I think it's from '94 or '95

Well, it's not from '95.
I found the one from that year.

Anyone an idea at weight of Columbus Brain frame and forks?

I have 2 bikes, Columbus SLX, and Brain. 56cm c-c.

Both identically equipped with late 90s Record Ergopower. Yet the Brain feels lighter to lift. I don't have access to any way to weigh them.

As I recall Brain is heavier (probably not by much) than SL, TSX, but might be lighter than SLX, SP, SPX.

According to the file I uploaded in pdf, the complete SLX (11 tubes) without cutting is 2,040 gr
In the 2nd file I uploaded in image, the Brain weighs 2,150 gr
So in size 56 the Brain will be about 50 or 60 gr heavier than the SLX
By the way, the SLX New from 95 is 10 gr lighter than the previous SLXs
If you look closely at the thicknesses, you will see that the seat stays are thicker in the Brain, hence its extra weight

No mention of Columbus Altec and Altec 2. Altec helped Laurent Brochard (Festina Peugeot) and Luc Leblanc (Polti Coppi) to win their world Championship UCI titles

I owned a late 1990's Billato built frameset (for Marin) with a shaped Columbus tubeset profile. I think it was Brain(?) or Zona(?) in a Columbus Megatube shape.. I found it to be a Very harsh ride with 25mm pumped to 7 B (100psi).
This pic was quick from the Internet, Top and Down tube were shaped. I should have bought the lower model with round Thron tubes - but groupset was Mirage when I need Veloce as a minimum.
