Recently acquired this Atala Grand Prix and was going to use it as a grocery getter but now I'm not sure that it is safe. I'm well aware that the brazing and craftsmanship of these frames tends to suck, still I'd like to use it. So there are two areas of the frame that are compromised and I thought I'd get the opinion of some experienced framebuilders so as to be somewhat safe. The lug is the lower headtube lug attaching to the downtube. There is also a crack of sorts that appears original to the frame on the rear seatstay. Do these cracks render this frame unusable and graveyard bound or is it still rideable? If it's a repair that is needed, I hope it's a really, really cheap one, otherwise I guess I'm on the hunt for another affordable Italian frame.
