Here we go... 95% ready.

Looks really good. Will be interested to heart how it rides. Also.what handlebars are those?

Please tell us final weight when you finish it bro

What frame size is that, and what depth of wheels, 65mm? tire width?

[BeR]

600 km on the bike. I love it !

bigApple , can you tell us any info on those wheels ? They look fantastic !!

I'm putting mine together still; it's the first time I've done di2/ltwoo battery in a frame. If anyone has done the same, how does the battery attach to the seatpost? I was planning for it to fit inside the seatpost, but it doesn't.

Edit- saw the previous comment, thanks. I was a little too stressed to force it but I'll give it a try later.

How much did ye pay for the ultralight guys? Has anyone ridden it properly yet? Any opinions on ride characteristics?

Something I noticed very quickly while assembling the bike is that it has quite a bit of flex around the bottom bracket. I think the horizontal stiffness is limited because of the narrow down tube. I have to admit that I also notice this when sprinting >1000W on the road, and I don't particularly like it. When riding normally in the saddle or out of the saddle, I can't really feel it. You can already see it if you tilt the bike slightly to the side and then put some load  to the pedal, you can see how the frame flexes. Significantly more flex compared to my other bikes. In the future, I'd probably make sure the tube shapes are designed for high stiffness.

Edit: I have the Superlight... I wouldn't go for the Ultralight, as that would only make the stiffness issue worse.

I don't have this issue. Are you sure that the flex does not come from your wheels ?

Wheels are very stiff. I try to make a video tomorrow in comparison to a LCR018.
