Unknown frame. Please help.

Hey guys,

I recently acquired some type of road frame. I have some guesses as what it could be, but I really figure I should get online hrelp. It has long lugging, which a friend indicated to usually be Italian, and another pointed out the location of the back cable housing guide to be something usually Nishiki does. On the seat tube, there is some serial; "N 6225" it says. I googled it and found another person on a thread on this site talking about the same serial on his Centurion Super Lemans and in the same location. I thought it would be that, as the luggings looked similar, but the cable housing mount was lacking from all pictures. Can anyone help me with identifying this?

Oh yeah, it had some weird mount for the downtube shifters.

Ignore the other random stuff on the bike. I decided to throw some stuff I had together with it into something ridable.

To point out the really obvious, the fork is made by Trek. Not original though given the very long steerer tube it must have to do the threadless conversion. Cartridge BB is likely not original either.

Components and "aero" location of the DT shifters say early 1980s. Beyond that I can't help, I'm not good with frames and lugs. What's the diameter of the seatpost?

Oh, yeah, all I got was the frame. I had an extra long trek fork and decided to do a threadless conversion for kicks. The BB was something I installed because I didn't want to constantly repack it very month or so. The derailers are shimano 600s, the downtube shifters are suntour and the aerobrakes are diacompe, all from the 80s, yes. I shall get the diameter tomorrow.

Patience, maybe the people who can tell by those lugs, are still without power in the East.

It looks interesting, are there holes in the dropouts for adjuster screws? or does that frame need thos little bolt in kind?

Also I may be wrong but I think the shifters go above the little brazeon thing, which keeps them from sliding?

Just by the long lugs and the way the one is squared off at the bottom,I'm thinking something japanese- I doubt that its Italian.

you should resize your photos in another program before posting them- Windows Paint works, or some other photo program and then save them to desktop to easy find- they're taking forever to download so I didn't see them all.

Lack of top tube cable guides places the bike older. Chrome stays are a good sign. +1 Asian (probably Japan), late 1970s, early 1980s. Realize that a lot of Japanese brands were in name only: Centurion, Nishiki, Lotus, Univega all produced nice brochures and marketed their bikes, some claimed they "designed the bike", yet key features matched the contract manufacturers designs...... Once you strip the decals and repaint, a lot of the differentiating features are gone.

Almost reminds me of my late 1970s Centurion Super Elite.

Italian would have Italian threaded bb, which is pretty obvious.

+1 Resize your pictures.

Really odd location for the DT shifters stop. I always see them on the bottom side of the DT, not the top side.

It does look Japanese reminds me of Soma but the serial number is in the wrong place for most Japanese makers so I'm at a loss also.

Japanese, 1970s, at least mid-range. Same manufacturer as Centurion but not necessarily Centurion. Wheelbase would be long even if the axle was moved forward in the dropouts and it has a locator/anti-slip boss for the shifters, so I'm leaning towards mid-range model.
