Garmin Rally RS200 Power Meter Pedals - Review

Compatibility

One of the most significant improvements is the Rally RS200's cross-compatibility. These pedals mark a departure from the brand's previous model-specific approach. The ability to switch between different pedal bodies (SPD, SPD-SL, and Look Kéo) without professional assistance is a game-changer, offering unprecedented flexibility for cyclists who use different bikes or engage in multiple cycling disciplines.

Installation

When it comes to installation and calibration, Garmin has made the process more intuitive than ever. The right pedal is installed first by greasing the spindle threads, inserting the spindle into the crank arm, and tightening it with a specific torque. The same steps are followed for the left pedal, which has a reverse thread. The bike chain's position is adjusted, and pedal clearance is checked, with the option to add one washer for increased clearance. 

Accuracy

Accuracy is obviously paramount in power meters, and the Rally RS200 pedals don't disappoint. They offer reliable left/right power data with a minimal margin of error, matching or even exceeding the performance of many high-end power meters. This accuracy, combined with the advanced cycling dynamics when paired with compatible Garmin devices, provides cyclists with an in-depth insight into their performance, helping to optimize training and improve overall technique.

Durability

The durability of the Rally series has also seen enhancements. The pedals are robust, designed to withstand various terrains and weather conditions. The battery life, while not the longest on the market, is adequate for most cyclists' needs, and the use of standard LR44/SR44 batteries eliminates the need for proprietary charging equipment.

Pros:

• Cross-Compatibility: The standout feature of the Rally RS200 is the ability to switch between different pedal bodies (SPD, SPD-SL, and Look Kéo), catering to cyclists involved in multiple disciplines or using different bikes.
• Accurate Power Measurement: With a minimal margin of error at +/- 1%, the pedals provide reliable power data, ensuring precise and dependable performance analytics for serious cyclists.
• Advanced Cycling Dynamics: When paired with compatible Garmin devices, the pedals offer detailed data on cycling dynamics, such as left/right balance and seated vs. standing position, which can greatly aid in training optimization.
• Ease of Installation and Use: The simplified installation process make the RS200 user-friendly, even for those less technically inclined. Note they require a 15mm pedal wrench to install.
• Durable Construction: These pedals are robust and built to endure various cycling conditions and terrains, making them suitable for all types of rides.
• Versatile Connectivity: With support for both ANT+ and Bluetooth, the pedals ensure compatibility with a wide range of devices, including smartphones and high-end cycling computers.
• Battery Life: The battery life of approximately 120 hours is class leading and doesn't require a recharge but a simple coin-battery change. 

Cons:

• High Cost: One of the main drawbacks is the price; the Rally RS200 sits at the higher end of the market, making it an investment primarily suited for pros or serious enthusiasts.
• Weight: At approximately 320 grams, these pedals are slightly heavier than some lightweight pedal options available, which might be a consideration for ultra-performance-focused riders.
• Cleat Compatibility: While the system is designed for Shimano SPD-SL cleats, users must switch the pedal body for use with other systems, which, while doable, is an extra step that requires an additional purchase.
• Garmin Rally pedals require an old-school 15mm pedal wrench to install rather than a standard hex wrench. 
• Rally pedals do have amongst the lowest rider weight limit at 105kg, so keep this in mind
