Not trolling but why are you saying there is no QC?

Not trying to excuse this. I also hate when it happens especially in expensive products but QC is done at several stages. Maybe they need to add a QC layer here. I really don't know how the process of even putting it in the box working for them. If it's done by a machine maybe it could even be that. If its a manual process it can be sth else.

I'm looking forward to see how they deal with it especially since they seem to have no stock at the moment and waiting times seem to be around 2 months time.

The whole objective of a proper QC protocol is to ultimately produce products that are free from defects before they ship to the end consumer.   Everyone involved in the production process , from the initial order taker to the person packaging, should be another layer of QC and ultimately overseen by a department accountable for  quality control..

Hello everyone, I am a long time lurker of the forum.

I just received the LCR0017 and this is my first carbon frame.

The package was in excellent condition and the paint is realy good.

However, I am asking for advice as I am wondering if there is a crack on the downtube.
 
Indeed, there is a place where I see a small crack in the paint, and when I lightly press it with my finger it makes a scary cracky sound.
See on the video (https://www.youtube.com/shorts/O2SybUxEs6I), I really press lightly and it is the only place on the frame where there is this sound.
I find it weird cause the frame is straight out of the box, I have just put wheels on it.
I have no experience with carbon frame and I don't know if it is just the paint layer or a crack on the carbon itself.

I send an email to lightcarbon and I am waiting for their answer but I want to have other opinions

Just checked my lc17 at the same area and it seems likes it's very "super light" in that spot and probably only one or two layers thick of carbon sheet

LC website states 32mm max width

Hopefully LC will do better when it comes to painting frames by upping their QC protocol.

ahaha
I honestly think there is no difference both in weight and in aero gains (and I really don't care much about this as I don't race). Just more worried if there is actually any look diference or not

If I could do it again I would have gotten both 55s , front and rear

Nice build, thanks for posting!
Other than the paint, anything to report on? Holes that aren't round, tolerances that are off, brake mount surfaces that aren't flat, inside of the frame that looks crap, any of that at all?
Very helpful video btw. How boxy is that downtube in real life? depending on the video, it can look like the least aero shape one could come up with, but other times, it's not even noticeable.

The front and rear caliper mounts could've been faced to help with alignment.  The rear cutout for the derailleur hanger was a bit wonky and needed a little persuading to help it align to prevent it from binding up the axle when the set screw was tightened.  I choose black to specifically camouflage the overly boxy down tube.  Other than that the bikes been a dream to ride the first 400 miles thus far.

A couple of hiccups but Wendy from LC was able to remedy the issues.
