Lightweight lugged steel frame identification? Suntour GS dropouts

I picked up this frame for a few dollars on ebay. Wondering if anyone would have any idea as to what it is?

Apparently its new old stock in grey primer. A bit of surface rust showing through the primer which I hope isn't too serious once I strip it back.

It's got nice looking lugs with Suntour GS dropouts.

Weight is only 2.0kg and the size is 56cm

No numbers anywhere that I can see.

2.0 kg for 56cm kind of indicates 531 rather than SL (SL being more like 1.9 @ 56, iirc ?)

There's got to be a number stamped on there somewhere - it looks Japanese.

I thought Japanese too. Would that mean its some sort of Tange tubing? The dropout spacing was 120mm when I got it if that helps any.

it has lugs that are either Prugnat or (more likely) copies, and a welded BB shell. That particular shifter stop was something I've only seen on Japanese frames. Surprised that there's no serial number!

They look like Prugnat 62D lugs but the points are a little too long and the distance from the head tube to the bottom of the "birds mouth" is also too long.



Better quality Japanese make is a good guess...

Like everyone else, I'm thinking Japanese too, early 80s. What makes you think it's NOS, rather than a respray? Have you scratched the primer to see if there's any color underneath it?

Not as familiar with the America, but it's not a Professional. All the C&V Pros lack eyelets on the dropouts, and have scooped (instead of flat) seat stay ends at the point where it connects to the seat lug.

i hadn't seen this particular shape of a downtube stop for shifter clamp until disassembling a 1980 (ish) trek 412 i bought recently. it's made of ishiwata tubing. i'm not sure where the frame was assembled (either here in the u.s. or in japan). the 412/414 is a little weird. it's a good kind of weird though.

The only other bike I had with Ishiwata was a Lotus Supreme. I don't remember the drop outs, but think they were Shimano. Good Luck

Trek used a similar stop, but didn't spot-weld them as appears to be the case with this frame.

The lugs have some differences from my '79 America. My America also doesn't have the downtube stop due to being stock with Barcons. It could be a later model, I guess.

I only think it's NOS as that's what I was told when I picked it up. There was just bare metal under the primer. It's already got it's first coat of "cottage green" paint. I think I'll do a white outline around the lugs.

I'm going to build it up with a campag veloce gropset. I haven't done this sort of thing before on an older bike so hopefully all goes well. I'll get some pics up when its done.

Thanks for all the replys guys.
