Power Meter Guide
Power Meter Guide
Power meters are the best way to measure your performance on the bike as they take out variable like wind and surface conditions that can affect your ride times. There are many different types of power meter available, but they will be one of three main types.
Note: Power meters need cycling computers in order to record information. They are normally bought separately and work in conjunction to record and translate your data, using either Bluetooth or ANT+ to connect wirelessly. Most computers and power meters will use one or the other, with a few being compatible with both ANT+ and Bluetooth, so it’s worth making sure your computer matches up with your power meter.
Chainset Power Meters
Chainset power meters are perhaps the most accurate type available and are designed as a part of the crank arm or chainring.
Relatively easy to use, crank arm power meters have a sensor that is incorporated into the crank arm, making them fairly hidden and stealthy. Chainring meters have the sensor attached to the crank spider that holds the chain rings.
Both single sided crank arm and chainring power meters measure power from one side, this means that they don’t pick up on any differences between your legs. Double sided crank arm meters offer the most accurate readings. Chainring based power meters are not so easy to change between bikes, but crank arm power meters can easily be swapped between bikes, as long as the chainset is the same.
Pedal Power Meters
Pedal power meters make up part of the pedals so they can easily swapped between bikes. This means you can get accurate power readings whichever bike you choose to train on. This gives you a single solution to measuring your output on multiple bikes.
Pedal power meters show the smoothness of your pedalling as well as the accuracy of your pedalling position, as they are found on both pedals. Compared to other types they can be a bit more susceptible to knocks as they extend further outwards compared to other meters.
Wheel Hub Power Meters
Hub power meters provide a stealthy way to measure your power output and are easy enough to swap between bikes should both bikes be compatible between wheels. They can be a bit heavier than other power meters, but they are accurate and reliable, and don’t add any extra pieces to your bike.
