Magene PES P515 Alloy Power Meter Chainset 50/34T

The Magene PES P515 is a dual-sided, spider-based road power meter chainset with the PES alloy crank, the 99 g 7075 aluminium P515 spider and a 50/34T 110 BCD chainring set ready to bolt straight on. Upgraded from the P505 with ±1% accuracy, T47 and BB386 compatibility and a longer 330-hour battery life, it's a serious dual-sided crankset alternative to Shimano power meters at a fraction of the price - and a direct Hollowtech II swap for most road bikes.

Key Features

• Dual-sided spider-based power measurement: spider-mounted strain gauges with intelligent temperature compensation deliver true left/right power data with ±1% accuracy
• Built-in temperature compensation: tracks dynamic temperature shifts and corrects power readings, no drift on long climbs or freezing winter rides
• 330-hour battery life: rechargeable battery covers a full season of training and racing on a single charge
• 110 BCD 4-bolt chainring standard: wide compatibility with aftermarket chainrings and Shimano 12-speed compatibility for easy upgrades
• Magene QED chainrings included: 7075 aircraft-grade aluminium 4-bolt chainrings for crisp shifting and durable performance
• Triple hollow-channel alloy crank: CNC-machined PES alloy crank arm with deep-hole drilling balances stiffness and weight - tested to 100,000 hard pedal cycles
• 24 mm steel spindle: direct replacement for Shimano Hollowtech II cranksets - drop-in upgrade for most road bikes
• Opposing dual-bolt locking system: reduces non-drive-side crank loosening - a major improvement over previous Magene generations
• Bluetooth and ANT+ dual protocol: pairs with Magene, Garmin, Wahoo, Bryton, Hammerhead and any major head unit, plus Zwift, TrainerRoad, TrainingPeaks and Strava
• Advanced metrics: power, cadence, left/right balance and pedalling smoothness for proper performance analysis
• IPX7 waterproof: rides confidently through British weather and grim winter training blocks
• BB386 and T47 compatible: works with the major large-diameter bottom brackets, with standard Shimano-style threaded BBs also covered
