The reviewer tested the Magene P515 power meter on both PES alloy and TEO carbon cranksets over two months, finding that it performed well under pressure, unlike some recent competitors.

The Magene PES P515 Power Meter is an updated version of the P505, featuring minor improvements including slightly reduced weight (approximately 25g lighter), improved accuracy (1% vs 1.5%), better T47 bottom bracket compatibility, and active temperature compensation. It maintains the same price point as its predecessor. The power meter uses a 24mm steel spindle, 110mm 4-bolt BCD, and is compatible with standard road bike bottom brackets (68mm-86.5mm) including Shimano Threaded BSA setups. Installation requires standard tools plus a 44mm 16-notch bottom bracket wrench for the spider lock ring. Users report mixed experiences with compatibility, installation, and customer support, with additional concerns about preload bolt reliability—early versions had single-piece designs prone to loss, though Magene has since switched to a two-piece design. Replacement parts are available but may require international shipping. Some units have lock ring thread defects causing play in spider installation. Creaking issues have been reported but often originate from other components. Magene has released firmware updates (v0.118, upcoming v0.119) that improve performance, and the v0.119 firmware received a positive review from GPLama. A revised crankset design shown at the Shanghai bike show attaches from the drive side with a SRAM-style center bolt, potentially addressing creaking issues. The P515 is accurate with oval chainrings due to continuous angular velocity measurement.

Magene P515 : a nice powermeter, works well on my Wahoo Bolt and my Coros Pace. 250€ with coupons
My short experience with P515.
Sale via Ali from the EU shop went very well, delivery took 3-4 days more then expected. Crank looks very good, marginal heavier than the 105. Assembly was also no problem, I ordered it with the QED chainrings. Installation on my Lightcarbon LCR017 was not a big problem, I did however have to add a spacer on the drive side because otherwise there would have been play between the two arms. First 100k tour was also problem-free, recording in. Compared to the power meter pedals seems to be lower in the numbers, maybe still needs to be calibrated. What I also noticed is that the QED chainrings are louder than my 105 crank.
I hope this can help you a little.
Best regards.
