Assioma Duo power meter

Unleash your power, ride hard facts

Breakthrough technology applied to cycling, to make your training more efficient and effective than ever. Set your targets with ultraprecise and reliable watt measurements. Hard facts, not estimates, to make the most of each pedal stroke.


Features

  • Easy to install, fast to move between bikes
    Install and move your Assioma power meter from one bike to another just like a normal pedal, easily and without special tools.
    Pair it with your bike computer or smartphone instantly via Bluetooth and ANT+.
  • Pedaling analytics, not just power and cadence
    Assioma power sensors are placed on the pedals, exactly where your force is applied, to provide you with a more detailed and accurate observation of your pedal strokes, which includes the following data:

Left/Right Balance
Indicates, as a percentage, the power individually generated by the left leg and the right leg.
The L/R Power Balance values allow you to monitor the dominant/non-dominant leg ratio and observe how this varies in relation to different racing and fitness conditions. This can be useful to correct penalizing imbalances: also in post-traumatic rehabilitation programs.

Torque Effectiveness
Indicates, as a percentage, how much of the power generated during one pedal stroke actually contributed to the propulsion of the cyclist.
This value is based on the Positive Power (P +), that pushed the pedal forward, and the Negative Power (P -), that pushed in the opposite direction, applied to the crank over each revolution.
Negative Power can be countered by helping the foot to "go back up" in the recovery phase: pulling it by the engaged shoe.
A 100% Torque Effectiveness occurs when no Negative Power has been accumulated during a pedal stroke. The typical TE value may vary between 60% and 100%.
Assioma DUO provides data for both left and right leg.

Pedal Smoothness
Indicates, as a percentage, how evenly distributed the power is in a full revolution of a pedal stroke. A value of 100% means that the power is delivered constantly throughout all the revolution: the higher the value the "rounder" the pedaling. Pedal Smoothness is identified by correlating the Average Power (Pavg) with the Maximum Power (Pmax) measured in a single 360° rotation of the pedal. Assioma DUO provides separate data for both the left and the right leg.

The only one with IAV Power system
Many power meters calculate power using the average angular velocity (AVG) per rotation instead of the instantaneous angular velocity (REAL) value: this may introduce an additional error, up to 4.5% compared to the declared accuracy.
Assioma, thanks to its exclusive IAV Power system and an integrated gyroscope, measures the actual instantaneous angular velocity to guarantee the same ±1% degree of accuracy with any style of pedaling, even with oval chainrings.

  • Automatic Temperature Compensation
    Rain, snow, mud, or sweltering heat: automatic temperature compensation (ATC) ensures exact, consistent watt measurements in any weather condition at temperatures between -10°C and 60°C.
  • Waterproof, resistant and the lightest ever made
    The lightest and most compact pedal-based power meter: with no protrudin elements, it does not interfere with the pedalling. Not eve when cornering. Protected by a bi-component resin block, the power meter sensor is extremely resistant shocks and fully waterproof.
  • No waste of energy or time

Rechargeable batteries
The lithium-ion technology provides a long battery life: up to 50 hrs with a single charge.

Automatic stand-by
After a few minutes of inactivity, Assioma automatically sets to stand-by and instantly switches on as soon as you start pedaling.

Magnetic connectors
You can recharge your cycling power meters simultaneously thanks to the battery charger with double USB cable and magnetic connectors.

  • Extreme compatibility

Mobile devices
With Bluetooth and ANT+ technology easily connect the power meter to almost any bike computer and smartphone.

Shoes and cleats
Assioma can be used with the cleats supplied or with original Look Kéo cleats, and it is easily adjustable to any current footwear on the market.

Crank-arms
Assioma is a pedal-based power meter compatible with any road bicycle crank-arm.

Total weight per pedal: 152,4 g.
