## What reviewers say

**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.)
