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.

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?

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.

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.

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.

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..

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.

I installed a SRAM Rival XPLR 2025 brake system and needed M5 screws.
However, there are also brake calipers with M6 screws; please check this on your bike yourself.

You needed washers with those 35mm titanium bolts, right? Mine stopped with a 1-2mm gap. I guess the bolts i checked from my canyon was 27mm, not 32mm, because these did not even reach the threads.
