    How accurate is a power meter?

    Most brands claim accuracy between +/- 1% for crank-based power meters, and the tolerance can go out as much as 2-3% for less expensive options. Asking how accurate you need it to be, though, is a bit of a trick question, because the real answer is “it doesn't matter” as long as you stick with the same one.

    How does a spider based power meter work?

    Spider-based power meters use Magic Zero technology to automatically calibrate the power meter for you, so you never need to worry about calibration! MagicZero works by continuously monitoring the torque signals from the strain gages as you ride, so you can focus on the road ahead.

    Should you use a power meter for indoor riding?

    If you have a smart trainer for indoor riding, capture power data straight from your power meter rather than your trainer to keep your data consistent from outside to inside. If you have a standard indoor trainer, your power meter will make it “smart” by allowing you to capture power and cadence data and transmit it to your bike computer.
