Will a power meter make me faster?

The power meter itself doesn’t make you faster; you make you faster. Power meters simply give insight into both training and performance data that can guide your efforts and unlock your faster. The first step to deciding if a power meter is right for you is to determine what type of a rider you are.

Can smart meters give wrong readings?

Smart meters should mean more accurate bills because they should send readings directly to your supplier – meaning no more estimated bills. But they are still machines and inevitably can – and may very well – go wrong. Only time will tell if they will be more accurate at providing meter readings.

Heart rate and RPE can be useful for cyclists, but power is the ultimate training tool. It’s always possible to train without a power meter. Many riders still do. But anyone seeking serious improvement in their performance will benefit from using a power meter for structured training and data-driven riding.

What should stages calibration number be?

The expected range of values is within +/- 50 from 890, so expect to see numbers in the high 800s or low 900s when calibrating properly.

Should I ride with a power meter?

Power meters are especially useful for performing intervals, particularly short ones.
