Garmin Rally XC110 Single-Sensing Power Meter Pedals

Mountain bikers and gravel riders seeking reliable power data on technical trails will appreciate the Garmin Rally XC110. This single-sensing power meter pedal measures total power and cadence from the left pedal, then doubles the value to estimate total output, providing a simple and effective way to track performance. The pedal body is built from composite material with a CNC machined hardened steel spindle, ensuring durability for off-road use. It is compatible with Shimano SPD cleats (SM-SH51) and offers a Q-factor of 53 mm (or 55 mm with the included 2 mm washer), allowing for a natural foot position. Installation is straightforward: simply replace your existing pedals, and the automatic calibration ensures accurate readings without manual intervention. With ANT+ and Bluetooth Smart connectivity, the Rally XC110 pairs seamlessly with Garmin Edge cycling computers, compatible smartphones, and popular training apps. The pedal is powered by user-replaceable LR44/SR44 or CR1/3N batteries, delivering up to 120 hours of battery life. It is rated IPX7 for water resistance, so it can withstand rain, mud, and puddles. The field-replaceable spindle design extends the product's lifespan, and software updates are easily managed through the Garmin Connect app. Whether you are training for a cross-country race or exploring remote gravel routes, the Rally XC110 provides the power metrics you need to ride smarter.

Why choose it

The Rally XC110 offers a cost-effective entry into power-based training without compromising on Garmin's renowned quality. Its single-sensing design keeps the price lower while still providing accurate and consistent power data. The durable composite body and IPX7 rating make it suitable for harsh trail conditions, and the long battery life means less frequent replacements. The pedal is easy to install and pairs effortlessly with your existing devices, making it a practical choice for riders who want to add power measurement to their setup.

Ideal use cases

• Mountain bikers looking to monitor training intensity on technical terrain
• Gravel cyclists who want power data for long-distance rides
• Cyclocross racers needing reliable metrics in muddy conditions
• Indoor trainers using compatible apps like Zwift or TrainerRoad
• Riders who prefer SPD cleats for walkability and off-bike comfort

Good to know

The Rally XC110 measures power only from the left pedal, so if you have a significant left/right power imbalance, the total power estimate may be less accurate. However, for most riders, the single-sensing approach provides consistent and actionable data. The pedal includes a 2 mm washer to adjust Q-factor if needed, and the spindle can be replaced if damaged, reducing long-term costs. Remember to check battery orientation when replacing, and use the Garmin Connect app to update firmware for optimal performance.
