Sorry if it’s already been covered but how much flex between the basebar and monopost is deemed “acceptable”? If I shift weight there’s a small, but very noticeable movement from side to side...makes me pretty uncomfortable to be honest.I've noticed this a lot on the trainer. I don't mind it flexing a bit but I'll admit to being a bit nervous of what'll happen outside if I hit something with the front wheel.
I don't really want to test it but it bends enough for me to *think* I could snap it. I'm likely wrong, it's probably far too strong for me to snap, but I'd love to see a body weight dropped on one cup to indicate it's unlikely to give out.
I did attempt to make a video but it wasn’t particularly good (needed more hands).
Either way I found out a couple of things. *most* of the flex is actually the cups, at the far end they’ll flex by just under a centimeter with a reasonable squeeze. Honestly I’m less concerned with the flex knowing it’s coming from the cups rather than from the pole.
A few days later I noticed that the pole had dropped ~0.5 cm over 3 weeks. I’ve moved it back up & tourqued it to spec & it feels a little more stable. Given the monopost touque spec is different to the other bolts it’s possible that it was installed a little loose. I assume the pole isn’t supposed to slip after 3 weeks of trainer rides?
I had an identical experience.
