I can’t really comment on Garmin reliability as the XC200 are the first pair of power meter pedals I’ve had from Garmin. I bought the XC200 because I wanted a power meter pedal specifically for SPD cleats. I have a set of Assioma Duo which have been very reliable, but I really don’t like the cleats. I’ve been using Speedplay for years so I’m keeping an eye out for Wahoo releasing the Powrlink Zero. If you’re anything like me then going from a dual-sided system such as Speedplay to a single-sided cleat will feel like a step in the wrong direction.
