Rider reviewed
GEOID
GEOID PM500 spider-based power meter crank offering dual-sensor strain gauge measurement with real-time temperature compensation for stable readings. Reports power, cadence, left-right balance and pedalling smoothness over ANT+ and Bluetooth, with a claimed accuracy of ±1.5% and roughly 300 hours of battery life from a magnetic charging connection. Built on a 110 BCD 4-bolt spider with a 24mm spindle, compatible with Shimano 11/12-speed road drivetrains only (not compatible with GRX 1X/2X or 10-speed and below). Suited to road riders wanting entry-level structured power training without the cost of a premium meter.
