Apologies if this question has been answered previously or if there is already an answer to this question somewhere that I’ve not found, but I’ve only recently started using Zwift. I’m using a dumb trainer with a Garmin 2 speed sensor and cadence sensor.
I’ve noticed that when I get to sprint sections I seem to top out at 7.4w/kg and can’t get past 374kw output. Is there a reason for this? Would buying a smart trainer resolve this?
