When I inquired about the frame back in March...

"LCR017-D is our latest bike frame and our frame designers also take the advantages of Cannondale SuperSix EVO. It's all-around bike frame as well.
Currently the LCR017-D (super light version) moulds are finished and in production.
The 56cm size is out of stock now and the manufacturing lead time is around 1 month."


Not sure if this email was intended just for myself. They will probably ask me to delete this since I know they lurk these forums.

EDIT: Maybe LC just meant they took design queues from the SS-Evo rather than actually produce it.

Your "Engrish" is not up to par.  They meant that the geometry is a match to the cannondale evo but their downtube delivers bus like aero.

Has anyone actually confirmed whether or not LC manufactures the SS Evo for Cannondale?

I was having a chat with one of my industry buddies who mentioned that since Cannondale is made in Taiwan, how could LC produce them? Which seems strange considering LC includes the SuperSix Evo in their marketing email to customers regarding the LCR017-D.

So either LightCarbon is spreading misinformation or Cannondale is using the produced in China but finished in Taiwan to be considered "Made in Taiwan." Or perhaps LC's is design is just different enough to avoid a cease and desist or copyright lawsuit?

According China Cycling Joe, Specialized frames are produced in China. Despite "Made In Taiwan" stickers on their framesets. None of this is my area of expertise so I'm curious what you guys think.

Never hear anyone claiming that LC produces Cannondale. Just some people in the begining of this thread said, that the LCR017 looked like a rip-off of the super six evo.

Guys, I need your help because this is driving me crazy ahahha. I'm assembling this bike now and I get an annoying creack when turning the handlebar to the left. I lost count on the number of times I've disassembled the handlebar, even switched position of the cables because I thought it was the cables snapping/switching one over the other but doesn't seem so. Any ideas where this can come from?
Sound is pretty much this just much less as i get only two snaps. It's like sth going outside and then inside again. Any ideas?

I think I'm  just missing taking the bearings off but not sure it can be from it as they are new and I put grease on them

Did you put foam on the internal cables?  Did you torque the compression bolt on the headset?

Yeap to both.

But I have only put foam in the downtube section, not on the headtube. Do you guys put there too? I felt that there was not much space in the headtube to put foam there and might end up rubbing. Maybe I can add it still with some bricollage as I have the brakes bled already and would rather not do it again ahah.

As regards torque is all as recommended by LC.

If you loosen both the expander plug and the stem (at the fork end), does the sound go away (or change)? If yes, it would speak to bits of the headset cap and spacer stack rubbing against each other or the frame.

I've installed mechanical group set with the internal cable routing handlebar. I routed the cables straight and without crossing. Also installed foam hose over every cable.

There is no noticable resistance in the steering but when I turn the bar more than like 80° there is a cable clicking sound too. Like one of the cables flicks over another cable and hits the frame or fork/steerer.

Not really a problem for me, since I'll never turn the bar that far while using the bike. Just want to share this experience with my first fully internally routed cables.

Thanks. That's exactly my experience ahah

But in any case good news. I was able to get rid of it. Just don't know exactly what did it. swapped the the shifting cables, cleaned the bearings from top, regreased and something seems to have gotten rid of this sound. My guess is on overlapping cables. Other than that seems fine. I have the hose dampner around the down tube. Now I was lazy to remove all the cables and rebleed the system. Let's see if the sound does not reappear

Thanks to all who tried to help

i reckon twisted overlapping cables finding position as you turn the bars, too

I see that best solution is really a Sram eTap ahahah. Well will have to be for the next build :)

Update on my bike LCR017-D.

Ride feels great. Still deciding on the final stack height (therefore I didnt cut the fork yet).
Frame arrived in a mint state, paint as well.
I've ordered a no offset seatpost and received a seatpost with 20mm offset. I've contacted LC and they will send a new seatpost with 0 cost to me, at least that was what Carol told me. No tracking no, so far.

General experience so far, glad with the quality, many room to improve and the transit times and QC on the shipment contents. 6,5/10

Looks like Hambini is building a LCR017

I am both excited for a Hambini video on this frame.  From my experience, if was a fantastic build and has been a great bike, and I would like for its internet cred to be maintained.

One update, while I don't have access to any sort of formal data, all my intuition and imperfect benchmarks on aero has been good despite the shape of the downtube. Riding side by side with others that I know their pm and my other bikes, this one has held up great.
