1979 Trek 937

According to the Vintage Trek site, the serial number along with catalog matching components suggest this is indeed a Columbus 937. It could be a Tim Issac build as he joined Trek in 79 but I'll never know. Willing to be optimistic, however. This will get a new decal set, cleaned, polish the components, clean any surface rust, and ready to go. Previous owner upgraded the rims which is great. Only thing I can tell not original is the rear hub, saddle, seat post. Enjoy!

That is a really nice find. I really like the old Trek racing bikes; I have a '78 TX 900.

I distinctly recall something about a "TSI" stamping on the BB shell of bikes Tim built. Maybe [MENTION=20548]JohnDThompson[/MENTION] can confirm?

I know I've seen pictures of it, but I'm having a heck of a time finding anything now I need it

Ain't that just the way it goes?

Edit²: Got the initials wrong.
Edit³: And apparently my assertion was wrong, per the Vintage Trek site, pertaining to '80-'86 models:

The 58 or 60 refer to the angle between the seattube and the downtube.

Thanks all. It should be a good spring project. I'm hoping I can get the Campy parts a little shinier but we'll see.

The TSI markings on Trek's proprietary investment cast frame fittings were Tim Isaac's initials; he designed those pieces. Those weren't available until considerably later than the OP's frame, say 1984 or so.

And I doubt Tim was directly responsible for brazing that frame. The only brazing I saw him do was for team bikes and prototypes. His position was more administrative, as an engineer and designer.
