Favero Assioma DUO shi

The Assioma DUO-Shi road power meter was designed for cyclists who favour the Shimano® road standard, allowing them to continue riding with their own Shimano® SPD-SL® pedal bodies* without giving up Assioma's reliability and accuracy.

Assioma DUO-Shi is compatible with the following Shimano® SPD-SL® pedal bodies: PD-R8000, PD-R7000, PD-6800, PD-R550 and PD-R540.

Installation in your own Shimano® pedal bodies:

• Installing the Assioma DUO-Shi power sensor in your own compatible Shimano® SPD-SL® pedal bodies* is quick and easy.

Increased Q-factor?

• The Q-factor of the Look® version of Assioma is +54mm, while Assioma DUO-Shi measures +64mm with PD-R7000/R550/R540 pedal bodies and +65mm with PD-R8000/6800 pedal bodies.
• Despite some initial hesitation about the increased Q-factor, we decided to proceed with the project, taking into account that our body dimensions (weight, hip width, etc.) are individual factors that can help determine the most suitable Q-factor for each of us.
• Positive feedback from our beta testers provided the final validation for the product.

Easy to install:

• Assioma DUO-Shi power sensors can be installed and moved from one bike to another just like a standard pedal: in a few minutes, without special tools or a mechanic's assistance.

IAV Cycling Dynamics:

• Our power meters provide advanced metrics such as IAV Cycling Dynamics (IAV Power Phase and IAV Rider Position) which, together with conventional power data, allow detailed analysis of pedalling technique and how the rider's position on the bike affects performance.

IAV Power system and gyroscope:

• Unlike other power meters, Assioma's measurements account for irregular pedalling (e.g. sprints, climbs) or the use of oval chainrings when calculating power, ensuring accuracy of ±1% in any situation. This is because Assioma can detect the actual instantaneous angular velocity of the pedal stroke.

Bluetooth and ANT+:

• Assioma DUO-Shi features Bluetooth and ANT+ technology for reliable data transmission to both cycling computers and Android and iOS smartphones.

True right/left balance data:

• The data provided by the Assioma DUO-Shi SPD-SL® dual-sided power meter is based on measurements taken separately on the right and left sides, allowing accurate monitoring of both total power and left/right balance.

Measurement stability:

• Thanks in part to ATC (Automatic Temperature Compensation), our power meter ensures accuracy, repeatability and consistency of measurements in real road riding conditions and at any temperature between -10°C and 60°C.

Waterproof, durable and lightweight:

• Protected by a block of two-component resin, our power meter's sensor is extremely impact-resistant and completely waterproof.

Rechargeable and eco-friendly:

• Favero Assioma DUO-Shi uses built-in rechargeable batteries: a single charge guarantees at least 50 hours of use.
  

Tested and guaranteed:

• Favero Electronics manufactures every power meter at its own premises in Italy and checks each one individually through thorough laboratory testing, comfortably exceeding the standards required by current regulations.
