Best Overall Pedal

1. Favero Electronics Assioma DUO

This pedal power meter is one of the absolute best on the market in terms of both accuracy and price. It’s made in Italy, which produces some of the highest quality cycling equipment you can buy, and promises accuracy within 1%.

You can get these pedals in UNO, which features a power meter in just the left pedal, or DUO, which has power meters in both pedals.

The dual-sensor pedal package costs less than $1000, which is almost unheard of for such high-quality equipment.

This pedal power meter is ideal for cyclists of all levels. Everyone from beginners to professional athletes can use this one very easily. It screws into your bike just like any other pedal would, making it supremely easy to install.

This meter is equipped with cutting-edge technology, including an auto-calibration feature to make it easy to start off. It connects easily using both Bluetooth and ANT+.

It uses the company’s unique IAV Cycling Dynamics, which uses an integrated gyroscope to measure the true instantaneous angular velocity of every stroke. This is significant, as most power meters use an average.

But in addition to measuring this metric, you can also measure Power Phase, Rider Position (seated or standing), and Left/Right Balance.

They’re waterproof, dustproof, and rechargeable using a micro-USB cable. The included charger is magnetic, which prevents accidental damage by yanking or bumping.

Still not sure about the best power meters for triathletes? Here are some of the most common questions to help you decide if a power meter would be a worthwhile investment for you.

What Is a Bike Power Meter?

A power meter is a small electronic device that measures the rider’s power. In broad terms, this is the amount of effort the rider is putting into their ride.

The number displayed by the power meter is a direct representation of how hard you’re hitting those pedals!

Different Types Of Bike Power Meters

There are a few different types of power meters. They all do the same thing, but the deciding factor for you will most likely be convenience.


These are typically the most accurate as the chain on your bike is directly responsible for the movement of your bike. It’s also the first, original power meter design.

Replace your chainring and crankset, including cranks, with this device. It’s easy to replace your wheels or pedals without disrupting the device.

Although it’s pretty much the most accurate one there is, it also has some downfalls.

These kinds of power meters are not easy to transfer from bike to bike, as they become almost “built-in”. This also makes them a little tricky to install, so if you aren’t quite familiar with the process, it may be best to get it professionally installed.

Chainring-and-crankset power meters also tend to be a fair bit more expensive than the other types.

Crank Arm-Based

These are much easier to install and still tend to be quite accurate, as they are positioned close to the powertrain center of your bicycle.

A crank arm-based power meter takes the place of the crank arm (the piece that links the pedal to the chainring/crankset) on one side of your bike. It’s simple, unobtrusive, and unaffected by wheel changes.


These are basically pedals with a power meter built-in. You can get them for just one pedal or for both.

These are typically quite affordable and super easy to install. It’s as simple as putting a pedal on your bike, which even beginners can do with ease.

They’re also super easy to transfer from bike to bike. If you have more than one bike and you’d like to use your power meter with both/all of them, this is an ideal solution.


Power meters positioned in the spider of a crankset (the part the chainring bolts onto) have been around since the 80s! They were, for a long time, the gold standard of power meters for cyclists of all types.

The spider can be thought of as the heart of the bike. It’s an excellent place to get accurate measurements, as it measures both right and left leg power. They’re usually much more durable as well, thanks to being protected by the spider.

Smart Trainer-Based

This might not be useful for triathletes who want to measure their power while on the road. These power meters are built into smart trainers that you’d use while at home.

They’re ideal for athletes who want to train hard on a smart trainer, but quite limiting in terms of use in the outside world.

What Are The Advantages Of Power Meters?

Using a power meter correctly can help improve your performance. Interpreting your data can give you an indication of whether your fitness is good or needs to be worked on.

Understanding your power can be useful for pacing yourself correctly throughout races. It can also help you to know which training zones to train in for the best results, depending on your goals.
