To bad the smallest available model is to big. reach is ok, but stack of 547mm is extreme. The size 47 LCR018 is 519mm.

I have finished my build ca. 2 weeks ago. Everything was easy to put together and there have been no issues so far (ca. 350km ridden).

I saw a lot of people early on mentioning problems with a slipping seatpost. I received the new version with the "grippy surface" all around the seatpost. I used the same approach as with my Cannondale Supersix (which also famously has slipping and creaking issues with the seatpost) and put grease on the frame side of the clamp + grip paste on the seatpost side. Torqued to 6nm I have had no slippage even though the roads here in Britain are quite rough with a lot of pot holes.

So far it seems like the updated version of the seatpost solved the issue?

Not for me. I got the slick version first and the grippy one later, but the problem persists.

Can anyone tell if this is normal amount of play when the clamp is loose?

When the clamp is tighten, I guess this amount of wiggleroom makes the seatpost slip because it's only forced between the clamp and a smaller part of the rear of the seatpost. It might be forced sideways and forced out of it's position little by little. Not sure how Jim will solve this. I need to use the bike and now I'm back to the strip of PU, but it's not a perfect solution.

4mm is absolutely fine.
It's actually the industry minimum, so you don't need to worry about anything.

I'm fine with the clearance, but what about the difference? I guess it's just 1mm off from 5mm-5mm to 6mm-4mm.

With gp5000 STR in 35mm, I got 6mm clearance on left side and only 4mm on driveside. It's the same with two different XMCS wheelsets. Is it within acceptable margins?

My Seatpost doesn't slip but it has horizontal play. Very annoying noises with every Pedal stroke. It May be caused by the wedge or it's just too big tolerances. Small layers of Tesa Tape didn't help. I'll try again with other Tape.

I remember that somebody Else had this Problem
But i don't find the postings again? Can anyone help me?

Just document the issue and contact LC. I got a replacement. In the meantime I got the old one to sit right with a layer of thick plastic. The PU-bag my OEM-packed SRAM Force came in.

Received my replacement seat post. DHL wanted the same amount for VAT and handling as the complete frame kit, but that was closer to correct this time 😅

Not mounted yet, but finish looks good with full texture.

Is this scratching visible on your post? Please let us know if the replacement solves the problem. And please hang on to the email where Jim acknowledges the problem and states that it's LC's responsibility.

No visible clues except the large amount of play in the frame. Scratch might be sanding, too? There might be details lost in translation. I also had the opportunity to get a straight seat post instead of the setback, so that's nice.

The Slipage is "common" problem in many bike manufacters west and east, for exemple 3t strada had the same problem even on newer models (not to say its acceptable) as mention before on the forum you can torque "if needed" to 10nm.
On the clamp it self say 6-8nm on the guide paper say 8-10nm, i talked to LC (Wendy) cause i had slip seatpost at 8nm torque with some carbon paste, and she confirmed with enginear staff if needed you can torque to 10 nm, i put more carbon paste and 10nm torque and  no more problems at the seatpost (not even over pot holes).

Note: no platics used 

Anyway i recommed any one with this problem to confirm 1º with their contact at LC.

I had this issue and tried all the tricks. I "solved" it by a wrap of plastic on the back side of the seat post, but Jim told me "The production manager said it was due to the carbon fiber layers being scratched when the seat tubes were painted black; it was a mistake by the painters during the year-end rush. " So I'm getting a new seat post. I guess you need to prove it matches the production date AND the problem persists after trying carbon paste and 10nm torque.

I got the titanium because the info in this thread said it was shorter. Came in same length as the plastic one. Weight as pictured: 22g, 17g and 12g. Last one is 3d print. Just search the thread to find the files.
EDIT: KRoser is the man with the plan/files. https://chinertown.com/index.php/topic,5970.msg100188/topicseen.html#msg100188

I adjusted the length and printed an even shorter computer mount for the Elmnt Bolt.

Very nice! But i need to ask, how did you manage to get a weight of just 7kg? I think the frame is quite heavy with 1100gr in size 52, which I ordered last week! But looking forward to it

960g in 47cm without storage (so not +50g for the hatch)
Force E1 group /RED 10-33 and RED 160mm crank
20g cut seatpost to get it low enough
40g cut steerer
1100g XMCS wheels
190g Look keo w/ titanium splines.
110 Ryet saddle

2x405g pirelli p-zero rs 35mm
2x36g tpu. Will go tubeless later

Jim has gotten the measurements of the loose seatpost and will check when Chinese New Year is over. I doubt that the outside of the seatpost is the most plausible fault. Inside of frame will vary more if there is too little resin I guess. The noise disappeared with a film of plastic from the sram groupset, but it's not a good enough solution.

Weird AF
Are you sure its the seatpost and not the sadle or the seatpost clamp, you can remove the sadle to check if it make clap sound.

That's why I'm holding the seatpost for the second sound. The same sound is also there when i release the tension on the seat post clamp.. It's not the saddle. But I can remove it just to make it clear. It would be very strange if there was an adjustable tension in the saddle area that could be triggered with a nudge in the seat post.

This is with mounting paste applied but not tightened. I'm not sure I'm comfortable with the message from Jim to tighten to 10nm to hold this in place. The clamping mechanism is not meant to hold the seat post in place in all axis, is it? Just to hold the position up and down..

Well, it did not get tight with carbon paste and tightening to 10Nm, as Jim suggested. Hoping the problem is with the diameter of the seatpost, not the frame. Not sure how we will solve this one..

Kroser: I will measure again after these couple hours of rolling. They where only 34mm right after mounting on the IW26mm XMCS wheels..That's about the same as 32mm GP5000 STR that has been rolling for a while.

Tried my bike today. All good. 7.0kg with one side missing bartape. Could easily get to 6.8 with normal tires. These are the TLR RS 35mm at a disappointing 405g each. 35g more then advertised.
