I got the frame this week, still waiting on components, but thought I would share some photos anyway. I went with silver chameleon, which doesn't really come out in photos, but looks nice in the sun.

This is with the top tube bento mount, it fits a bottle cage so its the right size I think for most screw on bento boxes. The top tube also feels pretty sturdy so I have no worries about that.

The brake mounts probably need to be faced which I'm not too worried about. I'm not sure if I should sand away the paint on the outside of the bottom bracket or not.

There also isn't really a great place to put the di2 junction boxes, sending 4 cables down the stem feels like they will get chewed up and be a pain in the ass when I try to put it in a bike box to fly with. I'm currently planning to print a small box to screw on under the cockpit metal plate thing and shove all the connections in there so I can have one wire going down the stem, which I can disconnect in the front. Sram makes a lot more sense.

Regarding the cockpit, it feels fairly comfortable to lean on, but ill give some feedback when I've had a few rides on it. It would have been nice with another few cm of spacers as last time it took me quite a while to sink into a decent aero position, starting gently really helps. It also lacks an angle spacers, the handlebars are fixed at 10 degrees.

The spacers seem to be this design:

From looking around a lot of TT bikes are around 9.0-10.5kg for mechanical, so it seems pretty comparable to an entry level TT bike. Its pretty tempting to get one
