Garmin Rally XC110: Single-Sensing Pedal Power Meter
The Garmin Rally XC110 uses a single-sensing power meter built into a pedal body. It is designed for off-road use with SHIMANO SPD cleats and offers easy transfer between bikes by removing the power sensor from one pedal and attaching to another. It tracks total power and cadence with a responsive sensor suite including a new strain gauge and gyroscope. Accuracy is stated as within ±1% under typical riding conditions. Best for riders who want quick swaps between mountain and gravel bikes without re-calibrating extensively.
Who this is for: mountain bikers or gravel riders who switch bikes often and value fast setup. Why selected: strong transferability and solid accuracy with modern sensor technology.
Caution: While transferable, setup requires ensuring proper alignment and cleat compatibility on each bike. Some users may prefer dual-sensing systems for even more data on both legs.
Favero Assioma PRO RS-1: Single-Side Power Meter Pedals
The Assioma PRO RS-1 features a left-pedal power sensor with the right pedal free of sensing. It supports full Shimano SPD-SL cleat compatibility, making it a viable option for road riders who want precise left-leg power data with a lighter sensor burden. Best for riders who want pro-grade metrics from a single-sensing design and straightforward installation. Why selected: proven left-pedal measurement with reliable data flow and configurable cleat compatibility.
Caution: This model is single-sensing, so you won’t get built-in power data from the right leg unless you upgrade to a full dual-sensing pair.
Favero Assioma Uno Power Meter Pedal
The Assioma Uno provides a straightforward introduction to power meters with a left-pedal sensor design. It emphasizes easy installation and long battery life, delivering up to approximately 50 hours per charge depending on use. This option is best for riders who value simple functionality and reliable data from a single side. Why selected: dependable single-sensor setup with modern cycling tech and rechargeable power.
Caution: Data reflects single-sided measurement; athletes seeking full left-right balance may prefer a dual-sensing setup.
ZHURUI PR10-E US15A Power Meter Plug/Home Meter
The ZHURUI PR10-E is a more entry-level option focused on home or shop use. It features a 2.4-inch color TFT display with multiple pages that show overview, one-shot electrical metrics, and real-time parameters. Best for enthusiasts who want a clear, home-oriented power readout and simple alarm features for monitoring thresholds. Why selected: practical display and alarm functions for basic power tracking in a stationary setup.
Caution: Not a pedal-based or bike-mounted solution; intended for power measurement in electrical circuits and home use rather than dedicated cycling power data on the bike.
Favero Assioma PRO MX-1: Single-Sided Power Meter Pedals
The Assioma PRO MX-1 provides single-sided power measurement with a dedicated left-pedal sensor and the right pedal without a sensor. Known for reliable and accurate power data in varied riding conditions, MX-1 targets riders who want pro-grade metrics without full dual-sensing complexity. Battery life and sensor robustness support long rides. Why selected: strong reliability in real-world riding with a focus on left-side data and easy transferability.
Caution: As a single-sider, you won’t capture right-side power; consider this when training plans rely on bilateral balance data.
Buying Guide
What should you consider before buying a single-sided power meter?
Compatibility with your pedals and cleats is essential. Confirm cleat type (Shimano SPD, SPD-SL, Look Keo) and whether you need full pedal replacement or a sensor that transfers between bikes. Battery life determines how often you’ll recharge during multi-day rides or training blocks.
How important is data detail and potential upgrade paths?
Single-sided meters provide useful metrics like power and cadence, but bilateral balance data requires dual-sensing systems. If you plan to upgrade later, choose models that allow converting to dual-sensing without replacing pedals.
Transferability and installation ease
For riders who switch bikes frequently, pedal-based meters with simple sensor transfer save time. Check how easy it is to move sensors between bikes and whether clips, spindles, or spare cleats are included.
Performance in different conditions
Weather, terrain, and ride duration affect battery life and data stability. Seek units with robust seals, reliable sensors, and clear data readouts during outdoor rides.
Data access and ecosystem
Most options integrate with bike computers and mobile apps. Consider whether you prefer Garmin, Favero, or third-party platforms for your training analytics and route planning.
FAQ
- What is a single-sided power meter?
- Can I switch a single-sided power meter between bikes?
- Will a single-sided meter show my bilateral balance?
- Which is best for road vs. off-road riders?
- How long do batteries last on these meters?
- Is there a risk of calibration hassle?
A single-sided power meter measures power on one pedal (usually the left) and provides insights into your pedaling force and efficiency. It’s typically more affordable and lighter than dual-sensing systems.
Yes, most single-sided pedal meters are designed to transfer between bikes. Ensure you follow the manufacturer’s installation steps for proper sensor alignment and cleat compatibility.
No. Bilateral balance data requires a dual-sensing setup. A single-sided meter provides useful data, but it does not capture right-side power by default.
For road cyclists, models with SPD-SL or Look Keo compatibility and easy transfer are advantageous. For off-road, pedal durability and compatibility with SPD cleats are critical.
Battery life varies by model and usage. Many provide around 50 hours or more per charge under typical training use; some offer up to 160 hours depending on settings and sensor activity.
Many modern units are designed for plug-and-play operation with minimal calibration. Some models still require occasional calibration or spindles checks, especially after swapping bikes.
