Garmin Rally XC200 Power Meter Pedals Review 2026: SPD Power Tested
Overview
Garmin’s Rally range puts a dual-sided power meter directly in the pedal axle, and the XC200 is the SPD (mountain-bike cleat) version — useful for triathletes who train on an indoor bike or gravel bike with SPD cleats and want the same power data across every bike, without needing separate cleats for different pedal systems.
Key Specs
- Cleat system — Shimano SPD, dual-sided
- Accuracy — claimed ±1%; independent testing against a Wahoo KICKR V6 found readings within a watt across the power curve
- Weight — 444g for the pair
- Battery — non-rechargeable LR44/SR44 coin cells, up to 120 hours claimed riding time, swapped with a 4mm hex key
- Stack height — 13.7mm, with adjustable 53–55mm Q-factor via included washers
- Water resistance — IPX7 rated
What Sets Rally Apart
The power meter hardware lives in the pedal axle, which is identical across the whole Rally range — Garmin says the pedal body itself can be swapped between SPD, SPD-SL and Look-compatible versions in under five minutes. That’s a genuine advantage if you own more than one bike with different pedal/cleat systems and don’t want to buy a separate power meter for each. Real-world battery life has been reported by some reviewers as shorter than Garmin’s 120-hour claim, so budget for more frequent battery swaps than the headline number suggests, particularly if you’re using ANT+ and Bluetooth broadcasting simultaneously.
Data You Get
- Total power, left/right balance and cadence
- Seated vs standing power split
- Platform centre offset and power phase data, useful for pedalling-efficiency work like our single-leg turbo drills session
Price and Availability
The Garmin Rally XC200 is £699.99 at Tredz (RRP £959.99), in stock at the time of writing.
Verdict: Who It’s For
The XC200 suits triathletes who ride SPD cleats — whether on a gravel bike, an indoor smart bike, or simply a personal preference for recessed cleats you can walk in — and want accurate, swappable power data without committing to a single pedal system. If you ride road-style cleats exclusively, the SPD-SL-compatible Rally RS200 is the more direct fit.
