Out of ideas: chainline
Hello, I’m stuck on chainline at my first fixie build
Pictures gallery - https://www.dropbox.com/sh/e2kxkyhe533r33m/ds9KwLFj6e
Measurements with a ruler: front ~45mm / rear 41mm
Bottom bracket: campagnolo 36x24f cant remember axis size, but I really made there all I could before reaching frame. (see pics)
Rear Hub: Sturmey-Archer Track hub 120-135mm
Frame rear dropouts spacing: 120mm
- Front is as close as possible
- Cog is flipped to right side (normal position)
See pics how it looks, chain sits tight, thanks to brutal chainring teeth, but i can hear the chain and it's quacks sometimes which makes me nuts.
Any suggestions?

I don't think that frame is 120mm rear spacing, or at least it wasn't when it was made. If it's been modded, that could be your problem.

Well yeah its centered, since hub is symmetric, where you managed to see that kind of a problem?
All 1/8, not too tight like a sting, i think aout 8-12mm variance
You sir are wrong, frame is 120 since was created, and all it's bros and sis are the same.
Can push in 3-4mm spacers w/o beding anything.

Frame is Concorde Colombo 1988
3 main tubes are columbus AELLE, dropouts Ultech
front frame badge - vertical word "concorde" not casual Bird logo.
Is it possible that older frames (pre-90s) were 120?
Meanwhile, how about adding spacers 1 + 5 mm on non-drive side and then re-center wheel at workshop?
It loos like that will put me 126/2-18=45mm almost same as chainrigs
feedback?

Take it to a shop and don't say a word. The attitude you've already shown in this thread isn't going to get you very far.
The repair is easy, but the tools are expensive and you'll never need them again. Just pay a shop and wash your hands.

Pfft. If a fatbike can run a hub off center, there's no issue there.
There is, however a problem when you flip your flop or want to swap in a new wheel.
Seriously, a frame alignment should be like $20 and half an hour at any shop worth a ****.

it would be more useful if you can tell whats wrong, how to fix that and which tools should be at works.
And fatbike commonly uses hub with a cassette, which is designed to be off-centered by default. I think stillcovale was talking about centered trackhubs, like mine flip-flop.

Is english your first language?
Edit: fine, google up "frame alignment" or "frame coldset"- saint Sheldon has a great article. The key is to get the dropouts parallel once you've set the stays.

obviously no, I am from Libya.
Whats wrong with you people? Why so rude and mean?
I provided all information i could, was polite, but receiving negative attitude and "go google".
Something wrong with a frame, fine, thanks for pointing that out. But none of the comments yet solved the issue with a chainline.
Even with perfect and brand new frame its still 46 / 41 mm with a 5mm gap

Your cog is slipping.
We're American.
It may be because you came in here saying know-it-all things like like this (even though you are wrong):
