PES 515 POWER METER CRANK

4 Essential Cycling Data, Evaluate Your Cycling Ability Comprehensively

Power: Sensitive and reliable power measurement, reaching ±1% accuracy. 

Cadence: Accurate and stable cadence data measurement always keeps your rhythm in control.

Left and right balance: Know the difference between your left leg and right leg output, so as to enhance training of the weaker leg.

Pedaling smoothness: Analyze power data balance of your pedaling cycles.

 Perfect for:

• Budget-conscious cyclists wanting their first power meter
• Training enthusiasts who prioritize accuracy over weight
• Riders with Shimano groupsets seeking easy compatibility
• Cyclists with T47 bottom brackets (now supported in P515)

Why Choose the P515?

Best value for spider-based measurement: The P515 offers true total power measurement (not doubled estimates) at the lowest price point. While heavier than crank-based options, it provides more accurate total power readings.

Exceptional battery life: At 330+ hours, the P515 outlasts most competitors by 2-3x, reducing maintenance hassle.

Future-proof compatibility: T47 support and Shimano integration make it ideal for modern bike builds.

The power meter works perfectly out of the box. You have to initially configure it via the Magene App and you can also update the firmware there.

After that you can pair it with your GPS Head Unit, from which you can also start the calibration. I typically calibrate the power meter 10-15 min into the ride to get accurate readings.

I had no connectivity dropouts and the power meter also reports the cadence so no separate cadence sensor needed.

The left and right balance is estimated from the pedal position, but what matters the most are accurate total power readings which work fine due to the nature of the power meter being between the crankset and chainring (spider power meter)
