Seamed tubing frame??

Post by Jack Horowit » Sat, 19 Dec 1998 04:00:00


Hi,
I've got an old frame that I was going to fix up into a winter/trainer.
I took it apart(needs paint badly) and discovered that the at least the
seat tube and head tube are seamed.  I'll bet the rest are as well.  Is
this frame worth putting any effort to fix up?  Should I just get an old
531 or SL frame?

Thanks,
Jack

Why worry if its just a beater, right?  I know a certain major
manufacturer that sticks seamed seat tubes on their Reynolds
853 frames, using only 853 for the top and down tubes.  Anyone
care to guess who?

I'll bite - who is it? I may have to shine a flashlight down the seat tube
of my 853 Lemonde Zurich.

Well, TT tubes are not just rolled up, welded, cosmetically ground,
and shipped, like 6/4 titanium tubes are.  The way I understand it
(as Hank explained it, anyway):

A rather thick sheet is formed and welded along the seam.  The weld
is then shaved inside and out; the resulting tube is then annealed,
cold worked, drawn and butted, etc.  Anyway, by the time it's been
annealed and worked and drawn out, the seam is pretty much non-
existant.

Seamed tubing today is a very different deal than it was even 10 years ago.
Welding processes are very much improved and there are steel alloys which are
not harmed much (if at all) by those processes.
