Favero Assioma UNO Power Meter Pedals - Single-Side

Favero Assioma UNO Single-Sided Road Power Meter Pedals

The Favero Assioma UNO is a single-sided road power meter pedal system for riders who want reliable power data without going straight to a full dual-sided setup.

It measures power from the left pedal and estimates your total power output, giving you the key numbers you need for structured training, pacing, indoor sessions and tracking progress over time.

If you’re getting started with power-based training, or you want a simple pedal-based power meter you can move between road bikes, the Assioma UNO is a very tidy place to start.

"Super simple to set up and calibrate. Pedals hang nicely, super easy to clip into. 10/10 would recommend."

Why we like them

The Assioma UNO keeps things simple: install the pedals, pair them to your bike computer or training app, and ride.

Because the power meter is built into the pedal, you don’t need to change your crankset, bottom bracket or drivetrain setup. That also makes it handy if you have more than one compatible road bike and want to swap your power meter between them.

It’s rechargeable, accurate, easy to live with, and gives you the useful stuff — power, cadence and pedalling data — without making the whole thing feel like a spreadsheet with cleats attached.

UNO or DUO?

Choose the Assioma UNO if you want reliable single-sided power data at a lower price.

Choose the Assioma DUO if you want true dual-sided measurement, left/right balance, and more complete data from both legs.

Trev’s take

The UNO is the sensible option if you want to start training with power but don’t need full dual-sided data. You still get proper power and cadence numbers, easy setup, rechargeable batteries and the convenience of a pedal-based system. Good gear, without making your wallet cry quite as much as the dual-sided version.
