I’ve tried it on 2 different wheels and get the same results. I was building this board for @SyrusB, and noticed his pulley was off center when I got all the parts from him.
No big deal, I’ll just re-center it, right?
nope, doesn’t want to ever get centered on the first wheel, so I try a second with the same outcomes.
I’ve installed abec 11 pulleys from enertion (the old aluminum ones like this kegel pulley) countless times without this level of persisting issues.
edit: it is a 12mm pulley form @torqueboards
