This is just a stab in the dark at the components list but it looks like:

90's era tuned Campag R.D
Clavicula's
Possibly TA rings
Tune Skyline bolt on Skewers
Aerolite pedals
BCD (?) Saddle
Dia Comp Brakes
BTP Cages
AX Seatpost (now that really is a stab in the dark)
But I don't have a clue on the rest...it's a rare weenie bike were you can't pick 90% of the components. Incredible

Maybe this is the "Don't hate me because I'm beautiful" syndrome. But in this case, beauty as in ultra lightweight (the goal of ww) instead of physical beauty.

I'm going to throw in my bs flag on this one till we see a build list. I can get my bike to weigh 8 pounds if I forget to hit tear on my scale.
- Zipp rims will break if you look at them too hard
- R-Sys wheels will spontaneously explode
- The ZG crankset will never, ever exist
- Everyone needs Lightweights, even if they're fat and old
- Parts actually made of metal are SO 10 years ago

I would really like more details on the modifications made to all the parts. Not doubting the claimed weights but chopping 20-50% off already light parts merits further explanation.

Definitely a show bike in my book but still an interesting exercise, especially with clinchers.

If I'm not mistaken, this bike would be like a new record lightweight roadbike or something? According to the listings the world record lightbike was around 9.1/9.2.

Or do I miss something and there is another much lighter current record bike than the one at the top in the listings?

Of course my bike is a weight weenie bike. But it is a bike that is ridden. I am now riding it about two days a week. Also there are many bad roads here in Northern Calif. I have 3 sets of wheels, all have Fred Johnson mag rims. My lightest weigh 791 grams, next is 841 grams, next is 863. I usually use Conti supersonics 23c with 52 gram Vittoria latex tubes on the rear. I always use Velo Flex Record on the front. I have used Fred Johnson mag rims for 14 years now, with basically no problems. Fred Johnson is a friend. He is a PhD Metallurgist/ Scientist, who worked at Lawrence Livermore Lab. 13 years ago He also made Magnesium crank sets. They were 345 grams. I used them for about 5 years. Some day I will buy a Digital camera and take some close up shots and try to get them on here. All the weights are accurate on an OHAS triple beam scale. Most all the components were used for years on my Teschner. The crank is about 14 months old.
