FAVERO Assioma UNO Power Meter Pedals review

Have you ever wondered whether a precise, simple change to one small part of your bike could alter the way you feel every mile you ride?

FAVERO Assioma UNO Upgraded Single-Sided Power Meter Pedals | Waterproof | Bluetooth and ANT+ Connectivity | Bundled with 1 Pair of Black Cleats, 1 Pair of Red Cleats and Cleaning Cloth — First impressions

You open the box and the pedals sit there, steady and matter-of-fact, as if they have been waiting for exactly this moment. They look familiar — like pedals should — but the idea that they contain a nervous system of sensors makes them feel a little more guarded, polite almost, as if they will tell you things you did not know you were doing.

You notice the weight right away: heavier than some lightweight racing pedals but not clumsy. The finish is modest and functional, not showy, which matches the accessory in the box — two sets of cleats and a small cleaning cloth. The Favero name carries a reputation; you can feel, immediately, that the product is positioned for someone who cares about measurable progress without drama.

Unboxing and what’s in the box

You unpack carefully, as though each piece has a small responsibility to fulfill. Everything is arranged with the quiet efficiency of someone who knows cyclists and their patience.

There are three main surprises: the single-sided nature of the power meter, the inclusion of both six-degree and zero-degree cleats, and the small cleaning cloth tucked into the corner. Each item feels intentional, not just an afterthought.

In the box — detailed breakdown

You like lists because they orient the mind. Here, the items are listed plainly so you know what to expect and what to keep safe.

You will appreciate that the box contains both cleat options. You can choose between a more forgiving float and a locked-in interface without running to the bike shop. The inclusion of a cleaning cloth is small but considerate; when you live with metal and sweat and road grit, even small gestures like that are useful.

Design and build quality

You hear people talk about stainless steel bodies and lightweight composites as if those phrases were ingredients in a promise. With the Assioma UNO, the design speaks of utility first: robust materials, a finished surface that is resistant to abrasions, and electrical contacts protected by magnetic covers.

You can tell the pedals have been designed to be moved between bikes. The thread and body feel like the pedals will not complain when you swap them from a training bike to your weekend ride. They are not featherlight, but they give you the impression of being built to last, with an emphasis on reliability rather than the race-obsessed pursuit of grams.

Waterproofing and durability

You ride in a city that remembers rain. The idea that your power meter pedals claim waterproofing offers immediate relief. The seals are tight where they need to be, and the magnetic charging ports feel protected without being finicky.

You should still avoid long immersions and hosing them down with reckless abandon, but for most commutes, winter washes, and rainy training sessions, the unit’s build inspires confidence. The threaded spindle, the body, and the pedal platform all hold up to expectations for a product meant to be used, not displayed.

Installation and bike swapping

You will understand the appeal quickly: installing the Assioma UNO is almost exactly the same as threaded pedals you’ve used for years. You don’t need a torque wrench or special adapter to get them started. That ease is no small thing when you want to move them between bikes without a long ritual.

Screwing the pedals into the crankarm is familiar work. The left-side sensor is unobtrusive. The first time you set them up, you’ll probably check the cleat alignment twice; after that, it becomes part of your pre-ride routine. They thread in cleanly, and the recommended torque range is modest and achievable with basic tools.

Fast to move between bikes

You will find that the Assioma UNO is designed for the rider who owns more than one bicycle or for a coach who needs to move sensors between clients. There’s a kind of liberty in that: you can take a single power meter and let it be the common language across bikes.

The pedals sit in the crank as naturally as any other. You can change bikes in minutes, and because they act like normal pedals, there’s no need to recalibrate your pedals or hunt for adapters each time. They are as mobile as you are, ready to tell their story wherever you ride.

True Left Power Data — what it means for you

You need to understand what “true left power” implies in practical terms. The Assioma UNO measures power from the left pedal and extrapolates total power from that measurement. For many riders, that gives you reliable data at a more accessible price point.

You should know that single-sided power meters work well for a lot of training purposes. If your pedaling balance is consistent, you’ll get numbers that allow you to pace intervals and judge improvements. If you are dealing with a significant imbalance between legs, you may want to consider whether a dual-sided system is necessary for your goals.

How single-sided measurement affects training

You will still be able to do structured workouts, threshold tests, and power-based races with the Assioma UNO. The output integrates with head units and apps via Bluetooth and ANT+, and you’ll see cadence and power numbers that align with standard training plans.

You should pay attention to the left/right balance metric (more on that below) because it lets you understand whether the single-sided extrapolation is reasonable for you. If your balance remains stable over weeks of training, your session-to-session comparisons will be meaningful.

Pedaling analytics: what you’ll actually get

You expect power and cadence, but you’ll get more. Because the sensor sits where your foot applies force, the Assioma UNO provides insight into how that force is delivered. You’ll see left/right balance, torque efficiency, and pedal smoothness, metrics that go beyond raw watts.

These metrics aren’t simply numbers on a screen; they are the record of your interaction with the bike. They tell you whether your foot is working in a steady circle or if there are spikes of power that suggest timing issues. Watching these numbers after a focused drill can feel like reading a map of your body’s movement.

Left/Right balance

You will notice that left/right balance is a quiet teacher. If one leg habitually does more work, the balance number will reveal it. Seeing that imbalance can prompt adjustments — whether that’s strength work in the gym, targeted intervals, or paying attention to stroke mechanics.

You should not panic at a small imbalance; many riders have asymmetries. What matters is consistency and whether your interventions produce gradual changes. Balance is a diagnostic, not a verdict.

Torque efficiency and pedal smoothness

You will be given metrics that describe how effective your pedal stroke is. Torque efficiency measures how much of your applied force contributes to forward motion, and pedal smoothness quantifies the uniformity of that force across the stroke.

You can use these numbers to make tangible improvements. Try a set of single-leg drills or cadence work, then watch the metrics. The change may be subtle, but the data will show whether you are moving toward a more efficient stroke.

Connectivity and compatibility

You want the data to go where you already look for it. The Assioma UNO supports both Bluetooth and ANT+, which means it plays well with modern head units, phones, and most cycling software. The pairing process is straightforward and familiar to anyone who’s paired a heart rate monitor or a smart trainer.

You should check firmware updates occasionally; Favero has pushed updates in the past that refine stability and correctness. When you pair the pedals, you’ll see them as a power source and a cadence source — simple and direct.

Which devices and apps work best

You will find the Assioma UNO compatible with popular devices: Garmin, Wahoo, Zwift, TrainerRoad, and several others. Integration is smooth, and you can stream power to a smart trainer or analyze rides afterward in your preferred software.

You should verify the specific head unit model for full compatibility, but for most modern devices using ANT+ or Bluetooth Smart, the pedals will be recognized without drama. The dual-protocol support means you can broadcast to two devices simultaneously if needed.

Battery life and charging

You want something reliable, not something that forces you to rearrange your life around ports and cables. The Assioma UNO offers rechargeable batteries with approximately 50 hours of runtime per charge, which is generous for most training cycles and weekend adventures.

You will appreciate the magnetic charging connectors: they are tidy, they snap on easily, and they give you exactly the kind of low-friction interaction that good design provides. The unit goes into automatic standby when inactive and turns on as soon as you start pedaling, making power management feel invisible.

Practical charging tips

You should charge the pedals after long training blocks or before a multi-day event. The magnetic connectors are durable, but they still benefit from being kept clean, which is where the included cleaning cloth becomes useful.

You will want to keep an eye on battery percentage if you’re doing a long ride or an event. Charging between sessions is easy and fast enough that battery anxiety tends to evaporate quickly. For most riders, a weekly top-up is sufficient.

Cleats, float, and fit

You own your feet; cleats are the interface between you and the machine. The Assioma UNO package contains both red six-degree float cleats and black zero-degree cleats, letting you choose the mechanical relationship that suits your body.

You should experiment. If you come from a background of injuries or nervous knees, start with the six-degree cleats. If you prefer a locked-in connection because it makes your power delivery more predictable, try the zero-degree option. Both are welcomed in the box, and switching is simple.

Why two cleat options matter

You will be glad that Favero included both cleat types because cleat choice changes not just comfort but the biomechanics of your pedal stroke. Often, riders change cleat type months apart, so having both at the outset saves time and money.

You should position your cleats carefully. Small adjustments in fore-aft placement or rotation can have outsized effects on comfort and performance. Take the time to set them up and test on a few short rides before committing to a long ride.

Ride feel and feedback on the road

You will notice that sensor-equipped pedals don’t alter the mechanical feel of your ride as much as your expectations. The Assioma UNO doesn’t intrude; it simply listens. The platform stiffness, the engagement, and the connection to the shoe feel familiar, with the addition of a quiet confidence that comes from accurate data.

You should pay attention to the sensation of pedaling during different efforts. The power numbers will follow your feelings of effort, sometimes validating them and sometimes challenging what you assume you did. That friction between perception and measurement is where your training finds clarity.

Noise, maintenance, and everyday use

You will sometimes hear a small click or feel the magnetic charger hang against the pedal surface when you attach it; these are minor and purposeful. The maintenance is minimal: keep the threads and contact points clean, check cleat bolts, and wipe away grit when you come inside.

You should not let drop-rides or occasional rain make you paranoid; the unit tolerates weather as part of its life. Still, routine checks are sensible: torque the pedals to specification periodically, and treat the unit like any precision tool you rely upon.

Using the data — training suggestions and drills

You want guidance that helps you move from data to improvement. Power is an honest, immediate number; how you use it matters. Start with basic, repeatable tests: a 20-minute threshold effort, a structured interval session, or a ladder of VO2 work.

You should record a baseline test and repeat it every four to eight weeks. Use the left/right balance metric after specific drills to see if single-leg work or cadence sessions influence your numbers. Small, consistent interventions produce the most sustainable gains.

Example sessions to try

You will find value in simple protocols: 4×8 minutes at threshold with 4 minutes recovery, sweet spot intervals at 88–94% of threshold, and cadence work where you spin for seated sets at high cadence to promote neuromuscular adaptation. After each session, compare torque efficiency and pedal smoothness.

You should use the balance metric to inform single-leg drills: try 3×8 minutes of single-leg spins on a trainer, alternating legs, with low resistance and high cadence. Record how balance shifts immediately after and in subsequent rides to observe trends.

Troubleshooting and support

You will occasionally meet friction when technology and the outdoors need to cohabit. Bluetooth dropouts, firmware quirks, or odd readings can occur with any electronic gadget. The Favero support community and documentation tend to be practical and responsive.

You should document issues precisely: note firmware versions, head unit models, ride conditions, and whether the pedals were paired to multiple devices. These details make troubleshooting faster and often reveal simple solutions, like updating firmware or re-pairing the sensors.

Common issues and fixes

You will sometimes see cadence not transmitted or readings that look spiky. Reboot the head unit, unpair and re-pair the pedals, and check firmware. If charging seems inconsistent, clean the magnetic contacts gently and ensure the connectors click into place. If problems persist, the manufacturer’s support is the next step.

You should keep your receipts and records handy if you need warranty support. Favero’s warranty and customer service are generally considered solid by riders who rely on these pedals daily.

Pros and cons

You will appreciate a balanced summary that respects nuance. The Assioma UNO is a considered product: it offers meaningful benefits while making clear trade-offs.

Pros:

• You get accurate left-side power with advanced pedal-based metrics at a price point below many dual-sided systems. These data allow you to train effectively and monitor changes in technique.
• Bluetooth and ANT+ compatibility mean seamless integration with most head units and apps. You will be able to broadcast to two devices if needed and analyze rides with your preferred tools.
• Rechargeable battery life of up to 50 hours and magnetic charging make routine use convenient. The automatic standby function reduces hassle and preserves battery life.
• Included cleats provide both float options, saving you a trip to the shop and giving immediate flexibility. The wear cloth is a thoughtful small touch.

Cons:

• Single-sided measurement extrapolates total power, which may be adequate for most but not all riders. If you are an athlete whose performance depends on precise bilateral data, a dual-sided system might be preferable.
• The pedals are not the lightest available; if your priority is shaving every gram, these feel like a compromise toward durability and functionality.
• Occasional firmware updates and pairing quirks are normal, which means you’ll need to spend a little time with software occasionally.

You should weigh these points against your goals. If you prize accurate, accessible power data that moves with you between bikes, this product earns its place.
