Quite literally everything is carbon fiber, including the handlebars, brakes, everything..
Metal bolts
Metal cassette
Regardless, I think that bike is downright gorgeous, and I'm even more impressed that the 3,2KG version was ridden 20 thousand Kilometers before being retired. That's the kind of usable record worth having.

I talked with a guy at my LBS who rode a 10+ bike. It flexed on climbs and sprints to the point where he felt uncomfortable pushing hard. So this super light weight is really just something to have fun talking about.

Every part on the bike is completely custom made and cannot be bought unless you wanted it made specially for you.
Oh really? Is that what custom means? Here I thought it meant they ordered it from Hong Kong and it had to go through customs.

And that's why it's a 6lb bike...if a gram could be saved, it was.

You gonna eat that?
Friction shifters = lighter weight of the shifter itself, plus shorter (metal) cable runs and shorter (metal-wrapped) cable casings. That might be most of the difference between that one and the 3.2 kg one.

honestly, probably not a lot... but in consideration of the whole concept (shift + brake lever v STI shifter), probably 5% savings using a downtube + brake lever over the STI
figure the STI shifters weigh 300g... those custom shifters weighed in a 9g....

Before the UCI came up with the current minimum bike weight, Tour racers sometimes used a downtube shifter for the front d/r to save weight.

I doubt the bike shown is 6 lbs because I see obvious areas where weight could be saved. Take the cassette. That should be a cf gear cluster, or AT LEAST have cf spacers. The cable housing looks standard, unless it's a superlight type I haven't seen before. The brake pads are twice as thick as they need to be.

I know its an old article...but I have to say, I'd be shocked at howl long that thing holds up (if he rides it). The carbon fiber chainring and rear derailleur pulleys don't seem like they would hold up for long...

If it helps here is an article about the same bike from less than a year ago.

Very impressive from a technology perspective! OTOH, my road bike comes in at 14lbs. Without looking too hard, I can see that I could take 8lbs of 'ballast' off of my body - without spending $45,000!
That said, there is probably a lot of trickle down from some of those components. Just like in high-end audiophile components, the stupid-expensive stuff eventually makes real-world equipment better for the rest of us.

Regarding the D/T shifters, while I have no idea about those carbon ones if you compare Shimano 105 brifters to 105 aero brake levers the difference is about 250 grams, minus 80 or so that the downtube shifters weigh. so it's quite a bit of weight saved.
