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. At 300 watts, the reading will be within ±3 watts of true output. This accuracy is consistent across the full Rally range (RS, RK, and XC cleat interfaces) and is maintained across a wide operating temperature range. 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: all Garmin Edge cycling computers (130, 540, 840, 1040, 1050) and Garmin Forerunner/Fenix watches; all Wahoo ELEMNT, BOLT, and ROAM head units via ANT+; Zwift, TrainerRoad, Rouvy, and other training platforms via Bluetooth Smart; third-party head units including Bryton, Polar, Sigma, and Lezyne; and Apple Watch via Bluetooth Smart with supported 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.
What are the differences between the Garmin Rally 110 and Rally 210 power meter pedals?
The core distinction is sensor distribution. The Rally 110 series (RS110, RK110, XC110) houses active strain gauges solely in the left pedal spindle, measuring left-leg force and doubling it to estimate total power — a cost-effective solution that assumes equal bilateral contribution. The Rally 210 series (RS210, RK210, XC210) features active, synchronized sensor spindles in both pedals, enabling true dual-sided measurement with independent left/right power 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.
How does the Garmin Rally 110/210 rechargeable battery system work, and how long does it last?
The Garmin Rally 110 and 210 series use a sealed internal rechargeable lithium-ion battery integrated directly into the steel spindle, eliminating the traditional battery door that was a common entry point for moisture and dirt. Charging is done via two custom magnetic clips that snap onto the contact bands of the pedal axles and connect to a standard USB-C power source. A full charge provides up to 90 hours of active riding time. The sealed design maintains a robust IPX7 waterproof rating.
What is Travel Mode on the Garmin Rally power meter pedals and how do I use it?
Travel Mode is a deep-sleep feature that completely disables the Rally pedals' motion sensors during transit, preventing the highly sensitive internal accelerometers from waking repeatedly when a bike is transported in a vehicle or travel case — which would otherwise drain the battery. 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 provided magnetic charging clips — the detection of external electrical current triggers a hardware reset and re-enables wireless pairing.
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: (1) Left/Right Balance — tracks the percentage of total power generated by each leg, helping identify muscular imbalances for rehab or strength training; (2) Power Phase (PP) — maps the exact pedal stroke angle where positive torque begins and ends, helping coaches analyse stroke efficiency; (3) Platform Centre Offset (PCO) — measures lateral force distribution across the pedal platform in millimetres, where a high value indicates incorrect cleat alignment; (4) Seated vs. Standing Position — detects rider position by analysing the physical force signature on the spindle. These metrics are available on compatible Garmin cycling computers and head units.
What is Force Data on the Garmin Rally power meter, and how is it different from standard power measurement?
Force Data measures the absolute physical pressure applied to the pedal platforms in Newtons (N), providing a deeper layer of performance analysis beyond standard power and cadence metrics. While power (watts) and cadence (RPM) are used for pacing, Force Data isolates the actual muscular effort required to turn the cranks. For example, generating 300W at 60 RPM demands significantly higher muscular force than generating 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 variables such as crank arm length differences, enabling accurate cross-bike output comparisons.
How do I pair the Garmin Rally 110 or 210 power meter pedals to my cycling computer or head unit?
The Garmin Rally 110 and 210 series support both ANT+ and Bluetooth Smart protocols. For secure pairing (recommended to prevent cross-pairing in crowded race environments): remove the left pedal, rotate it to wake the sensors and confirm via the status LED, then hold it horizontal for 2 seconds → rotate 90° with threaded end pointing up and hold 2 seconds → rotate another 90° with threaded end pointing sideways and hold 2 seconds until the LED flashes white → rotate 90° with threaded end pointing down, hold 2 seconds, then return to horizontal. When the LED flashes green, secure pairing mode is active — add the device via the Garmin Connect app. For older head units or third-party devices, open the Garmin Connect app → Rally settings → Connection Type → enable 'Allow Open Connections'.
How does the Garmin Rally 210 compare to the Favero Assioma PRO power meter pedals?
Both are premium dual-sided pedal-based power meters rated at ±1% accuracy, but they differ across key parameters. The Favero Assioma PRO RS-2 weighs 247g per pair vs. the Rally 210's 312g (saving 65g of rotational mass), has a lower stack height of 10.5mm vs. 12.2mm, offers up to 160 hours of battery life vs. 90 hours, and carries an IP67 rating vs. Garmin's IPX7. In Singapore, the Assioma PRO dual-sided models (RS-2, RL-2, MX-2) retail at SGD 899 each (RL-2 on promotion — check listing for latest price), vs. the Rally RS210 at SGD 1,529. The Rally 210 has advantages in Garmin ecosystem integration, Pedal IQ auto-calibration, and cleat body modularity (RS/RK/XC swap). Bikers.SG is an authorized reseller of both brands in Singapore.
