Magene P715S Dual Sided Pedal Power Meter SPD-SL  The Magene P715 S is the perfect power solution for riders who want to keep the familiar feel and wide-platform stability of their Shimano SPD-SL setup. By integrating dual-sided power sensing into a 159g pedal body, this model allows you to transition to pro-level data tracking without needing to swap your cleats or learn a new clip-in muscle memory. The system captures your output with ±1% accuracy, using an internal gyroscope and temperature-compensation algorithms to ensure your wattage stays precise during high-cadence sprints or freezing mountain descents.  Beyond just measuring raw effort, the P715 S provides a complete biomechanical breakdown, including left/right balance, torque effectiveness, and pedaling smoothness. With 120 hours of battery life and a simple magnetic charging system, it offers a massive endurance range for long training blocks. Installation takes less than a minute with a standard wrench, making it incredibly easy to move your power data between bikes while maintaining the reliable engagement and durability of the Shimano road standard.
