Sorry Dell, that's rubbish. I lent a bloke at SSEC a bolt (which is why I only had 3!) as two of his had fallen out. His was creaking but hadn't folded. I've seen loads of people ride with a bolt missing without any problems but it appears surly rings are known for folding.
rootes1, why retaining fluid and not loctite?
and yeah the frame survived thanks, finest taiwanese wrought iron 😉
