Minor problem with inserting seat post. Hidden clamp was probably slightly to big. Vendor sent replacement, but meanwhile i striped black colour from it,  and that was enough to insert it.

Stuck at the progress at the moment, because waiting for handlebar...

T47-24(86.5mm)for shimano crank, use the 1mm shim on nds (supplied)

Can this be verified as true info? I can not find proper info about that. Frame is 86,5 mm and I am installing GRX600 2x10 crankset. I got three shims 1/2/3 mm width
Also ordered specific tool for BB T47, 48,5/49 mm width.

in my direct experience with ultegra crankset and without shims it touch and grinds the BB. with 1mm shim is ok. maybe grx crankset is different. just do a try.
i cant post a pic now, but i can do it later, if you wanna see grinded nds crankarm and bb

The seat post clamp that came with my frame was poorly finished, and the curvature didn't match the seat post. As a result, the sides have dug into the carbon post and cracked it after only a few hours on the bike. As you can see in the image, there's a big gap between post and wedge.

I've messaged TanTan, but haven't received a reply yet. I've sanded it down to match the diameter, hopefully it works now; the seat post has to be replaced though.

I finished my bike and made some 20 km but there is a problem:

Everything is properly tightened but it is not ok to have such play/woble on bottom bracket.

From what I can see, it looks like the BB is not moving in the frame, so it could be a problem with the bearings maybe?

Edit: just remove the crank and look what is causing this problem. With this kind of movement it should be obvious where the problem is.

I do not understand what do you mean BB is not moving in the frame. BB is tightened. Bearings move. I have removed crank and spindle of crankset have to much play inside BB. Means tolerance on BB is fucked up. I contacted seller but they refuse to warranty that since several month passed from delivery.
I will order new one but avoid Kactus BB cause they are no good.

If you can, just get a BB from a decent brand and not from Ali. My experience with Ali bb's has not been great and I will use Shimano from now on where I can.
