Resolved 2 of the negatives... ran into another, but that's a squeeking BigRock crank issue so I won't bother you guys with it here.

I experienced this same issue with the saddle tilt on a recent ride. About 8 miles in, hit a bump, heard a creak from the saddle and thought I cracked a rail.  I did not, but the saddle was tilted and there was no using a multi-tool to get it unscrewed and put back in place correctly.  I was able to get it back to level enough by shifting my weight around as well, but it never stayed level.  All this moving around locked the screws in so tight, I stripped the heads trying to get them off.   That made for a fun time getting them out.  I had to resort to penetrating oil and lightly hammering in the hex wrench to get the screws loose.

I just pulled it all apart earlier this week, replaced the bolts with titanium M5x25mm hex head bolts and put it all back together again and torqued it to 8nm.   We shall see if it holds.

I'm still looking for any recommendation of a titanium seat post bolt if anyone has one that works for them.  The standard one has a soft head and I'm afraid it's going to get stripped.

Having said that, I do really enjoy riding the bike.  It's comfortable, relatively light, agile, and is responsive to accelerating.  Just a few small quirks to be worked out.

How has dealing with lightcarbon been to you guys? This isn't my first rodeo with direct chinese sellers but i'm getting a little frustrated. they tend to ignore half my questions and repeat themselves when i ask something else.

I've had a very good experience with them thus far. 
All communication has been with Jim Lee via Whatsapp. 
He is responsive, informative, and helpful.

can you share your height and inner leg? I am 172 and inner leg 80cm and wonder 50 or 52 will fit better

I also debated between size 50 and 52 and am glad I went with the 50. 
The standover height was a major factor given my shorter inseam.

Height 170.2 cm
Inseam 76.0 cm

Bike config:
Spacers under the handlebar - 40mm
Seat tube trimmed - 38mm
Crank arm length - 160mm
Handlebar stem length - 90mm 
Seat post offset - 15 mm

The fit feels very natural. I was expecting to have to play with things more, but the amount of tweaking to be done is minimal.

I have an extra seat post with zero offset and also another handlebar with 100 mm stem. 
I will play with these over time to see what feels best.

Hope this helps.

Ordered in mid-February and received in mid-May.   
Size 50
Just got it put together with SRAM Force AXS XPLR (1x13) groupset, and using LightCarbon Rims NRD28-450C (28mm outer width (21mm inner width) w/ undulating 45- 50mm height) and 32mm Conti GP 5000 S TR tires.

Why are you using a wide crank ? You can use the road version and have a nicer chain line.
I know nothing about the LC bottom brackets. I’m not sure why people are buying these over a regular SRAM T47 which works with a more common tool.

I'm still learning here.

When I was putting this together I thought the Force E1 1x13 system requires a DUB Wide crank (longer spindle) to achieve the required 47.5mm chainline and using spacers on both sides would work.   

I am now questioning this, thus my posting to the group.

I purchased the CEMA bearing because it seemed like a decent quality product for the price that LC was making them available.  I'm open to purchasing something else if that would work better.  I already have the tooling for installing the CEMA BB.

​I wanted to share my experience for those considering a frame from LightCarbon. If you are planning to order, I strongly suggest you double-check and insist on getting a realistic lead time before paying.

​Here is my timeline so far:
​Order placed: January.
​Initial shipping estimate: End of February.
​First delay: Pushed to the end of March.
​Current status: It is now late April, and the frame still hasn't been shipped.

​While the frame itself is finally painted, they now claim they don't have the handlebars in my size. It’s been a cycle of constant delays and moving targets.

​It seems LightCarbon is currently overwhelmed by demand and, unfortunately, they are not handling it well—especially when it comes to being transparent with customers about actual production and shipping dates.

I experienced a similar issue but ordered in mid-February.  The handlebars also delayed my shipment, but I worked with Jim to order an additional handlebar that was close in size to what I ordered in order to have the shipment sent out this week (I hope). Then I'll get the other handlebars I originally ordered later and will have to remove the temporary bars and install and wrap the new bars.

Of course, I paid for the extra handlebar and shipping, but that was expected.  It was a means to get the frame and wheels sent out sooner rather than wait another few weeks.

Hello,

Does anyone happen to have a photo of their LCR018-D frame/bike in glossy black? I’ve gone through almost all the pages of the thread, but the only black frames I’ve seen are either matte, raw carbon matte, or raw carbon glossy, but never glossy black.

Thanks in advance 🙂

I just received a picture of mine last week, which should be shipped out this week.

Imo you should pick the size 54, im 174cm but i picked the size 50 and there still lot of room for the seat post adjustment to raise.

What is your inseam where you selected the size 50?   Also did you select any seatpost offset and what length stem did you choose?
I'm pulling the trigger on the size 50 as well with 170.2 cm height and inseam of 76 cm.  I'm concerned however the stack won't be high enough relative to the size 52, but the standover on the 52 is a bit tight.
