Lightcarbon build LCR015 Decided to build a backup bike for my wife. Rear brakes were a pain but everything else went together perfectly.

Re: Lightcarbon: New LCR017-D (or Yishun R1058-D) When you compress this headset, the space no longer exists. I saw these comments and so I bought another set of spacer on Ali. By simply putting it down, there was no gap. Also, when I compressed the headset, the handlebars wouldn't turn anymore because they were too tight. So I came back with the initial headset which is well tuned. I'll be posting pictures soon. I'm currently testing the bike

Looks very nice  :D

Did you have the chance to ride it. If yes, how does it feel so far? Any problems?

Looking forward to get my frame and wheels.

Thank you.

The complete process of ordering with specifying paint, parts, and building has been a no issue (and pleasant) adventure so far.
Some really minor things are;
Tracking of the frame, a notice of a booked parcel and then nothing for 20days, and the last 1-2 days were packed with updates. Not a product quality issue.
Next minor notice, and im being quite picky now, is that the rear axle threads in place somewhat with resistance.
Hunch is that derallieur hanger and axle thread tolerances are not the same as the carbon parts.
To be honest, those are just small farts in a storm as comparison.

Did a initial 60min ride and pushed it a bit.
Im about 82-84kgs, Pmax of 1300w roughly on a super light frame, size 56 and my reaction is undisputed happiness.
Frame feels stiff and as per geometry of frame, right on target.
 
For a safety check of handlebar + stem check, I hanged my whole body wheight on the drops and jumped/rocked up and down. Solid as can be.

To summorize so far, _really_ satisfied.

@c74 - this looks like a really nice build.  Two questions. How still is the rear triangle / fork combo? Also, did you manage to see what the inside of the frame is like - any sharp edges or excessive creases?

Hi, sorry for late answer.
Don't quite understand what the "how still is the...", you mean stiff?  Anyways, for a superlight the frame is really stiff. As Im 80kg+ and bend quite a bit and feel no annoying flex to be worried about. For the non Super Light, I'd be worried it might be to stiff and harsh.
I combined the frame with 9velo's LV55's which are quite stiff,  the combo of frame an wheels, I simply cannot get the discs to rub on the pads whatever I do.  :)

About the inside, I have no small cam, so no, just eye balling down the tubes (also look at my previous pics in this thread) is it clean. Really clean. Frame is supposedly not build with bladders but some other technique, check LC's website for more info there.
The exit holes for brake lines, both on frame, fork and handlebar are somewhat sharp, but nothing that a fine sandpaper and just wiping the edge wont fix.
Bearing seats around head tube are equal in thickness all around, ie material between bearing seat and paint job on the outside.
Seats for wheels in frame is clean of paint overspray and edges are super sharp. Actually impressive at this price point.

Regardless of the price for the frame set in comparison to other products out there I think it is a really nice product.

Re: Lightcarbon: New LCR017-D (or Yishun R1058-D) Took me a bit longer to make this post.  Overall experience has been really good.  The fit of everything was spot on. Full build came in at 15.2 lbs without pedals (size 52).  For being that light, I am also surprised at how stiff it feels in accelerations.  My order was handled well and had great communication. I really like the color but it is more purple than I expected, but it looks great.  You can see in the sunlight it has the orangish chameleon, but the purple is the dominant color. Paint selection was LCB-02HS. Current setup is gp5000 28mm, but have a second wheelset with 32mm gp5000. One bummer is the width of handlebar options.  I went with the 40 x 110 handlebar and I have been running narrower bars and would have selected narrower, if available.

I will quickly address some of the items on this thread:
My frame has a drain hole under the BB
I will say that the layup feels pretty thin below the bottle cage on the downtube.  It is a larger tube size, but the wall thickness feels thin.
Brake caliper mounts are faced
Rear thru axle does require more torque than other frames (but doesn't appear to be any thread damage, so I don't know, not really an issue to me, but a previous poster described this).

I had to cut the seat tube to get my fit right, but just 1/2" or so.
I also ran into an issue with the seatpost clamp.  After riding I needed to adjust, and upon retorque the clamp to 6nm something with the pins that hold the bolt broke.  I have contacted LC and will update with how quickly they respond.  I am pretty sure their clamp is a tried and true design across other frames, so I am not quite sure. I want to tear it apart to see whats going on but it is kind of a captive part.

Re: Lightcarbon: New LCR017-D (or Yishun R1058-D) You will drive at more than 40km/h with this frame without any problem and maintain this speed. Concerning the wall, I confirm the thinness under the pressure of the hand. It reminds me of my Hyper wheels (Winspace), very thin too.

Re: Lightcarbon: New LCR017-D (or Yishun R1058-D) Yeah I am not too concerned.  As a whole, the frame seems solid and strong.  One of my teammates had a Trek Boone that you could press the middle of the top tube and it would flex.  I think it is the nature of a wide tube diameter and a thin wall.

Re: Lightcarbon: New LCR017-D (or Yishun R1058-D) Short update:
I did my first 50km ride today with best weather.

It was great and the bike feels amazing.

The only thing I have to get used to is the Free hub sound.
As it is a 36T Ratchet system, the sound is not "round". It's a little alternating which seems to be normal with ratchet Free hubs. But for me it sounds not so nice. Maybe I'll put more grease inside to get it less loud  :D

It's LCs C52DB-RD28-44C wheel set.

I'm being very picky here...

Re: Lightcarbon: New LCR017-D (or Yishun R1058-D) Basic issues like this make lc look amateurish. Brand new frame design but with no di2 port...

She said that she give this information to their engineer. So maybe if they think it necessary, they'll make some changes here too.

When I initially inquired LC about this frame, their response started with the following:

"LCR017-D is our latest bike frame and our frame designers also take the advantages of Cannondale SuperSix EVO."

If you're advertising your flagship road frame in this manner, how the heck did their engineers forget to include a proper Di2 port? Especially when my Yishun frame from their sister company included one. That is quite the oversight.
