PES P515 Power Meter Alloy Cranks

Built from premium materials and engineered for consistent performance in all conditions, it delivers accurate data, smooth power transfer, and broad compatibility for modern road bikes.The crank features a triple-hollow channel design, CNC machining, and deep-hole drilling to reduce weight while maximising structural strength. After 100,000 cycles of harsh pedalling tests, the system maintains its stiffness and reliability. The spider itself is crafted from 7075 aircraft‑grade aluminium, weighing only 99g, balancing low weight with exceptional rigidity.The P515 provides four essential cycling metrics, power, cadence, left/right balance, and pedalling smoothness, allowing riders to analyse their technique and training efficiency in detail. With an impressive 330-hour battery life, it supports long-distance training and multi-day rides without frequent charging.±1% Power Accuracy, Capture Your Every Effort AccuratelyThe P515 spider-based power meter employs high-precision strain gauges and acceleration sensors. Combined with built-in intelligent temperature compensation algorithms, it can provide precise and reliable power data anytime and anywhere, even when the environment changes constantly. Extensively tested in harsh environments with highly demanded standards, and with each strain gauge undergoing stress release, the product guarantees a ±1% power accuracy, never letting your effort in vain.4 Essential Cycling Data: Evaluate Your Cycling Ability ComprehensivelyPower: 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.Pedalling smoothness: Analyse the power data balance of your pedalling cycles.SpecificationsWeight:625g (170mm)Spinde: 24mmBolts: 4 boltChainline: 44.25mmQ-Factor: 147mmPower range: 0 - 2500WCadence range: 20 - 240RPMCalibration: Automatic, Backpedal and manualWireless: ANT+ and BluetoothWaterproof grade: IPX7Working temperature: -20 to 50 degreesCharging: MagneticWhat's in the box?P515 Spider-based power meterpair of PES crank armsLock ring of conversion kitMagnetic charging cableX6 StickersQuick start guideFeatures & Benefits±1% power accuracy using high‑precision strain gauges and acceleration sensorsIntelligent temperature compensation for consistent readings in changing environmentsTriple-hollow crank design for reduced weight and increased stiffness330-hour battery life for long‑term training and endurance rides110 BCD 4-bolt compatibility with Magene and third‑party chainrings24mm steel spindle compatible with Shimano and major bottom-bracket standardsBluetooth and ANT+ connectivity for multi‑device data recordingDurability tested with over 100,000 pedalling cycles
