Can anyone confirm the model of this Trek? Looks to me like an '82 412? The seller is asking $145 (which I thought to be a little steep).

This is not steep for a full ishiwata 022 bike but rather a pretty reasonable price. If I lived in your neck of the woods, I'd own that bike by now since it looks to be my size,

Not a 412 since that had an ishiwata main triangle only; looks to be a 515 which came with cyclone derailleurs. This is a fine bike at a reasonable price; buy it if it fits and checks out.

What size do you suppose this one is? It kinda looks to me like a 56cm.

Well you can't be certain from pics but looks to be a 56 CTC. Seriously this is a classic bike at a reasonable price. Heck you could sell it here on BF for more than you paid for it and we're a bunch of cheapskates.

Get the serial number. It will tell everything. And if it was my size I too would have bought it already.

I am going to agree that it looks like a 22 1/2 in frame going by the head tube length.

I ride a 58 to 60cm. I'm kinda worried about it being to small, but then again I don't really want to let it slip by either lol.

I ride a 58 also but I have a 22.5 inch Trek (had two but sold one) and it fits me fine. But that's me.
The guy says this bike is 1977-1980 but it's not a late 70s model. More like 80-82 or 83.

I also ride a 58-60cm frame but it's the top tube length that is the deciding factor. I have a 1981 Trek 716 with a 24" frame that is pretty tall but the top tube is just right. I have owned a 1984 22 1/2 inch Trek 660 and rode it with a whole lot of seat post. Not ideal for me. YMMV.

OK fine...the guy accepted my $125 offer.

It's cheap, I'd be all over it.

I'll post better pics after I pick it up Thursday.

I would say the bike is a good deal at that price. This one is a 22 1/2 inch 1982 model which was the only year they had the aero shifter's and Grey paint. As for size I would say go check it out in person these frames ran about 57mm square be metric which should be fine if you typically ride a 58mm.

What was it about gray paint with Trek in the early 80's? Pretty good deal at $125. Ishiwata tubing puts it on par with Fuji Club bikes.

83 was the last year for that head badge design. That's all I got....LOL

My 710 from 1978 is the same color.

I picked it up last night and didn't get home until after dark so I haven't taken any pics yet but it IS just as crusty as it looks. It seems like it'll clean up pretty nice tho.

Post pics up. wanna see it .. :-)
I have a 1981 613 thats a 24" frame. its a tad on the small side but still very comfortable of a ride.

My guess was 82 or 83 as they had the Trek Logo on the Seat tube with the color panel behind it. the 81 and earlier did not have the color panel.

Sorry guys I forgot to take pics. I'll get some pics as soon as I can. It's been overcast and raining here today. Hopefully it'll be clear by the time I get home.

OK. I took some pics. The S/N is 006187 so it looks like it's a 1981 510.

Did you measure it yet? If you normally ride 58-60, you're going to have to grow this one. I see a 350mm seatpost and a 90 degree stem in your future (or a Technomic showing a whole lot of quill). Lots of experience doing this myself. Have fun!

Yep, it's a 22.5" frame. I'll probably ride it a little but ultimately this one will be one of them that gets stripped, cleaned, lubed and sold.

That's a great deal. The Derailleurs are worth half the price you paid, IMO. If I saw that here for that price I would be on it in a second.
