Garmin Rally 210/110 Review: Power Meter Pedals in 2026

What it is

The Garmin Rally 210 and 110 are power meter pedals aimed at serious cyclists who want accurate watt data without bolting an external pod to their crank arm. The Rally 110 covers single-sided measurement, while the 210 goes dual-sided for full left/right power balance. These sit firmly in the premium tier of the pedal-based power meter market, competing directly with Favero's Assioma lineup. If you want clean integration with Garmin's ecosystem and hate fussing with AA batteries, this generation delivers with internal rechargeable cells and a universal spindle that works across multiple cleat systems.

Key specs

• Accuracy: +/- 1%
• Battery: Internal rechargeable, rated at 90 hours
• Design: Universal spindle, compatible with multiple cleat standards
• New features: Force metrics, Pedal IQ calibration system
• Connectivity: ANT+ and Bluetooth to head units and cycling computers

Note: The Rally pedals are pure cycling power measurement devices. There is no GPS chipset, heart rate sensor, SpO2, skin temperature, altimeter, or display built in. They transmit power, cadence, and advanced metrics to your head unit. Keep that in mind if you landed here expecting a wearable tracker.

Performance in the real world

The 1% accuracy claim puts the Rally 210/110 in the same bracket as strain-gauge-based competitors, and in real-world use that figure holds up reasonably well for structured intervals and FTP testing. The Pedal IQ calibration system is a genuine improvement over previous generations, reducing the fiddly manual zero-offset routine that annoyed Rally users for years. You still want to do a static calibration before a key session, but the system is more intuitive now.

The Force metrics addition gives you data beyond raw watts, including total force applied to the pedal and the angle at which peak force occurs through the pedal stroke. For coaches working with riders on pedaling efficiency, this is useful information. For most recreational riders, it is extra noise unless you have the coaching context to act on it.

The 90-hour battery life on internal rechargeables was a strong selling point when these pedals launched. Charging via USB rather than hunting for coin cells or AA batteries is a real quality-of-life upgrade. That said, Favero has reportedly pushed firmware updates to its Assioma Pro RS and Pro MX pedals that significantly extended battery life beyond the Rally's 90-hour figure. If that gap is as large as claimed, it matters for bikepacking, ultra-endurance events, or riders who simply hate charging gear frequently. Worth verifying the latest Favero specs before buying.

The universal spindle design is a practical win. Previous Rally generations required you to commit to a cleat standard at purchase. Now you can swap between Look Keo and SPD-SL compatible bodies without buying entirely new pedals. For riders who switch between bikes or travel with rental shoes, that flexibility has real value.

Garmin ecosystem integration is tight, as you would expect. Pairing with an Edge head unit is seamless, and metrics feed cleanly into Garmin Connect and Training Peaks. If you are already invested in Garmin hardware, the Rally fits without friction. If you are on Wahoo or running a mixed-brand setup, the ANT+ and Bluetooth dual transmission means compatibility is not actually an issue in practice.

Who it's for / who should skip it

The Rally 210/110 makes most sense for riders who are already deep in the Garmin ecosystem and want pedal-based power with dual-sided measurement and advanced force data. Triathletes who swap between a road bike and a TT bike will appreciate the universal spindle. Coaches who use Force metrics for pedaling analysis have a reason to choose Rally over alternatives.

Skip it if battery life is your primary concern. Favero's Assioma Pro RS is worth a direct comparison on battery specs before you commit, and it costs less. If you are a solo rider doing mostly day rides or standard training blocks, 90 hours is perfectly adequate, but for multi-day touring or endurance racing you should check the current Favero figures before assuming Rally wins on any front. Also skip it if you are not already on Garmin hardware and do not care about Force metrics, because the Favero offers comparable accuracy at a lower price point.

Verdict

The Garmin Rally 210/110 is a well-built, accurate power meter pedal with genuine improvements in battery design and calibration. It remains a strong choice for Garmin loyalists and coaches who want Force metrics. The competition from Favero on battery life and price is real though, so do a side-by-side spec check at the time you buy rather than assuming the Rally leads on either of those fronts.
