Power meters are very special devices made for collecting data during training and competing used by pro riders and other aspiring cyclists. This technology has been on the market for quite some time now, so professional athletes are very familiar with it. It is a complex and expensive piece of equipment if you are contemplating buying a power meter, you should think hard about what your expectations from the sport and your goals are, and decide accordingly.
Power meters are lightweight and small, but very precise units. Cyclists use them to measure the power exerted through the pedals, hence the name. They use strain gauges to measure the torque applied, which combined with angular velocity calculates the power.
This device can be paired wirelessly to transmit and display the gathered data on the cycling computer, your smartphone, or your smartwatch. Used this way, it gives a variety of information to the cyclist in real time. Simultaneously, it stores the same data for the user to access and analyze at their own discretion. Collected data gives a great base for a very accurate analysis of the current drive, so it makes them an excellent addition to training.
There are three basic types of power meters:
- Crank-based or spider is the mostly used type of power meter. In this case, the strain gauges are located in the crank arms or the spider of the chainring. This allows measurements separately for the left and right leg, under the presumption that both sides have installed strain gauges. Otherwise, more affordable systems measure the output of one side only which can lead to misleading conclusions. In general. This system is very accurate with a deviation of +/-1.5%.
- Pedal-based power meters are very popular just as well and even more accurate with a deviation of +/-1%. The strain gauges are installed on either or both pedals and the installation is simple. It is preferable to use it on both sides for the accuracy of the measurements and the possibility of early detection of any muscular imbalances.
- The rear wheel hub is the third option for installation of the power meter which gives back very accurate readings with +/- 1.5% deviation. They are can be easily installed, but their disadvantage is that they can only read total power output.
