The Rally RS200 offers dual-sensing power with left/right cadence and balance metrics, helping riders optimize climbing and sprint performance. Installation is designed for rapid bike transfers, making it practical for riders who switch between bikes or rides multiple setups. It integrates smoothly with the Garmin ecosystem, allowing data synchronization with Garmin watches, Edge devices, and compatible apps for a unified training history. The RS200 supports ANT+ and Bluetooth connections for versatile device compatibility.
Buying Guide
Power Meter Type And Sensing
Pedal-based meters (like the P715 S, MX-1, XC200, and RS200) deliver direct measurements at the crank or pedal, capturing data through individual sensors. Dual-sensing models (XC200, RS200) measure both crank torque and cadence, enabling more accurate total power and left/right balance. Crankset meters (PES series) can offer excellent stiffness and robustness but may require crank compatibility checks before purchase.
Compatibility And Installation
Consider compatibility with your bike’s drivetrain and cleat system. MTB riders commonly use SPD or SPD-SL configurations, so pedal-based meters should match the cleat you own. Installation speed matters for training continuity; look for options advertised as quick to install and easy to transfer between bikes. ANT+ and Bluetooth support are essential for broader compatibility with head units, phones, and training apps.
Battery Life And Durability
Battery life varies from model to model; pedal-based meters often offer hundreds of hours, while some cranksets emphasize long runtime in hours. Waterproofing and IP ratings indicate durability in muddy or wet conditions, a common consideration for MTB riding. For longer training blocks, prioritize units with longer battery life and accessible charging methods.
Data Quality And Sensor Technology
Look for models with temperature compensation, strain gauge technology, and gyro/accelerometer integration when applicable. Dual-sensing meters provide richer data, including left/right balance and cadence, which can improve training insights. Ensure the device delivers consistent readings across a range of temperatures and terrains typical of mountain biking.
Ecosystem And Data Access
Consider how data integrates with your preferred ecosystem. Garmin-connected meters sync with Garmin watches and Edge devices, while ANT+ and Bluetooth compatibility ensures compatibility with third-party apps and platforms. If you use multiple training services or ride different bikes, a system with easy data export and device syncing will simplify your workflow.
Value And Maintenance
Weigh options by overall value: accuracy, durability, and ease of use against price. Pedal and crank-based meters require different maintenance levels; pedals may need bearing or sensor recalibration over time, while cranksets emphasize crank arm and spider integrity. Regular cleaning and occasional software updates help preserve measurement accuracy and reliability on challenging MTB routes.
