Magene - PES P515 Power Meter

±1% Accuracy, Every Watt Counts

The P515 spider power meter uses high-precision strain gauges and acceleration sensors. Thanks to the built-in intelligent temperature compensation algorithm, it provides accurate and reliable data under any environmental conditions. Tested in extreme environments and subjected to rigorous quality standards, each strain gauge is treated with internal stress relief, ensuring power accuracy of ±1%. No effort will be wasted.

Lightweight 625g Design and High Rigidity, Unleash Your Full Power

The PES crankset features a three-channel hollow design, significantly reducing weight. It's a one-piece construction using high-precision CNC machining and deep drilling. The symmetrical structure optimizes force distribution, while the sealing technique ensures strength and durability. Even after 100,000 cycles of intense pedaling, performance remains excellent.

The P515 meter is made from 7075 aircraft-grade aluminum: premium materials that reduce weight to just 99g while maintaining high rigidity.

4 Essential Data for a Complete Analysis

• Power : Precise and responsive measurement, with ±1% accuracy.

• Cadence : Reliable and stable data to always maintain the optimal pace.

• Left-Right Balance : Monitor the difference between the two legs to improve the weaker leg.

• Pedaling Smoothness : Analyzes the balance of force during each pedal rotation.

Up to 240 Hours of Battery Life, Uninterrupted Training

The new electronic circuit design optimizes energy efficiency and reduces power loss. A full charge provides up to 240 hours of continuous use, ideal for intense and prolonged workouts.
Battery life tested in Magene labs; may vary depending on environment.
