The Assioma DUO-Shi Power Meter Pedal Axles bring Favero power meters to your Shimano road bike pedals

The Assioma DUO-Shi Power Meter pedal axle kit by Favero includes a right as well as a left axle that are compatible with certain Shimano SPD-SL pedal bodies and have each been equipped with a power meter. This means that users of the PD-R8000 and other Shimano pedals can also enjoy the highly accurate, dual-sided power measurement that has long proven itself on Look-compatible pedals from Favero. Not only can you check your performance, left-right balance and round pedalling--the kit also opens up access to other aspects of performance development with IAV Cycling Dynamics. Thanks to a built-in gyroscope, these power meter pedal axles also work reliably when you use oval chainrings. Assioma DUO-Shi also scores with quick, easy installation, ANT+ and Bluetooth wireless technology and automatic temperature compensation.

Läuft perfekt mit PD-M520 Pedalkörper (die exakt gleiche Achsenkonstruktion verwenden, wie die offiziell unterstützten PD-R540. Durch die seitliche Versellbarkeit der SPD-Cleats keinerlei Probleme mit dem Q-Factor-Zuwachs.

Leichte Montage. Top verpackt. Laufen bei mir mit einem garmin Edge 530. Läuft und synchronisiert perfekt. Der Q Faktor spielt bei mir überhaupt keine Rolle (1,8m/88kg). Auch nach längeren Ausfahrten merke ich davon nix. Preis Leistung unschlagbar.
