Architectural Evolution and Technical Specifications

The Rally x10 platform (encompassing the 110 and 210 models) focuses on modularity, mechanical resilience, and advanced kinematic tracking. The series comprises three distinct cleat interfaces: the "RS" series for Shimano SPD-SL road cleats, the "RK" series for Look Keo road cleats, and the "XC" series for Shimano SPD off-road cleats.

Comparative Hardware Generations & Competitor Integration

The following table compares the Rally 110/210 series with its predecessors and the Favero Assioma PRO standard.

While Garmin's transition to an integrated rechargeable battery is a major durability leap, the Favero Assioma PRO series holds a commanding lead in physical efficiency — shaving up to 65 g of rotational weight off a road setup and 53 g off an off-road setup. A stack height of just 10.5 mm on the Assioma PRO RS also places the foot closer to the spindle centre than Garmin's 12.2 mm road profile, optimizing biomechanical leverage and pedaling efficiency.

Technical and Operational Frequently Asked Questions

What is the measurement accuracy of the Garmin Rally 110 and 210 power meters?

The Garmin Rally 110 and 210 series are rated at ±1% accuracy — the industry benchmark for professional-grade power meters. This means that at 300 watts, the reading will be within ±3 watts of true output. This accuracy level is consistent across the full Rally range regardless of cleat interface (RS, RK, or XC) and is maintained across a wide operating temperature range. For reference, the Favero Assioma PRO series is also rated at ±1% accuracy, placing both systems on equal footing for competitive and training use.

What devices are compatible with the Garmin Rally 110 and 210 power meter pedals?

The Rally 110 and 210 series transmit over both ANT+ and Bluetooth Smart, making them compatible with a very wide range of devices:

• Garmin cycling computers: Full compatibility with all Garmin Edge series (Edge 130, 540, 840, 1040, 1050) and Garmin Forerunner/Fenix watches with power meter support.
• Wahoo: Compatible with all Wahoo ELEMNT, BOLT, and ROAM head units via ANT+.
• Zwift & training apps: Compatible with Zwift, TrainerRoad, Rouvy, and other platforms via Bluetooth Smart on iOS, Android, macOS, and PC.
• Third-party head units: Compatible with any ANT+ or Bluetooth Smart-enabled cycling computer, including Bryton, Polar, Sigma, and Lezyne devices.
• Apple Watch: Compatible via Bluetooth Smart with supported cycling apps.

Note: Advanced Garmin Cycling Dynamics metrics (Power Phase, PCO, Seated/Standing) are only displayed on compatible Garmin head units and the Garmin Connect app. Basic power, cadence, and left/right balance are available on all ANT+/Bluetooth devices.

What are the mechanical and telemetry differences between the Rally 110 and Rally 210 series?

The core distinction lies in sensor distribution across the pedal spindles. The Rally 110 models (RS110, RK110, XC110) house active strain gauges solely in the left pedal spindle, measuring left-leg force and doubling it to calculate total wattage. While cost-effective, this assumes equal muscular contribution from both legs — which can introduce inaccuracies for athletes with unilateral strength imbalances.

The Rally 210 models (RS210, RK210, XC210) feature active, synchronized sensor spindles in both pedals, enabling true dual-sided measurement with independent left/right balance, power phase, platform centre offset, and seated vs. standing time.

Riders who start with a 110 model can upgrade to dual-sided by purchasing a standalone right-side upgrade axle and pairing it via the Garmin Connect app. Cyclists seeking a lighter-weight dual-sided alternative may also consider the Favero Assioma PRO RS-2, which delivers complete bilateral accuracy with significantly less bulk.

How does the Garmin Rally rechargeable battery system work, and what are the charging requirements?

The Rally 110 and 210 series use a sealed internal rechargeable lithium-ion battery integrated directly into the steel spindle, eliminating the traditional battery door — a common entry point for moisture and dirt. The sealed design maintains a robust IPX7 waterproof rating.

Charging uses two custom magnetic clips that snap onto the contact bands of the pedal axles, connecting to a standard USB-C power source. Two cables are included in the box for dual-sided models. A full charge provides up to 90 hours of active riding time.

For battery longevity on long-distance rides, the Favero Assioma PRO series offers up to 160 hours continuous run-time following its February 2026 firmware update — nearly double the Rally's capacity on a single charge, with no reduction in signal strength.

What is Travel Mode on the Garmin Rally, and how is it activated and deactivated?

Travel Mode puts the Rally pedals into a deep sleep, completely disabling the internal accelerometers so they do not wake repeatedly during transit — which would otherwise drain the battery when transporting a bike in a vehicle or travel case.

To activate: Open the Garmin Connect app → Garmin Devices → Rally 110/210 → Travel Mode → Enable Travel Mode. The pedals immediately shut down and become unresponsive to physical movement.

To deactivate: Connect the pedals to an active USB power source using the magnetic charging clips. The detection of external electrical current triggers a hardware reset, waking the microcontrollers and re-enabling wireless pairing.

(Note: Favero Assioma PRO pedals feature smart standby modes managed through the Favero App, preventing wake-up from transit vibrations without requiring a hardware plug-in reset.)

What biomechanical metrics does Garmin Cycling Dynamics provide on the Rally 210 dual-sided models?

Garmin Cycling Dynamics on the Rally 210 series provides four advanced training metrics:

• Left/Right Balance: Tracks the percentage of total power generated by each leg, helping identify muscular imbalances for rehab or strength training.
• Power Phase (PP): Maps the exact pedal stroke angle where positive torque begins and ends, helping coaches analyse stroke efficiency.
• Platform Centre Offset (PCO): Measures lateral force distribution across the pedal platform in millimetres. A high PCO value indicates incorrect cleat alignment.
• Seated vs. Standing Position: Detects rider position by analysing the physical force signature on the spindle.

The Favero Assioma PRO series also supports equivalent Cycling Dynamics metrics — including Left/Right Balance, Power Phase, PCO, Torque Effectiveness, and Pedal Smoothness — transmitted seamlessly over ANT+ and Bluetooth.

What is Force Data on the Garmin Rally, and how does it differ from standard power measurement?

Force Data measures the absolute physical pressure applied to the pedal platforms in Newtons (N), isolating the actual muscular effort required to turn the cranks — beyond what standard power and cadence metrics reveal. For example, generating 300W at 60 RPM demands significantly higher muscular force than 300W at 100 RPM, which shifts the load to the cardiovascular system. By measuring force directly at the pedal platform rather than calculating rotational torque at the crank arm, the system also neutralises crank arm length variables, enabling accurate cross-bike output comparisons. Both Garmin and Favero Assioma PRO support direct force measurement.

How do I pair the Garmin Rally 110 or 210 to my cycling computer or head unit?

The Rally series supports both ANT+ and Bluetooth Smart. For secure pairing (recommended in crowded race environments to prevent cross-pairing): remove the left pedal, rotate to wake sensors and confirm via the status LED → hold horizontal for 2 seconds → rotate 90° threaded end up, hold 2 seconds → rotate 90° threaded end sideways, hold 2 seconds until LED flashes white → rotate 90° threaded end down, hold 2 seconds → return to horizontal. When the LED flashes green, add the device via the Garmin Connect app.

For open connections (older or third-party head units): wake the pedals → Garmin Connect app → Rally settings → Connection Type → Allow Open Connections.

(Favero Assioma PRO pedals pair via a single-touch process through the Favero App, automatically handling dual-channel Bluetooth and ANT+ pairing on any head unit, watch, or Zwift setup.)

Head-to-Head Comparison: Garmin Rally 210 vs. Favero Assioma PRO

For riders optimising their performance, the choice between the Garmin Rally 210 and the Favero Assioma PRO is one of the most significant decisions in cycling gear. The physical, electrical, and commercial differences are compared below.

When the Garmin Rally is the Right Choice

The Garmin Rally 210 series is the stronger choice in these specific scenarios:

• Deep Garmin ecosystem integration: If you ride with a Garmin Edge head unit, the Rally unlocks the full Garmin Cycling Dynamics suite natively, with no third-party app required. Metrics sync directly to Garmin Connect and Training Peaks.
• Pedal IQ auto-calibration: The Rally's Pedal IQ feature provides real-time temperature and torque alerts, automatically prompting recalibration when conditions change — a meaningful advantage for riders who race in variable weather.
• Cleat system flexibility: The Rally's modular spindle design allows you to swap the same power sensor between RS (Shimano SPD-SL), RK (Look Keo), and XC (Shimano SPD) pedal bodies — ideal for riders who use different bikes with different cleat standards.
• Look Keo cleat users: The Rally RK210 is one of the only dual-sided power meter pedals available for Look Keo cleats. Favero's Assioma PRO MX covers SPD, but there is no Favero equivalent for Look Keo.

When the Favero Assioma PRO is the Right Choice

The Favero Assioma PRO series is the stronger choice when:

• Battery life is critical: 160 hours vs. 90 hours is a decisive advantage for bikepackers, ultra-endurance racers, and riders who charge infrequently.
• Weight matters: Saving 65 g of rotational mass on a road setup has a measurable impact on acceleration and climbing efficiency.
• Budget is a priority: At SGD 899 for dual-sided models (with the RL series at an even lower promotional price), the Assioma PRO series offers exceptional value vs. the Rally 210 from SGD 1,529.
• Simplicity of setup: One-touch pairing via the Favero App is significantly faster than the Rally's physical secure-pairing sequence.
