The Magene TEO P515 is a power meter system designed for cyclists seeking reliable power measurement with lightweight and high stiffness. It combines carbon crank arms with an aluminum spider, providing immediate response during pedaling and an accuracy of ±1%. Weighing only 425 g (including all components), it is a particularly lightweight choice for road riders who want to improve training and performance.

• Lightweight & stiff carbon crankset
• Constructed from HI‑MOD carbon for maximum stiffness and direct power transfer.
• Real weight of the arm approximately 325 g (170 mm), total system weight 425 g after installation.
• Aluminum power‑meter spider with an accuracy of ±1%, made from 7075 aircraft-grade aluminum.
• Uses strain gauges and acceleration sensors for stable measurement.
• Smart temperature compensation for accurate readings under changing conditions.
• Long-lasting battery: 330 hours of operation on a single charge.
• 29mm spindle for greater stiffness and durability, made from 7075 aluminum.
• Wide compatibility: 110 BCD – 4 bolt, compatible with most chainrings on the market.
• ANT+ & Bluetooth for connection to GPS computers and apps.
• IPX7 waterproofing for use in all weather conditions.

The system offers all the essential and training-related measurements:

• Total power (W)
• Cadence (RPM)
• Estimated left-right power balance
• Pedaling smoothness/efficiency

These measurements help the cyclist understand how much power they are really generating, how they distribute power between their legs, and how to improve technique and efficiency. According to independent reviews, the P515 is considered one of the most comprehensive and affordable solutions in the spider-based category.
