Well, I found this frame the other day on CL and it looked interesting enough to take in. It has no serial number, just the frame size on the BB and steerer tube. It has Gipiemme dropouts and a Dura Ace 7410 headset, The seatpost size is pretty close to 26.8 because that the largest post I can fit. The BB shell measures 71mm and seems to have 36 x 24 threading although the threads are too rusty to allow smooth engagement of the cups I have on hand. The lug cutouts look pretty interesting but I don't know what they are - any suggestions? Some lower level Italian frame?

BTW, the frame is pretty heavy, about 3.4 kg with fork! The rear spread measures 121 mm.

Any ID for the lugs or the frame is much appreciated!










Thanks - Jim

Looks like a good quality frame from the very late 70's or very early 80's (because of the cable guides above the BB). Maybe not quite top of the line because of the Gipemme DOs, which were used mostly on 2nd tier bikes, but the completeness of the brazed on features makes the frame quite a nice one. Add to that the cool windowed lugs and it must have been a really pretty bike when it had it's original finish and graphic.
What's the I suspect it's Italian but the width (70mm) and threading of the BB can hep confirm that. Otherwise the absence of pantographing could also mean it's one of those frames contracted out to a builder/contractor by a few manufacturers, which can make it a bit difficult to nail down exactly what brand it was.... what seatpost diameter fits in the seat tube. That measurement can also give a hint what tubing was used, which can also sometimes confirm where it might have been built... Someone in the forum might also recognize the distinctive shape of the lug windows..

italian but maybe mid-range frame (seatpost size.....gipiemme DOs...weight)

maybe columbus Aelle or Zeta ?

26.8mmm would be consistent with straight gauge CrMo. A good shot of the rear brake cable guides might assist us in identification. Based on my experience with Italian frame geometries, I'll bet it rides and handles extremely well.

Here's a better shot of the cable guides. I agree with Italian, second tier, straight gauge CrMo based on the weight. And the DuraAce headset would not be in keeping age-wise with the top shifter guides or the 120 mm spacing, would it. I do like the fork tangs but the windows are like nothing I can find with my Google searches. There are some gaps in the braze joints but I don't think it's French.
