I’ve heard the original ST4 has problems with the chainstays snapping or something similar, so they changed them from round to square – is this right? Seen one on ebay, tempted, but worried I’m buying something which I’m just going to break… I’ve also heard that Orange warranties aren’t very good either!

Cheers.

Not an expert on st4s, but i know warranties are nearly always for the original owner.

Don’t quote me, but I think it was a flex thing that made them change to square tubes rather than snappage.
