What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Garmin Rally RS200
Two whitelisted cycling testers cover the exact RS200 and both rate the system accurate, clean-looking and versatile but pricey. BikeRadar reviewed the RS200 directly (4.5/5); DC Rainmaker bench-tested the RS200 SPD-SL variant against a Tacx NEO 2 and Stages LR (RS200 tracked near-identical to the Stages), and weighed the SPD-SL cleats at 40 g/side. BikeRadar flags the premium price and slightly delayed pickup from a stop; DCR noted the unit failed to compensate for a temperature shift on a cold day, fixable with a manual zero-offset. (Cycling Weekly was dropped: its hands-on test pair was the RK200 Look-Keo trim, not the RS200.) (2 sourced reviews, 1 lab-tested.)
Praised: Accurate, reliable power data that tracks closely with reference power meters (Stages, Quarq); Best-in-class cleat compatibility — one spindle swappable across road and off-road pedal bodies; Clean, normal-looking pedals carried over from the Vector 3.
Flagged: Premium price versus rivals like the Favero Assioma; Weak temperature compensation — needs a manual zero-offset after temperature shifts; Slightly delayed data pick-up when starting from a complete stop.
