"Get real, people! Pedal-based power meters are a game-changer for serious cyclists. Look Keo Power and Garmin Rally systems can't be compared apples-to-apples. Keo Power's dual-sided measurement and advanced metrics are for pros who want to shave seconds off their times, while Rally's single-sided simplicity is for casual riders who just want to track their coffee shop spins. Don't even get me started on installation and calibration - if you can't handle the complexity, stick with a basic bike computer!"
