Magene PES P515 Power Meter Chainset

The Magene PES P515 Power Meter Chainset is a high-precision spider-based power meter and crankset system built to deliver accurate training data, strong power transfer, and dependable long-distance performance. With ±1% power accuracy, intelligent temperature compensation, and a rigid yet lightweight crank design, it provides reliable data for structured training and consistent riding performance. Premium materials, advanced construction, and long battery life ensure stable power measurement and efficient drivetrain performance across demanding road conditions.

Key Features and Benefits:

• ±1% power accuracy using high-precision strain gauges and acceleration sensors: These sensors measure pedalling force and rotational speed with exceptional precision. The system calculates power output with minimal deviation from actual effort, giving you reliable data that supports accurate training analysis and performance tracking.
• Intelligent temperature compensation system: Built-in algorithms adjust power readings when temperatures change during a ride. This maintains consistent measurement accuracy in cold mornings, warm afternoons, and long rides, ensuring the data remains dependable in real-world conditions.
• Spider-based power meter design: The spider position measures total power directly from the drivetrain’s central load point. This provides stable and balanced readings across both crank arms, producing reliable total power data that reflects real pedalling output.
• Triple-hollow crank arm construction: CNC machining, internal hollow channels, and deep-hole drilling remove excess material without weakening the structure. The result is a crankset that stays stiff under load while reducing weight, improving pedalling efficiency and power transfer.
• 7075 aircraft-grade aluminium spider weighing only 99g: This high-strength aluminium alloy offers excellent rigidity while maintaining a very low weight. The structure resists flex under heavy pedalling loads, helping maintain accurate power measurement and drivetrain stability.
• 330-hour rechargeable battery life with magnetic charging: The integrated battery supports extended training blocks and long endurance rides without frequent recharging. Magnetic charging keeps the system easy to maintain and ensures the power meter remains ready for regular use.
• Advanced cycling metrics including power, cadence, left/right balance and pedalling smoothness: These measurements provide detailed insight into pedalling technique and output distribution. The data helps identify inefficiencies and supports structured training improvements.
• Broad compatibility with modern road drivetrains: The 24mm steel spindle fits Shimano and other common bottom bracket standards, while the 110 BCD 4-bolt interface supports Magene and third-party chainrings. This allows easy integration into many road bike setups.

Reliable power measurement is essential for structured training and consistent performance tracking. The Magene PES P515 delivers stable data through its spider-based measurement system, precision strain gauges, and intelligent temperature control. The rigid triple-hollow crank design and 7075 aluminium spider maintain drivetrain stiffness under load, ensuring power readings remain consistent even during high-intensity efforts. Combined with detailed cycling metrics and long battery life, the system supports efficient training analysis across daily rides, endurance sessions, and performance testing.

For riders who rely on accurate power data and durable drivetrain performance, the Magene PES P515 Power Meter Chainset provides a dependable training tool built for consistent results. Its precision sensors, strong construction, and long battery life make it a practical upgrade for riders who want reliable data on every ride.
