Favero Assioma Duo Power Meter Pedals Review 2026: Affordable Dual-Sided Power
Pedal-based power meters have become the easiest way to add power data to almost any bike without swapping a crankset, and the Favero Assioma Duo remains one of the most recommended dual-sided options for triathletes moving between a road bike and a TT bike. It swaps between bikes in minutes with a set of cleats and a pedal wrench.
Key Features
- Dual-sided measurement — strain gauges housed in each pedal spindle measure left and right leg power independently, rather than doubling one side like cheaper single-sided meters.
- IAV accuracy algorithm — Favero’s Instantaneous Angular Velocity system calculates true pedal velocity 200 times per revolution, with a claimed accuracy of ±1%.
- 50-hour battery life — rechargeable via a proprietary magnetic charger, with a low-battery warning sent to your head unit or watch.
- Dual protocol broadcast — transmits over both Bluetooth Smart and ANT+ simultaneously, so it pairs with a bike computer and a smart trainer app at the same time.
What We Like
At 305g for the pair, the Assioma Duo isn’t the lightest power meter on the market, but it undercuts Garmin’s Rally RS200 and Wahoo’s Powrlink Zero on price by a meaningful margin while measuring both legs independently — a genuine advantage for spotting a left/right power imbalance during rehab or off-season strength work. Because it’s pedal-based rather than crank-based, moving it between a road bike and a dedicated TT or tri bike takes minutes rather than a full drivetrain swap.
Where It Falls Short
You’ll need pedal wrench access and a compatible cleat system — this isn’t a five-minute fit if you’re not used to swapping pedals. The magnetic charging cable is also a small, easy-to-lose part, so keep it somewhere you won’t misplace it between race weekends.
Verdict
For triathletes who want real dual-sided power data without committing to a crank-based system — or who split time between two bikes — the Assioma Duo is one of the most cost-effective ways in. It won’t be the last power meter you consider, but it’s a sound one to start with.
