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) heavier 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
