Sometimes you can be surprised how well those kind of things ride but then other times not.
Good luck
Thanks - I think I'm calling this one "done". The hubs are still sloppy as fook and the bottom bracket rough; even though I've tightened it as much as I can in an effort to stop it clicking on alternate pedal strokes.
I think it's about as good as it's going to get and tbh I'm sick of the sight of the b*stard thing..
