Been using Rouvy, but curious to see if the Zwift calibration will work these days…
The CycleOps M2 is not too dissimilar from the CycleOps Magnus, which has had a calibration-related issue for a while which requires that Zwifters using that trainer calibrate it via Rouvy.
You’re welcome to try calibrating the M2 in Zwift but if you notice wattage problems, then that’s a clear indicator that you should continue calibrating it using Rouvy instead.
Since we don’t have an M2 here in the office to test (we only have access to the Magnus currently), maybe you can give Zwift calibration a try and let us know how it goes. Inquiring minds would like to know.
