This cannot be a sensor issue. I have tried the sensors in the Wahoo app and it records Cadence and Speed (MPH) just fine.
I noticed…In Zwift…my power output varies as i choose a wheel size (for speed sensor). With 20" I can hit a Cadence of 115-120 and I am only seeing 160w. That cannot be right. I am pedaling so hard!
I tried setting it to 700x20c and I was at 350w. In order to get down to the 185w in SST Short I had to slow down to like 70 cadence.
My Spin bike has an 18" diameter front wheel. What should I pick for that? Also, I only have the option of choosing a trainer or rollers so I end up just picking an unlisted trainer.
Another question…where should the sensors be? I have one on my pedal crank arm up by the crank (opposite where the arm connects to the pedal) and the speed sensor I have placed against the spin wheel (flat against it top facing out) as close to the hub as I can. Do either placements matter?
I have never had an issue with the Cadence. Just the speed sensor (which I assume is what calculates the power in rides like SST or FTP).
@Justin_Thackeray thoughts?
Really frustrated with this. I cannot figure out what is causing the problem. The sensors appear fine, reporting fine in other apps. Maybe I just need to nail down settings in Zwift. I don’t know.
