One of the best tools for getting extra data is a power meter. They are used by many cyclists, both racing professionals and recreational riders. In the past couple of decades, they have revolutionized cycling and are very common technology in turbo trainers.
In this article, we will be telling you all about power meters and what we classed as the best power meter for road bikes from the Rotor range. We will be discussing:

- The Benefits Of A Power Meter

What Is A Power Meter?

A power meter is a component fitted with a small device called a strain gauge. They come in all shapes and sizes, but the most common being built into a crank arm. They typically don’t come standard on bikes but are one of the best upgrades you can make. 

A power meter can sense the amount of pressure being applied to the pedals alongside the cadence. Using all this data can give you a power reading in watts. The scientific calculation is Torque x RPM = Power.

The Benefits Of A Power Meter

Power meters come with many benefits, and although they are not the cheapest upgrade, they offer some excellent advantages that are important to understand.

Real-Time Feedback

While cycling, you get real-time feedback on how hard you are working. This can help you pace properly and tell you when you're not working hard enough or pushing too much. 

Training Tool

Power meters are an excellent tool for training. Instead of having to work out training zones using rough heart rate data, you can accurately apply the correct load because you know how hard you're working at all times.

Data And Assessment 

A power meter gives you a lot of data to work with. Not just telling you what power you're producing but also how quickly you fatigue, how long you might need to recover, and the improvements you are making over time. 

Racing Strategy

Having a power meter is excellent when racing. When you are caught up in all the adrenaline of racing, it can tell you when you want to stay with the pack and conserve and when to make the break. This data is vital for knowing when to make the sprint.
