Magene PES P515: The power meter that redefines performance-to-quality ratio
If there's one accessory that can truly make a difference in a cyclist's training, it's a power meter. But how many of us have encountered exorbitant prices, compatibility issues, or disappointing performance? That's why today we're talking about the Magene PES P515 , a power meter that succeeds where many fail: combining advanced technology, reliable data, and an affordable price . But let's take it one step at a time.
Accuracy ±1%: real power, truly measured
At the heart of the P515 is a spider-based meter featuring strain sensors and high-precision accelerometers. The most impressive data? A power reading accuracy of ±1% . This means that every watt you push is reliably recorded, even in challenging environmental conditions, thanks to a built-in temperature compensation algorithm .
It’s the perfect tool for anyone who wants to stop “going by feel” and start building workouts based on solid data , both on the road and indoors.
Designed to last, built to push
The PES crankset design is immediately striking: triple cable channels , CNC machining, and deep drilling, for the perfect balance between stiffness and lightness. The result? A total weight of 625g (170mm) and a resistance that has exceeded 100,000 pedal cycles in laboratory tests.
The power meter itself weighs just 99g , and is made from 7075 aircraft-grade aluminum . This is no coincidence, as it ensures lightness without sacrificing rigidity.
4 key data to analyze every pedal stroke
The Magene P515 doesn't just measure watts: it helps you understand how you express them .
-
Power : precise and reliable up to 2500W
-
Cadence : always stable, between 20 and 240 RPM
-
Left/Right Balance : Useful for working on any asymmetries
-
Pedaling fluidity : to refine the technical gesture and improve efficiency
240 hours of battery life: and battery life is no longer a concern
One of the P515's strong points is its incredible battery life : up to 240 hours of use on a single charge. This is thanks to the new low-power circuitry and convenient, safe magnetic charging . You'll never have to worry about running out of data in the middle of an outing or an indoor session again.
Compatibility and installation: all included, all ready
The P515 comes complete with a spider, PES20 crankset, charging cable, stickers, instructions, and—in the full version—dedicated Magene chainrings to ensure maximum compatibility and smooth shifting. No awkward joints or components to purchase separately: it installs easily and doesn't cause problems with Shimano drivetrains (thanks to the 24mm steel spindle, a widespread and reliable standard).
It is also compatible with wider bottom brackets such as T47 and BB386 , respecting certain measurements (width from 90.5 to 92mm and max external diameter 57mm).
Bluetooth and ANT+: All your data, wherever you want
Of course, it supports Bluetooth and ANT+ , so it connects perfectly to all the main cycle computers (Magene, Garmin, Bryton...) and to the most used training platforms: Zwift, TrainerRoad, TrainingPeaks, Strava, Onelap , and many others.
Whether you ride on rollers, outdoors, or both, the P515 adapts to you, not the other way around .
In conclusion: who do we recommend it to?
For those looking for a serious, accurate, robust, and no-frills power meter , but without spending a fortune. The Magene PES P515 proves that you don't have to break the bank to train wisely —quite the opposite. It's suitable for the ambitious novice as well as the experienced cyclist who wants a reliable second meter, perhaps for their training bike.
Giant steps, watt after watt.
