Trek 910 identification and price

I'm looking at a bike for sale that the seller has only labeled as "Trek". I wanted to make sure it's at least a decent frame (I'd be plenty pleased with Ishiwata 022) but on further evaluation it looks like maybe a Columbus tubing decal? Are my eyes deceiving me?

with no color wrap behind the Trek seat tube text, I'm guessing this makes this a late 70s/early 80s Trek 910 or 930. Am I correct? Should I look for anything else?

Also, this has quite a bit of rust and no crankset or wheels. How does $200 sound for this, given the condition?

$200.00? Twice as much as I would pay, based on what I see in one picture. My guess is that the seat post is miserably stuck. That said, Trek is a pretty good name and they did/do build great bikes.

I agree that seat post and whatever is going on with the binder need to be sorted out first.

A Columbus sticker doesn't automatically mean a full Columbus frame/fork. Bianchi was using a lot of TreTubi Columbus and Falck stay and fork frames during this time so it stands t reason Trek may have been doing similar things.

No crank or wheels? What else is there? Does the stem move?

This could be a 900 series Trek from the late 70s which would make it a full columbus frame. These are really nice bikes but we'd need more pictures to give a valuation. $200 is likely more than I would want to pay without a crank and wheels if the paint job is shot. I'd try to negotiate the price down given the obvious issues we can see from the one pic. That said, yes this could be a top end Trek from the late 70s and I think those are the most desireable of all the Treks. I have a 1978 Trek TX 900 and a 1979 510; both are very fine bicycles.

More pics coming then!

it's listed for 300 and it has wheels, but I'm going to convert it so I asked the seller if they would do 200 without the wheels.

I also am still wanting to confirm 100% that this is a 91x or 93x. I'm guessing 915 since the derailleur looks like a Suntour V-GTx? The Dow tube logo places it as pre-1984, and the only Columbus tubed Treks I can find without a color wrap behind the text are those circa-1980 900 series. Let me know if you know of any other possibilities!

There are some nice parts on this bike: suntour barcons, first gen dura ace sidepulls maybe (something high end for sure), and quality deralleurs (I can't make them out though). Those wheels have quality rims and likely quality hubs. I'd offer $250 for the whole thing. That seatpost is an obvious concern. I've seen worse looking paint and you might be able to salvage it to your liking or, if not, a repaint is a possibility. If that's a Columbus tubing sticker (and it looks like one), I don't know of any Trek tretubi bikes with 3 main tubes being Columbus (there were main triangle Ishiwata and Reynolds frames).

The chain stays look too long for a 930. If it was a 930 and the seat post/stem was not stuck, I would pay $200 in my size. I assume someone that wanted the 910 geometry would do the same. The early Treks are great and do not come around that often. I do own a TX900, 95X and a 970. All Columbus and all great. Agree that there are some quality parts (if they look better than the chain...)

yeah that chain is... not a good sign.

I already have almost all the components for the build already, so any salvageable components that could be sold (barcons) would just offset the price for the frame.

Seat tube lug has been mangled by driving the seat post too far in, and the paint looks pretty toasty. That being said, if you can confirm through the serial number that it is indeed a Columbus framed Trek, for $200, get it if its your size.

Update for those interested:

Got the seller down to 175 with the wheels. Seat post will take some work to remove. Here's components on it:
Dura Ace FD, brakes and levers
Mavic stem
Shimano Crane RD
Barcons
Campy dropouts/fork ends
Shimano BB (not Cinelli)
Maillard Helicomatic hubs, Mavic rims

Bottom of BB shell has been repainted and can't read the serial number. I'll have to sand it down to read it (so...stolen?).

They say it's been in a basement for 30 years. If true, they've got a serious leak problem in that basement.
