Highlights
- 【±1.5% Power Accuracy for Reliable Data】With a dual-sensor fusion algorithm that integrates high-sensitivity strain gauges with an accelerometer, it monitors ambient temperature in real-time and dynamically compensates for measurement discrepancy, ensuring unwavering accuracy and stability.
- 【Lightweight 680g Aluminum Structure】The crank is forged from 6061 aluminum alloy for superior mechanics; the spider is fully CNC-machined from 7075 aluminum alloy, with an optimized structure. The total weight is 680g (170mm crank + 100g spider), delivering maximum stiffness and efficiency.
- 【300h Battery & Magnetic Charge】Ride farther without worry. The intelligent power management system delivers up to 300 hours of use per charge, while the magnetic snap-on charger ensures effortless, secure recharging anytime.
- 【4 Core Data Points - Smart Ride Analysis】Your ride data is more than numbers. With Power Quadrant Analysis and Left-Right Balance Tracking, the GEOID PM500 monitors Power (±1.5%), Cadence (20–240RPM), Left-Right Balance, and Pedaling Smoothness, helping you spot efficiency gaps, refine technique, and train scientifically.
- 【Easy Setup & Ready to Use】The complete set includes the PM500 spider power meter and Senicx PR3 crank - a perfect match. With its 110 BCD 4-bolt design, it is compatible with all 110BCD standard 4-bolt chainrings. You can switch between single and double chainrings at will. It is perfectly compatible with SHIMANO's 12-speed system.
- 【Bluetooth/ANT+ Dual Connectivity】Equipped with dual-protocol support, it ensures broad compatibility with bike computer from GEOID, Garmin, Wahoo, Magene, and more. Seamlessly sync your data to platforms like STRAVA, Zwift, and TrainingPeaks. Every ride is automatically recorded across multiple devices and can be shared instantly with a single tap—delivering a perfectly smooth, integrated experience.
- 【IPX7 Waterproof - Stable Under Heavy Rain】Rigorously tested for waterproof under static and dynamic conditions, it meets the IPX7 standard to perform reliably in complex riding environments. Whether in downpours or muddy terrain, it maintains consistent performance.（Measured by GEOlD Laboratory）
