I'm getting back into riding after a decade off any bike and almost thirty years since any long rides. I'm out of shape and 250lb. After searching for a couple weeks I found a bike that rides great and cost little: a 61cm Fuji S12-S from the end of the 1970s (come to think of it, that's when I quit riding much). Apart from changing the bars and stem to closer/higher to fit my bad neck and paunch, I don't feel like I need anything else.
Here's the question: what is the chance that this bike will fail under my weight? The fork is original and in good shape and the rims are Araya 700c, in good condition though old (look original).
