The benefits of cycling with a power meter

Cycling with a power meter is steadily growing in popularity, largely because it has become more affordable and accessible.

While heart monitors are still perhaps more commonly used in cycling, there are some instances where cycling with a power meter will provide more accurate data.

If you’re an avid road cyclist, cycling with a power meter is a great way to track your progress over time. And because power meters are not affected by external factors such as whether you’ve had enough sleep or are dehydrated, it’s worth investing in one to get a more detailed look at your training progress.

What is a cycling power meter?

Power meters use strain gauges to measure the force being applied by the cyclist. They can measure the cyclist's power output in real time and aren’t affected by external factors.

Power meters give you a reading of how much energy you’re using in watts. This means you can track the amount of effort you’re applying as you train, as well as calculate your fitness level and the amount of calories burnt during a session.

Power meter vs heart monitor

The key difference between using a power meter and a heart monitor is that a power meter measures your power output, whereas a heart monitor measures your heart rate. Heart rate monitors usually come in two forms: those that you wear on your wrist and those that you wear on a chest strap.

A heart rate monitor can track when you’re hitting your target zones when you’re cycling in intervals. The caveat to this is that heart monitors usually lag behind slightly in tracking when you’re in that target zone, as your heart rate takes time to rise once you start pushing yourself to go faster. In contrast, power meters register the increased force you’re exerting immediately.

What are the different types of cycling power meters?

Pedal

As you may have guessed, a pedal-based power meter replaces the normal pedals you have on your bike. This makes them easy to install and use compared to some other power meters, and you can even get ones that track each leg individually.

Crank arm

Most crank arm-based power meters on the market replace only the left crank arm on your bike. Before you purchase one, make sure you check its compatibility with your current bike. If you haven’t bought one with the right fit, it can cause issues with hitting the bike frame while you cycle.

Spider

Cycling with a spider-based power meter can add a fair bit of weight to your bike, but they’re still one of the most popular choices among cyclists. These power meters replace your bike’s crank spider and can fit a wide range of bike types, making it possible to swap between multiple bikes if needed.

Spindle/Axle

A spindle-based power meter sits inside the axle of the crankset of your bike. As they’re quite small in comparison to other power meters out there, they don’t add much weight to your bike.

Why should I consider cycling with a power meter?

1. Achieve more accurate data

As we’ve already mentioned, using a power meter can give you more accurate data that isn’t affected by external factors. This makes them a really useful tool for measuring your improvement over time. Although heart rate monitors can be useful, they can be influenced by various other factors that will affect your heart rate.

For example, drinking coffee, not getting enough sleep, and being hydrated can all affect your heart rate reading. This is why if you want to use a heart rate monitor, it’s a good idea to use both devices in unison to get the most accurate readings of your progress.

2. Use your training time more efficiently

Most cyclists have a finite amount of time to train. When time is limited, a power meter can help you use your time more efficiently than just cycling aimlessly around a select route.

If you’re training in intervals, a power meter can give you the stats for the amount of effort you’re putting in in real time. With this information, you can keep better track of the amount of time you spend in each interval and level of intensity, making your training more efficient.

3. Learn your strengths and weaknesses

The data gathered by the power meter can help you clearly see your cycling technique's strengths and weaknesses.

For example, if you’ve recently recovered from an injury and are just getting back into training, some power meters can provide feedback on the amount of force applied by each foot separately so you can identify if the amount of pressure you’re applying is uneven.

4. Helps you to plan your races

Once you’ve learned how long for and at what force you can cycle at, you can better plan your intervals during races. This helps you to ensure you’re performing at your best during a competition using the data collected by the power meter during your training.

5. Share data with your coach

If you’re currently training for a race and have a coach you’re working with, you can easily share your training data with them even when you’re apart. This allows your coach to provide you with more accurate advice on improving your performance as they’ll be better informed in real time on how you’re improving.
