Frequently Asked Questions: Favero Assioma Power Pedals

Frequently Asked Questions

What is the difference between Favero Assioma PRO RS and Assioma Duo-Shi?

The Favero Assioma PRO RS (RS-1 / RS-2) is a complete, ready-to-ride native Shimano SPD-SL power meter pedal with a standard 53 mm Q-factor and ultra-low 10.5 mm stack height—all electronics and batteries are sealed inside the spindle with no external pod. The Assioma Duo-Shi consists of adapter spindles that install into your own Shimano pedal bodies and results in a wider 64–65 mm Q-factor.

Why are Favero Assioma power meters accurate with oval chainrings?

Unlike power meters that calculate wattage using average cadence per revolution, every Favero Assioma pedal integrates a 3-axis gyroscope and IAV (Instantaneous Angular Velocity) technology. It measures the exact angular velocity throughout every millisecond of the pedal stroke, guaranteeing true ±1.0% accuracy even with non-round/oval chainrings.

Does Threshold Cycling ship Favero Assioma pedals from the USA with an official warranty?

Yes. Threshold Cycling is an Authorized US Favero Electronics Dealer. All in-stock Assioma power meters ship directly from our Virginia headquarters with fast tracked domestic delivery (zero customs fees) and include the full 2-Year Official Favero Manufacturer Warranty.
