Garmin Rally RS200
Garmin Rally RS200 is positioned as a premium, dual-sided pedal power meter that stands out for tight integration with Garmin head units and a turnkey pedal platform that’s easy to transfer between bikes. It justifies its higher price with features like comprehensive left/right metrics, advanced firmware ecosystem, and easy serviceability, making it technically more flexible than crank/spider solutions (Quarq) and more fully featured than many single-sided options (4iiii, Stages). For riders who want plug-and-play dual-sided data and seamless Garmin device pairing, the RS200 is a market-leading choice.

4iiii Precision 3+ Left-Side
4iiii Precision 3+ Left-Side is a single-sided, left-crank power meter aimed at budget-conscious cyclists who need accurate, reliable power data without paying for dual-sided hardware. Its low cost and easy installation make it financially attractive compared with dual-sided pedals and crank/spider units, and users can upgrade to dual-sided setups later or rely on power-estimation strategies for training usefulness. Technically it’s lighter and simpler than pedal systems (Garmin/Favero) and remains a strong value option for training-focused riders.

Quarq DZero DUB
Quarq DZero DUB is a spider-based power meter that measures total crank power at the spider, offering very stable, drivetrain-agnostic readings and strong compatibility with integrated cranksets favored by road and time-trial cyclists. Technically it delivers consistent accuracy and durability compared with pedal-based systems and avoids pedal-compatibility issues, though it typically sits at a higher price point than single-sided crank arms (Stages, 4iiii) and isn’t as instantly transferable between bikes as pedal-based solutions. For riders who want a robust, crank-mounted total-power solution and prioritize long-term stability over pedal swapability, the DZero DUB is a top contender.
