GARMIN Rally RS/XC210 Dual-Sensing Power Meter Pedal Bundle (SPD-SL, ANT+/BLE)

Precision power measurement is no longer a luxury reserved for the lab. The GARMIN Rally RS/XC210 dual-sensing power meter bundle delivers laboratory-grade accuracy (±1.0%) directly to your pedals, enabling you to track left/right balance, pedaling dynamics, and torque with every revolution. Whether you're a road racer chasing marginal gains or a gravel enthusiast tackling technical climbs, this system provides the data you need to train smarter and ride stronger.

Why choose it

Dual-sensing technology is the cornerstone of this system. Unlike single-sided meters, it captures independent data from both legs, revealing asymmetries that could hinder your performance. The robust construction—stainless steel spindle, composite body, and IPX7 waterproofing—ensures reliable operation in all weather conditions, from torrential downpours to dusty gravel. With up to 120 hours of battery life, you can train for weeks without worrying about charging.

Ideal use cases

• Road cyclists who demand precise power data for structured training and racing
• Gravel and cyclocross riders who need durability and accuracy in challenging conditions
• Triathletes monitoring pedal efficiency over long distances
• Coaches and athletes analyzing pedaling dynamics to optimize performance

Good to know

This bundle includes both the RS (road) and XC210 (cross-country) pedal bodies, giving you two systems in one. The included SPD-SL cleats are perfect for road use, but you can easily switch to SPD cleats for off-road adventures. The pedals are compatible with most standard cranksets, and installation is straightforward with the included tools. Field calibration ensures your data remains accurate even after long rides.

Pro tip: Regularly check the battery level via your Garmin device or smartphone app, and keep spare LR44/SR44 batteries on hand for long tours. The 2 mm spacer is ideal for riders who prefer a wider stance—test both configurations to find your optimal Q-factor.
