Créé le : 4 juillet 2025The reviewer tests and reviews the Magene PES515 power meter, which is a spider-based power meter that comes with a PES crankset. They detail the unboxing, installation on a bike with a Shimano groupset, and extensive testing against other power meters. The reviewer notes the initial accuracy was off by 4-5% compared to their reference pedals, but after applying a calibration offset in the app, it showed excellent precision and repeatability. They conclude it is a very affordable option that requires some user calibration to achieve accuracy.
