Magene P505 Power Meter Review: Details // Data // Lama Lab Tested

The Magene P505 is a well priced spider-based cycling power meter with a number of options available to fit different cranks and chainring combinations. I’ve been riding the P505 since February 2022 and have collected over 70 comparative data sets against other power meters and smart trainers. To keep things short, this video covers the data from three recent rides across indoor, road, and gravel with the latest firmware that is being released this week.
