you're quite brake ordering one. FYI, you can buy USB endoscopes for super cheap on alix, in your shoes, i'd 100% get one and make a conscious effort to inspect all tubes of the frame i receive, because composites manufacturing isnt trivial, especially now that we all want light frames again. If your layers aren't compacted properly (should be much less of a problem now that EPS / latex moulding is very widely used), or if you're straight up missing material in key areas, then bad things can happen.
...

not to worry, i have ordered an endoscope already and intend to thoroughly check the frame once i have it in my hands. I will share here if i find any issues.

But i don't think it's brave of me to order one - the risk, at least in my view, is fairly small. And that, for me, is okay, especially given the prices we're discussing.
And if there's any issues, i have all winter to get this sorted with LC ...

Looking at maybe starting a build with this frame, have many gotten it yet? What is the "cheese" incident

it refers to the frame tiagosantos_ss received (here's his post including two pictures https://chinertown.com/index.php/topic,4309.msg65396.html#msg65396), and the quality issues. It had a couple of voids in the upper seat tube area. There was some back and forth with Lightcarbon but they ultimately agreed to send out a new frame to tiagosantos_ss.

I have put my order in a couple of weeks ago and i'm looking forward to receiving the frame early November. I hope, of course, that my frame will not show those kind, or any kind really, of QC issues.

Can anyone explain to me what Z3 quality is and all the other qualities?

Do all other sellers also use this notation?

To properly answer your question: this notion of different quality control levels in the context of Lightcarbon came out of a discussion Hambini had with LC people at Eurobike 2024. Hambini explains it in his blog here: https://www.hambini.com/bike-frame-manufacturing-standards/

Here's the main summary of the qc levels:

I think hambini made it up so he can sell more light carbon frames and get a kick back from them

man, knock it off. can you please engage in constructive discussion and not this sh*t. (you're also getting into libel territory here, if you can not back up your accusations.)

not sure if this is new (it is to me). LC is promoting the LCR017-D with '"Z3" Level Quality' on their homepage. This at least matches what Jim and Gavin have mentioned in the email correspondence I had with them.
Looks like people should then also be able to refer to that in case of any issues with the QC

On clearance, it's rated 32C, not 32mm, so you can run a 32C tyre on a wider than 32mm rim, your tyre will measure 32-33-34...mm and you'll be fine. If you're saying you want to run a 35C tyre, then it's a different question. On my LT268, i have a 34mm rim and a 32C tyre, and i have loads of space all around. the frame is also rated 32C.

Aah! learn something new everyday :-)
thanks for the clarification, this really helps!

even then, the restaurant should be given the opportunity to make it right.

There is a lot of fuss being made here about one frame. i think there will be QC issues but as long as the companies deal with it in the right way (in the end the customer should be satisfied with what they got), for me this is acceptable.
After all, to expect flawless QC at a fraction of the price for western brands is quite unrealistic.

On a different note: does anybody have the exact clearance for the fork and seat stays? Im wondering if 32 mm really is the limit or if i can push it a couple more mm if necessary.

Lightcarbons is being less than truthful...the fact is that QC  costs time and money but clear coat and facing of bottom brackets/ brake mount points shouldn't be optional dependent on price.

Not sure what you're on about. Where does it say that something regarding QC is "optional dependent on price"? Lightcarbon specifically states that they produce their frames to the Z3 standard.

I get the feeling you're on some personal crusade, that doesn't help anyone in this discussion. I'm all for constructive criticism, but your baseless accusations(as in, you provide no proof for your statements) are less than helpful and quite the distraction.

After reading every post in this thread and falling in love with some of your bikes, I decided to order this frame two weeks ago. But now you're making me doubt—will I receive a bad frame just because I ordered it before the Hambini video and didn't specify the code?  ???

In my communication with Lightcarbon i addressed this topic. Their reply was:

"No problem, we can get you the frame with Quality standard Z3 (actually this model are all produced in Quality standard Z3, what Hambini got is just a regular one from our mass production)."

Looks like there was no special treatment for Hambini, which however doesn't mean that issues with QC can't still happen ...

bummer.

I inquired with Jim regarding this new frame. This was his reply:

"Sorry, the ownership of this frame has been bought out exclusively. Please choose our other gravel frames, such as LCG071-D, LCG087-D (an upgraded version of LCG073-D, the head tube angle is changed from 68 degrees to 69.5 degrees, bottom bracket changed to T47-85.5)"

Looks like there is currently is no other frame available with this gravel/road mix or endurance geometry
