According to the product specialist

Pros
Lightweight and stiff CNC-machined aluminium crankset.
Compatible with Rotor direct mount chainrings and, by using a spider, with Shimano chainrings.
Highly accurate power measurement with an accuracy deviation of +/- 1.5%.
Can be used with all bike frames because the power meter is incorporated into the crank.
A double-sided power meter allows you to measure the power transmission of both legs individually.
Thanks to the Automatic Terrain Selector, you are assured of accurate power measurement on different types of terrain.
With an IPX7 waterproof rating and a battery life of up to 550 hours, you are guaranteed endless fun.
Very accurate force determination with a deviation of up to 1%.
Suitable for Shimano 12-speed cranksets.
