Garmin Rally 110 & 210: The Rechargeable, Transferable Power Meter for Every Bike

For years, cyclists who ride across multiple disciplines—road, gravel, and mountain—have faced a costly dilemma: invest in separate power meters for each bike or accept inconsistent training data. Garmin's latest announcement, made on September 9th, aims to solve that problem for good with the launch of the next-generation Rally™ 110 and 210 pedal-based power meters.

This new ecosystem is built on a foundation of unprecedented versatility, convenience, and accuracy, designed to give athletes a single, reliable power solution no matter where they ride. The headline feature is a rechargeable, transferable power sensor that can be easily swapped between different pedal bodies, finally delivering on the promise of a truly universal power meter.

Susan Lyman, Garmin Vice President of Consumer Sales and Marketing, highlights this multi-terrain focus: “From paved paths to gravel roads to mountain trails, cyclists everywhere are training hard, and they need accurate data to help them reach their goals. The next-gen Rally 110 and 210 power meters offer that accurate and reliable data Garmin is known for, along with unbeatable versatility, durability, battery life and more advanced features than ever before.”

Let’s dive into what makes the new Rally system a potential game-changer.

The Core Innovations: Rechargeable, Transferable, and Smarter Than Ever

Garmin has addressed several key pain points of previous power meter generations with a host of user-focused upgrades.

• A Rechargeable Powerhouse: Gone are the days of swapping tiny coin-cell batteries. The Rally pedals feature an internal rechargeable battery offering a massive up to 90 hours of ride time. For those in a pinch, a quick 15-minute charge provides up to 12 hours of use. A new "Travel Mode" also allows the pedals to be put to sleep, conserving battery during transport.
• The Transferable Spindle System: At the heart of the Rally ecosystem is a removable power sensor, or spindle, that can be quickly moved between different pedal bodies using common tools. This allows a rider to use the same power meter on their road bike with SHIMANO SPD-SL cleats, their gravel bike with SHIMANO SPD cleats, and back again with minimal fuss.
• Pedal IQ™ Smart Calibration: To ensure data integrity, the Rally system introduces smart calibration alerts. The pedals monitor factors like temperature changes and time since the last calibration, notifying the rider when a quick recalibration is recommended for maintaining peak accuracy.
• Responsive and Accurate Data: A completely redesigned sensing spindle enhances responsiveness and delivers power data with an impressive ±1% accuracy. The system is also fully compatible with oval chainrings, ensuring precise measurement regardless of your component choice.
• Discipline-Specific Durability: Garmin has engineered the pedal bodies for their intended use. The RS (SHIMANO SPD-SL) and RK (LOOK KEO) road pedals feature a new, lightweight carbon polymer design, while the XC off-road pedals have a durable all-metal build and a lower stack height for better clearance over rocks and roots.

Rally 110 vs. 210: Choosing Your Path to Power

Garmin offers two distinct tiers to suit different needs and budgets, with a clear upgrade path.

• Rally 110 (from $749.99): This is the single-sensing system, measuring power produced by your left leg and doubling it to estimate total power. It provides essential metrics like power and cadence, making it an excellent entry point for athletes new to power-based training.
• Rally 210 (from $1,199.99): The dual-sensing system measures power from each leg independently. This unlocks Garmin’s advanced Cycling Dynamics, providing deeper insights like left/right balance, seated vs. standing time, power phase, and platform center offset. This data is invaluable for identifying and correcting muscular imbalances and perfecting pedal stroke efficiency.

Crucially, riders who start with the Rally 110 can purchase an upgrade pedal at a later date to convert their system to a full dual-sensing Rally 210.

The Takeaway

The Garmin Rally 110 and 210 aren't just an incremental update; they represent a fundamental rethinking of the power meter ecosystem. By focusing on versatility with the transferable spindle and solving major user frustrations with a rechargeable battery and smart calibration, Garmin has created a compelling solution for the modern, multi-discipline cyclist.

Whether you're a road racer looking to analyze every watt or a gravel adventurer wanting consistent data across all your bikes, the new Rally system offers a powerful, flexible, and reliable training partner.

The Rally power meters are available now, with bundles combining road and off-road pedal bodies starting at $1,449.99. To learn more, visit the official Garmin website.
