REPAIRED FRAME OR FORK

The issues surrounding the modified frame set are repeated for the repaired set.  Look for indications of heat application and/or welds, where they should not be.  Again, experience with repaired frame sets is the best teacher.  If I see such apparent repair work clues, I back away from the set.  Heat application, in the hands of an untrained person, can wreak havoc with a high end frame set.  However...

Sometimes, and I don't even know how often this happens, a frame set's repairs will be impossible to see.  Have the drops been realigned?  Were the stays straightened and/or spread to accommodate a wider cog set? Has the frame set been repainted?  Are there new components installed that don't match the others or the overall condition of the bicycle?  There are clues that will suggest the need for concern, but such clues are hard to read.  Only experience with lots of frames will assist with this kind of evaluation.

About all I can suggest is that you ask the seller and hope that the answer you get is an honest one.  Other than that, you take your chances, the same as I do.  Both my 1976 Marinoni Quebec and my 198? Cambio Rino 2000 have been repainted.  Does the shiny coating hide frame or fork repair?  In the case of the Marinoni, I don't know.  But the Cambio Rino is another story.  I had to deal with the ravages that Mother Nature heaped on this lovely old bicycle.

And, my sixties something Peugeot PX10, came to roost in The Old Shed and brought with it a bent frame and bent fork.  I implemented the necessary repairs, measured and tested the results, and am fully satisfied that the bicycle's geometry and structural integrity are sound.  But both were compromised, at one time, or another.

If you happen to see damage to the seat post, be assured that the darn thing is likely seized into place.  My early CCM Formula 1 had a slightly crushed seat post with pipe wrench marks on it.  Is this a concern?  Yup!  The steel post is all but welded into place and I will have to spend quite a bit of time removing it.  To rub salt into the wound, the steering stem is set miserably high.  Can this spell frame or fork set disaster?  Yup!  The internal clamp on the stem might well have damaged fragile steering tube threads on the fork set.  Again, an expensive issue to deal with.

With structural and geometric issues addressed, the last concern is environmental damage.  Good old Mother Nature can, and will, take her toll if allowed to do so.  And a great many vintage road bicycles have been left at the mercy of Mother Nature.  And the damage that she can do might well prove to be impossible to repair.
