Garmin Rally™ RS110 Single-Sensing Power Meter Pedals for Cycling Performance

The Garmin Rally RS110 is a single-sensing power meter pedal system for road cyclists using Shimano SPD-SL cleats, delivering ±1% power accuracy from a rechargeable, transferable sensor that fits into standard Rally pedal bodies. It's the entry point into Garmin's Rally power meter ecosystem — measuring power from the left pedal and doubling the reading to estimate total power — with a clear upgrade path to full dual-sensing if you want independent left/right power data in the future.

The power sensor uses a reimagined strain gauge with an added gyroscope for improved accuracy and cadence measurement. The rechargeable battery delivers up to 90 hours of ride time, and a quick 15-minute charge provides up to 12 hours of riding — so even if you forget to charge before a ride, a short top-up gets you back out quickly. The Pedal IQ™ smart calibration feature monitors conditions such as temperature changes and alerts you when calibration is needed, removing the guesswork from maintaining accurate data. The carbon construction keeps the pedal body lightweight without sacrificing durability.

A key advantage of the Rally system is the transferable sensor design: the power meter pod can be moved between compatible Rally 110 or 210 pedal bodies, meaning you can run the same sensor across multiple bikes or switch between road and off-road pedal bodies without buying a new power meter. When paired with a compatible Garmin Edge computer — such as the Edge 540, Edge 840, Edge 850, Edge 1040, or Edge 1050 — power and cadence data are displayed in real time.

If you're deciding between the RS110 (single-sensing) and a dual-sensing system, single-sensing measures left leg power and doubles it to estimate total power — accurate enough for the vast majority of training and racing purposes. Dual-sensing measures each leg independently, providing left/right balance data. The RS110 can be upgraded to dual-sensing by purchasing the additional right-side sensor separately.

What It's Good For

• Road cyclists wanting accurate power data (±1%) with Shimano SPD-SL cleats
• Transferable sensor: move the power meter between compatible Rally 110 or 210 pedal bodies across multiple bikes
• 90-hour rechargeable battery with 15-minute quick charge for 12 hours of riding
• Pedal IQ™ smart calibration alerts for consistently accurate power data
• Clear upgrade path to dual-sensing (independent left/right power) by adding the right-side sensor separately
• Lightweight carbon pedal body construction
• Seamless integration with Garmin Edge computers for real-time power and cadence display

What It's NOT Good For

• Cyclists using Look KEO or Shimano SPD (MTB) cleats — the RS110 is SPD-SL specific; other Rally models cover different cleat systems
• Riders who specifically need independent left/right power balance from the outset — the RS110 is single-sensing; dual-sensing requires the additional right sensor
• Non-clipless pedal users — the Rally system is designed for clipless use only

Frequently Asked Questions

What is the difference between single-sensing and dual-sensing?
Single-sensing (RS110) measures power from the left pedal and doubles it to calculate total power. Dual-sensing measures each pedal independently, providing true left/right power balance data. For most training and racing purposes, single-sensing accuracy is more than sufficient. The RS110 can be upgraded to dual-sensing by purchasing the right-side sensor separately.

Can I transfer the sensor between bikes?
Yes — the Rally RS110 sensor pod is removable and can be transferred between compatible Rally 110 or 210 pedal bodies. This means you can use the same power meter on multiple bikes by purchasing additional pedal bodies separately, rather than buying a complete new power meter for each bike.

How long does the battery last and how do I charge it?
The rechargeable battery provides up to 90 hours of ride time. A 15-minute quick charge delivers up to 12 hours of riding, and a full charge takes approximately 2 hours. The Pedal IQ™ system also monitors battery level and alerts you when it's running low.

Which Garmin Edge computers is it compatible with?
The Rally RS110 is compatible with all ANT+ and Bluetooth-enabled Garmin Edge computers, including the Edge 540, Edge 840, Edge 850, Edge 1040, and Edge 1050. It is also compatible with any ANT+ head unit from other manufacturers.
