This is from a previous post in this thread of a painted frame which looks to have a too large of a gap between the top tube and the spacer. I believe that the spacer or the pass through washer should be adjusted accordingly

Yeah that needs to be fixed. Looks a bit pooey.
LET'S MAKE AMERICA GREAT AGAIN!

TRUMP FOR PRESIDENT 2024!

MAGA!

Worst case scenario is you need to file down the pass through washer about a half a millimeter by sliding it on a large file like a hockey puck. It's made out of aluminum so it should go fast

I do not see any gap in the assembly of JMcarbon (European importer based in Holland)

Can you post a link to the website page you grabbed that image from?

Wonder if he'd be willing to share which spacer kit he's using?
I asked him the question on his FB: no answer. I sent him a message on his website. His laconic response is: you bought it in China, contact their sales department. On his FB page, no possibility of comments under the photos. The guy is an importer in Europe.

He's protecting the premium he's charging.

I kind of get that response, he is making a living figuring these things out and providing support. That said, it wouldn't be my response. Some of their other bikes appear to use Deda headsets so my guess would be either that or the headset cover that came with the handlebar if that was provided.

Before worrying about ordering new stuff, I would fully install everything with the proper preload and then evaluate the gap. Unfortunately i think 1-2mm is considered normal. In every bike forum catering to mainstream brands there is a thread about Treks and 2mm gaps that show expose the upper bearing. Even showed up on test bikes.

I understand his position. He's not going to saw off the branch he's sitting on.

Okay okay... A little spoiler.

But more really only after assembly.
Bottom bracket and wheels are still on the way  :D

Have you also had this gap reported by some in the head tube (upper bearing and headset)? Thank you for your contribution. ;)

It actually looks good on my bike and I don't have any gaps - and I haven't even finalized everything yet.
I have a different handlebar because the handlebar stem units didn't fit me in terms of dimensions, but that has nothing to do with the gap...

I have also assembled the bike so far and so far I am very satisfied.
I'm having my fork shortened by a friend in the next few days.

I'll probably be able to show you the finished build by the beginning of next week at the latest :-)

Just proves the fact that the issue lies with the spacers and washers Light Carbon provides with their handlebars

The spacers don interact with how the bottom cup sits on the top bearing. I think the gap is caused by some incorrect assembly or the tube race is doing something funky in there.
