I managed to buy a nice but rough Orange Alpine 160. It has a few knocks etc but is solid apart from this (below) 'X' shaped crack around a vent hole in the swing arm brace (behind the seat tube).
The seller says it hasn't changed in some time but I am somewhat heavy on kit.
Do I get her welded up or leave it because it won't get worse?
Please either reply with some technical knowledge or prior experience...I'm not one to have bags of cash to just go and replace it all.
I have dealt with numerous cracks etc but never one like this-hence the thread.
