Does everything work ok with the original serenade freehub ? If yes I assume the DT Swiss freehub is not a 100% compatible part (even though they say it is) as it's from a third party wheel.

Good to hear tix92
And the bars are pretty much the same weight as the real thing
Looking forward to you build!

Your problem with the freehub is due to bad tolerances.
When you are torquing the axle you are making contact between the freehub body and the hub body.

I guess you have to add shims between the inner race of the freehub and the inner race of the wheel bearing.
Check ebay for shims, easiest way.

Thanks for all your help! I turned a new spacer which is 0,2 mm longer - problem solved! Everything works fine now.

Took mine out for a bit of a longer ride yesterday. Still blown away with the comfort and smoothness compared to my Winspace. I'll be using this bike in longer road races so I can follow up once I do a few of those. Otherwise I am superrrr happy with my purchase. For under $700 shipped to my door, it's hard to complain for a 7kg build. Only thing I am curious about is the derailleur hanger and the seat post. Are these the same as the original specialized ones?

Quick update. I've been on some longer rides and I really enjoy the bike. It is super comfy and exactly what I was looking for to do longer endurance rides and climb heavy road races. I definitely do notice that it is not as stiff as my Winspace when sprinting. Probably losing some watts so I will definitely be sticking with my Winspace for crits ;). One additional thing to note about the rapide cockpit from aliexpress; the computer mount nut that is in the handlebar is crap. It will loosen and eventually come out of the handlebar. I almost gave up on it and ordered another solution, but I was able to use needle nose tweezers to squeeze in a much bigger wing style nut into the handlebar to properly hold my computer mount. Something to note, so I would advise against ordering those bars unless you really feel like tinkering around with nuts and bolts.
Picture of my Winspace for fun  ;D

That's about the size of the gap I have on mine. Could probably be reduced with the genuine roval spacers

This issue has actually been discussed at length on the Weight Weenies forum regarding the genuine SL8 as well. It looks like the bottom of the transition spacer isn’t perfectly flat — it dips at the front and ends up rubbing against the top tube.

You could try lightly sanding it down using fine sandpaper on a flat surface to level it out, or alternatively, order a set of genuine spacers and see if that resolves it.

This is exactly what I did with my frame, size 56 (but mine is from Taiwaneisen and you might think it is different…)

The computer mount nut gets a lot of mentions. The one from tantan seems secure. I'm running a magcad and wahoo bolt, so the lever arm is much shorter and the mount is lighter with greater bar contact than the roval clone.

Most of my wish list items on Ali Express either no longer ship to the USA or the link has been removed altogether.

Can't even find the ones @greengoblinbean posted anymore ;D

Wow you're right! Even in my order history I click the link and it's not there. Guess I got lucky as these only set me back $80 and the handlebar itself is actually great quality. Reason I went with these is because Tan-Tan's max stem length is 120 which wasn't adequate for me.

The bars at the Aliexpress link posted by @greengoblinbean are still available to me. I'm in the UK though so it does look like Aliexpress sellers are  removing the links to products for US based customers.

Those bars are currently 92 GBP for me (roughly 120 USD) so at 80 USD, they were a great deal.
