If you want to up your cycling game, a power meter is the gold standard to measure your performance and the effectiveness of your training. Coupled with heart rate measurement, you’ll be able to assess how your cycling efficiency and ability to sustain effort is changing over time.
Having info on the power you’re putting out will also allow you to gauge your effort as you ride to ensure that you are working as efficiently as possible. Most power meters are compatible with both ANT+ and Bluetooth computers, so you can record your power on your head unit. You can then analyse your data post-ride, either with your preferred app or any analysis package that comes with the power meter hardware.
We’ve scoured the web for the best power meter deals this Black Friday so you don’t have to.
