I do standing efforts every now and then, but I'm not massively strong or heavy. Wahoo kickr weighting a tonne does help, got far more problems with "dumb" cheap turbo
Standing up isn't the issue. I can stand up and ride at 100W or 500W basically steady. It's doing proper sprints that are going to be unkind to frames and turbos.
I was doing a sweet spot workout with increasing durations of ‘seated sprinting’ at 200% ftp, but then after the workout finished, thought I would give it the beans for 10 seconds, and this happened 2 seconds in.
No issues beforehand.
I have cracked a carbon handlebar on the turbo before though.
