I’m new to smart trainers and I’ve been I’ve been enjoying both TR and Zwift since I bought a KICKR (my first trainer) a couple of weeks ago. But curiosity got the better of me and I decided to compare the KICKR with my trusty power2max Type S and I found that it’s consistently reading high.
For example, here’s a Goddard -4 I did the other day in ERG mode: DC Rainmaker Analyzer
The KICKR seems to track the p2m quite well, but is consistently around 10 W high.
And a chilled out Zwift session from today for some recovery (ignore the gap in the middle when ELEMNT paused itself): DC Rainmaker Analyzer
While the difference isn’t as obvious here (more like 5 W), but the KICKR’s readings are quite spiky and erratic in this case.
When I look at DCR’s analysis, it looks somewhat better behaved: DC Rainmaker Analyzer
Is this normal for a KICKR (or any smart trainer)? Am I just being too fussy?
P.S. I’m using the latest firmware (v4.2.1) on the KICKR.
