Got one!

That's a shame but look on the bright side; at least it was only beater money and not coronacycling priced. I don't think I've ever seen a main tube go like that before, just rotted out chainstays. Keep your eyes peeled, something similar will turn up sooner or later, mixtes and other female frames don't tend to sell as well as mens ones.

I can't even strip it yet, dump closed...

Changed my mind after another inspection. This bike is in my head already. I don't think it will fall apart any time soon, and I'm not that heavy. And I don't ride like a sack o'spuds anyhow.

Excellent news. The more quality lugged 531 bikes that are kept on the road, the better.

Could you clean up the area carefully with a needle file to see how bad it is ? It doesn't look too bad from what I can make out .

Finished it today!

 

[DCBassman]

OK, I'm back...
Need suggestions for new calipers to fit this.
I understand that it's fairly simple to mod the frame to take standard dual pivots, assuming the drop to be sufficient, which I doubt but will measure properly at some point soon.
Otherwise, it's long-drop nutted dual pivots. What's best here? Don't suppose for a moment there's any Shimanos that would fit?
Aha, a quick google says there are!

Once you have the known drop you should find something

I got a pair of 105 dual pivots for my old Dawes but I'd've had to drill out the existing holes to fit them so kept my existing ones with new pads- it stops slightly better than it did before but I'm used to that!

I already did that, Koolstop Salmons on the Weinmanns. Still not remotely good enough for the hills around here. The same rims on the Scott, with 105 5500 calipers and Salmons, would put me over the bars easy if I was not careful. The unbranded ones originally from the Scott, if they're long enough, are the prime candidates, but will require the use of a drill...
I'm not concerned about keeping the frame pristine, far too late for that even before I got it. But if go down that route, I do want to make a good job of it.

To save drilling the frame you can drill the concave washer central hole out and then use a long allen threaded bit to secure them . Sometimes you might need to slightly open the frame holes but not always

I'll certainly check carefully before wielding the cutting tools!
