These updates mean that both brands now cover the main road cleat ecosystems and offer rechargeable batteries, narrowing the gap for many buyers.

Cleat compatibility: Look Keo vs Shimano SPD-SL ecosystems

Cleat compatibility is a critical decision point. Switching pedal systems often means changing shoes or at least swapping cleats—a hassle for many riders. Here’s how the current models line up:

Key points:

• If you ride Shimano SPD-SL, both Favero (DUO-Shi&tag=rydecruzamz-20), PRO RS-2) and Garmin (Rally RS) offer direct options.
• Look Keo users can choose Assioma UNO/DUO or Garmin Rally RK.
• Garmin’s modular pedal body design allows swapping between road and MTB platforms, but cleat compatibility is always model-specific.

Battery life and charging: How do they compare?

Battery life and charging convenience are major usability factors, especially for riders who log high weekly hours or travel frequently. Here’s how the latest models stack up:

(Favero PRO RS-2 product page, Garmin Rally RS210 review)

Caveats:

• These are manufacturer claims, not independent test results. Real-world battery life varies with temperature, transmission mode, and battery age.
• Favero’s magnetic charging cable is robust and easy to use, minimizing port wear and water ingress risk.
• Garmin’s proprietary dock is secure but less universal than USB-C.

Power measurement: Single-sided vs dual-sided, claimed accuracy

Both brands offer single-sided and dual-sided models, but the implications for accuracy and data depth are nuanced.

\*Garmin Cycling Dynamics includes platform center offset, seated/standing time, and more, but is best supported on Garmin head units (Garmin Rally RS210 review, Favero Assioma product range).

Important distinctions:

• Dual-sided models measure each leg independently, providing more accurate left/right balance than single-sided systems, which estimate total power by doubling one side.
• Both brands claim ±1% accuracy, but this is a manufacturer specification, not an independently verified field result (Favero PRO RS-2 product page, Garmin Rally RS210 review).
• No available source establishes that one brand is more accurate than the other in real-world riding.

Connectivity and ecosystem integration

Both Favero and Garmin support ANT+ and Bluetooth transmission, making them compatible with a wide range of bike computers, smart trainers, and training apps. However, there are differences in advanced data and ecosystem integration:

• Garmin Rally: Delivers full Cycling Dynamics metrics (platform center offset, seated/standing time, power phase, etc.) when paired with Garmin Edge computers or watches. Basic power and cadence are available to any ANT+ or Bluetooth device, but advanced metrics may not display on non-Garmin head units (Garmin Rally RS210 review, Planetatriatlon comparison).
• Favero Assioma: Transmits power and cadence universally, with additional pedal efficiency and angle metrics available via the Favero app and some third-party platforms. The data set is not as deep as Garmin’s Cycling Dynamics, but the essentials are present for most users (Favero Assioma product range).

Both work with Wahoo, Hammerhead, and other computers for core data. If you want the deepest pedal analytics and already use Garmin devices, Rally has the edge. For most riders, both provide all the essential metrics.

Transferability and service: Moving pedals and maintaining them

How easily can you move your power meter between bikes, or service it if something goes wrong? Here’s how the systems differ:

• Garmin Rally: The measurement spindle can be swapped between compatible pedal bodies (RS, RK, XC), letting you move your power meter between road and MTB setups without buying a second system (Garmin Rally launch article). This modularity is unique to Garmin and a major advantage for multi-bike or mixed-surface riders.
• Favero Assioma: The entire pedal must be moved as a unit. There is no official system for swapping just the spindle between different pedal bodies or cleat standards. However, installation is straightforward and only requires an 8mm hex key (Favero Assioma product range).
• Service and battery replacement: Both brands use rechargeable batteries. The available sources do not confirm universal user-replaceable batteries or detailed service procedures—check with the manufacturer for your specific model and region.

Price, weight, and value for money

Pricing and weight can tip the balance for many buyers, but published figures vary and should be treated as indicative only. Always check current regional pricing and specifications.

\*Weight figures for Rally RS210 and RK210 vary by source; 312 g is the most consistently cited for road models (Garmin Rally RS210 review), but some sources report higher numbers that may reflect MTB models or include cleats.

Value notes:

• Favero typically undercuts Garmin on price, especially for dual-sided models.
• Weight differences are modest for road models, but Favero’s PRO RS-2 is notably light for a dual-sided power pedal.
• Price varies by country, retailer, and promotions.
