Magene Cycling PES P515 Powermeter 165-175mm Crank Length Options
SKU code: FES-PES-P515-165
Pre-order - Released 3 October 2026
Accurate power data without the premium price. The Magene PES P515 pairs a spider-based power meter with PES crank arms and a 24mm steel spindle, giving road and gravel riders ±1% accurate power, cadence and balance data on the head unit or app they already use.
Highlights
- Spider-based power meter, accurate to ±1%
- Power, cadence, left/right balance and pedalling smoothness
- ANT+ and Bluetooth: works with Magene, Garmin and Bryton computers plus apps like Zwift and Strava
- Up to 380 hours of battery life (lab figure), magnetic charging
- IPX7 water resistance; 24mm steel spindle; 4-bolt 110BCD
- Five crank lengths: 165mm, 167.5mm, 170mm, 172.5mm, 175mm
Measurement you can trust
High-precision strain gauges with temperature compensation give ±1% accuracy across a 0 to 2500W range and 20 to 240rpm cadence. Automatic, backpedal and manual calibration keep readings honest as conditions change.
Built for long rides and bad weather
Magene quotes up to 380 hours of riding per charge in lab testing (real-world life depends on temperature and use). The unit is IPX7 rated and operates from -20°C to 50°C, and recharges with a magnetic cable.
What's in the box
P515 spider power meter, a pair of PES crank arms with 24mm spindle, magnetic charging cable, quick start guide, stickers and a lock ring. Chainrings are not included; the spider takes standard 4-bolt 110BCD rings.
