes.
Hub-based power meters: Located in the rear hub, measuring the torque applied
3.
to the wheel.
Shoe-based power meters: Placed in the cycling shoes and measure power
4.
through foot pressure.
Each type has its pros and cons, but all provide reliable power data that can enhance your
training.
