Favero Assioma DUO-Shi Power Meter Spindles
The all new Favero Assioma DUO-Shi Power Meter Spindles allow Shimano users to enjoy one of the best-selling power meters on the market! The DUO-Shi Power Meter Spindles consist of two special pedal spindles that can be quickly and easily installed into your current Shimano SPD-SL pedal bodies. Therefore, you can experience everything the Assioma DUO has to offer while keeping the Shimano pedals you have grown to love. In addition, the DUO-Shi is compatible with Shimano PD-R8000, PD-R7000, PD-6800, PD-R550 and PD-R540 pedal bodies.
The Favero Assioma DUO-Shi’s feature all of the power meter technology found in the original DUO. This includes IAV power with +/- 1.0% accuracy, IAV cycling dynamics, Favero’s user friendly app and more. In addition, these DUO-Shi spindles are a dual-sided power meter with a power sensor located in each spindle. This means the power meter can show both left and right leg power, in addition to total power and cadence.
Important Note on Q Factor
The Favero Assioma DUO-Shi Power Meter has a Q Factor of 64-65 mm. This compares to 53-54 mm for most other pedals. This means each pedal will be approximately 10-12 mm further away from the bike than normal. Since Q Factor and bike set-up is subjective, each rider needs to determine if this is an ideal set-up for them.

Favero IAV Power TechnologyFavero Assioma IAV Power Graph
The Assioma uses Favero’s IAV (Instantaneous Angular Velocity) Power. Using special software and a built-in three-axis gyroscope, IAV takes into account the precise pedaling speed within each pedal stroke. This results in the Favero Assioma DUO-Shi having accuracy of +/- 1.0%. In addition, IAV allows you to use the Assioma pedals with oval chainrings without any impact to the accuracy of your data!

Favero’s gyroscope also allows you to measure cycling dynamics data. IAV Power Phase displays the portion of your pedaling stroke in which torque is produced. In addition, your Power Phase Peak, in which maximum torque is produced, is also indicated. IAV Rider Position displays the portion of time you are in a seated vs. standing position. This allows you to analyze how a specific position can influence your performance. This data works with most Garmin bike computers including the Edge 1030, 830, 820, 530 and 520 Plus.
