Garmin Rally™ RK110 Single-Sensing Power Meter Pedals for Cycling Performance

The Garmin Rally RK110 is a single-sensing power meter pedal system for road cyclists using Look KEO cleats, delivering ±1% power accuracy from a rechargeable, transferable sensor that fits into standard Rally pedal bodies. It's the Look KEO equivalent of the Rally RS110 (Shimano SPD-SL), sharing the same core technology and upgrade path but designed for riders already committed to the Look KEO cleat system.

The power sensor uses a reimagined strain gauge with an integrated gyroscope for accurate power and cadence measurement. Single-sensing measures power from the left pedal and doubles it to estimate total power — accurate enough for the vast majority of training and racing purposes, and upgradeable to full dual-sensing by adding the right-side sensor separately. The rechargeable battery delivers up to 90 hours of ride time, with a 15-minute quick charge providing up to 12 hours of riding. The Pedal IQ™ smart calibration system monitors conditions such as temperature changes and alerts you when recalibration is needed, keeping your data consistently accurate without manual guesswork. The carbon pedal body is lightweight and durable.

The transferable sensor design is a key Rally advantage: the power meter pod moves between compatible Rally 110 or 210 pedal bodies, so you can run the same sensor across multiple bikes without buying a new power meter for each. 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 use Shimano SPD-SL cleats, the Rally RS110 is the equivalent model. If you need dual-sensing from the outset for independent left/right power balance, the RK110 can be upgraded by purchasing the right-side sensor separately.

What It's Good For

• Road cyclists wanting accurate power data (±1%) with Look KEO 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 Shimano SPD-SL cleats — the Rally RS110 is the correct model for SPD-SL
• Riders who specifically need independent left/right power balance from the outset — the RK110 is single-sensing; dual-sensing requires the additional right sensor
• Non-clipless pedal users — the Rally system is designed for clipless use only
• Casual cyclists who don't need detailed power metrics or training data

Frequently Asked Questions

What is the difference between the RK110 and the RS110?
The RK110 and RS110 share identical technology and features. The only difference is cleat compatibility: the RK110 is for Look KEO cleats, while the RS110 is for Shimano SPD-SL cleats. Choose based on whichever cleat system you currently use.

What is the difference between single-sensing and dual-sensing?
Single-sensing (RK110) 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 is more than sufficient. The RK110 can be upgraded to dual-sensing by purchasing the right-side sensor separately.

Can I transfer the sensor between bikes?
Yes — the Rally RK110 sensor pod is removable and can be transferred between compatible Rally 110 or 210 pedal bodies, allowing you to use the same power meter on multiple bikes by purchasing additional pedal bodies separately.

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 monitors battery level and alerts you when it's running low.
