Magene PES P515 Cycling Power Meter

The P515 spider-based power meter uses high-precision strain gauges and accelerometers. Together with built-in smart temperature compensation algorithms, it provides accurate and reliable power data anytime, anywhere, even in constantly changing environmental conditions. The product has been thoroughly tested to strict requirements, including in extreme environmental conditions, and every strain gauge has undergone a stress-relief process. As a result, it delivers ±1% power accuracy so every effort can be recorded precisely.

The PES crankset uses a three-chamber hollow design. The large cavities significantly reduce weight. The crank is made in one piece using precision CNC machining and deep-hole drilling technology. Alongside optimised sealing technology, the symmetrical design significantly improves load distribution. This greatly reduces weight without reducing performance. It still performs excellently after 100,000 intensive pedalling cycles.

The P515 spider-based power meter is made from aerospace-grade 7075 aluminium. Thanks to premium material choices, it provides excellent stiffness at low weight, so the power meter weighs just 99 g.

Power: Sensitive and reliable power measurement with accuracy up to ±1%.

Cadence: Accurate and stable cadence measurement so you always stay in control of your rhythm.

Left–right balance: Learn the difference between the power of your left and right legs, so you can develop the weaker side more specifically.

Pedal smoothness: Analyse power distribution throughout the pedal stroke.

The P515 spider-based power meter uses a new circuit design that ensures more efficient energy use and lower power consumption while riding. After a full charge, it allows up to 380 hours of long-distance riding and training.

*Battery life was tested in the Magene laboratory and may be affected by environmental conditions and temperature.

The PES P515 power meter set includes the P515 spider-based power meter and the PES20 crankset. Thanks to the well-thought-out combination, you don't have to worry about choosing compatible parts separately. This ensures consistent and reliable performance without worrying about compatibility issues from third-party parts.

The P515 spider-based power meter uses the widely used 110 BCD four-bolt standard, making it compatible with many cranksets. We also offer an exclusive chainring for it. With the QED split chainring, you can build a complete P515 spider-based power meter crankset to suit your needs. With Magene's original chainring, you can enjoy even more efficient shifting and a smoother pedalling experience.

The PES crankset uses a 24 mm steel spindle, a widely used standard on the market. It is compatible with bottom brackets used on conventional road bikes.

With a SHIMANO system, the crankset can be fitted directly without replacing the bottom bracket.

Also compatible with oversized bottom brackets, including the T47 and BB386 standards.

1. Outer diameter of the drive-side bottom bracket shell: ≤57 mm
2. Total width of the bottom bracket shell after installing the bottom bracket: 90.5–92 mm

Compatible with many ANT+ and Bluetooth devices, it connects to bike computers from Magene, Garmin and Bryton, among others, and to training apps such as STRAVA, Onelap, OnelapFit, Zwift, TrainingPeaks and TrainerRoad. This lets you record data on multiple devices and apps during a single workout.
