I bought this beauty
19” c - t 17” c - c.
Columbus Genius Nivacrom with matching forks.

welds look lovely - comparing them to my Columbus Genius Bianchi Nth frame they’re too fine and smooth to be normal TIGg welded.
It features Ritchey drop outs

any help in determining the age, manufacture and construction?

I believe Koue is an MTB trail in South Africa and a BCI event location.

it may have been a team race bike.

Thanks
@kingoffootball seems to think Fillet brazed. How could I possibly check to see (bar stripping the paint off) ?
Do people go to the trouble of faux fillets?
Saracen used them, on a frame with tubing of this quality though I would think they are real I am just being cagey as the gods of Retrobike can sometimes be very unforgiving ;) 🤣

Just been looking up about Genius tubing, I was pretty sure it was designed for TIG welding, which it is..... Although I have just read there are different tubes designed for fillet brazing and lugged designs...

That’s true about the genius tubing but a quick internet search of ‘Columbus genius fully brazed’ brings up multitudes. I think it was easier to TIG rather than specifically for that - correct me if I’m wrong! Would be interesting to see if this has been faux or it’s genuine !

As per my previous post there were Genius tubes made specifically for fillet brazing. I only mentioned the faux fillets as standard Genius is designed for TIG welding. This looks like an inch headtube and made for cantilevers so I would say 92' to 95'....

Thanks - just read your message carefully and apologise for mixing confusing things
the underside of the BB shell has minimal printing. I was guessing around that period too - have never heard of the brand though
