Help identifying an 80s Trek frame

Hi, wonder if anyone out there can help identify a Trek touring frame I just bought. Neighbor at a stoop sale sold it real real cheap. I think it's early 80s. It's white with a blue-silver downtube decal and headtube. The only other decal says "Shimano Dura-Ace EX system components." The serial number is 051595. It's got some scratches and a spot of rust at the rear brake-bridge but no dings or dents and it's straight. It might even be my size (62cm c-c).

Thanks a lot.

It is amazing how easy this is to do with pictures and a serial number. Do you happen to have them. Roger

Try this site. It should have several ways to place the bike.

1983 25" 640 according to serial lookup at vintage trek

catalog doesn't show it in that color, though. hmmm.
DA-EX sticker seems like it should be on an 81 719, 759 or 959, or 82 759.

The white looks like a repaint. Rattle can?

Looks to me like the whole bike was originally blue (like the metallic fleck paint on the head tube and around the logo) and someone just added the yellow "United States" tape strips to hid the cheesy paint lines. Frame looks to be in good shape though and I'm sure Lester has got it right that its a 640.

The paint is probably original and it is a good'un. The 959 was the dura-ace EX equipped version of the 900 in 1982. The 957 was the campy version of the same bike. The catalog entry is here on page 11. The paint is a little light, but that may be fade or it may just be your camera. The serial number will tell the tale.

Thanks to all for your help.

I'd love for it to be a 959, however with the touring bosses and the serial number it points more to the 640, no? Yet the color (which on close inspection doesn't look like a rattle-can job, even a skilled one) and the Dura-Ace EX sticker confuse the issue. I don't see any touring frames that came with Dura Ace EX. And the serial number doesn't lie, right -- previous owner must have gone to the trouble to try to make it resemble a 959. But if you're going to go that far, why not remove the extra bosses? Have I overlooked something?

Why not remove the bosses with a repaint? Many people wouldn't notice, and maybe he left it so later someone would be able to restore it to its original glory And I'd trust the serial. I had to ID my '83 600 that way after a repaint. And yours reminds me of mine.

It definitely not a 900 series frame. The lugs, brake bridge, dropouts, and stay ends are all wrong for that. 600 series is much more plausible. Don't be mislead by the "EX" sticker -- that was likely placed long after the frame left the factory. I have a few of them here, in fact...

Yes, I trust that it's a 640. Whatever it is, I feel ahead of the game, since she sold it to me for $5.

I plan to build it back up again. The original 640 fork looked to have quite a rake. Would I do best to replace it with something similar? (Is carbon... gasp... a bad choice?) I don't plan to make this true to era, just a very serviceable long-distance tourer.

oh, say...I have a real genuine 1982 959, currently racked in the shop. Columbus, blue and white scheme...would you sell me one of those EX stickers?
