Hi, I bought the BC11 bottle cage together with the frame from LightCarbon. My bottle keeps falling out on small bumps. It seems very loose and does not hold the bottle. Has anyone else had this problem? Any solution? Thanks.

My experience after a few rides:

- seat post did slip, applied more carbon paste and it slipped again. Cleaned the seatpots , put a healthy amount of paste and 2 strips of plastic frame protection tape on the front and back of the seatpost where the clamp engages and it seems the issues is fixed. As other stated you can use any other slightly thick and tacky plastic.
- the LC integrated handlebars have a very short reach. If your position is dialed for a more traditional bar, order one with a 1cm longer stem. Also the bar drop is small, pretty easy to stay for a long time in the drops.

I have the same problem of a slipping seat post, I wanted to know which kind of strip of plastic frame did you use. Thank you

It looks like my front derailleur is slightly touching the tire (Chaoyang 700x38C, 24 mm internal rim). The tires are not fully inflated yet.
I suspect the problem is the derailleur, as I'm struggling to align it with the big chainring. Many say the LCR18 is very easy to assemble, but I'm finding it harder than expected.

I know this topic has already been discussed, but I can't find it again here in the forum. Is it normal to have this gap between the headset and the spacers? I still have to cut the steerer tube, but it seems very large to me. I haven't even installed the spacer of 0,7 shown in the picture, because I've already read that it can also be left out

Test ride review to come tomorrow.

congrats, that's awesome! I noticed you have maxxis Highroad, for me Is the first time I buy a set, yesterday I try to install them but It was so difficult to put them on. I am afraid If I get a flat during a ride might be a problem fix It.  Was it easy to install them for you?

I have ordered the standard BB which they offered to me, only 10$. Waiting for the frame and bb arrival, I have doubts about BB, maybe is really too cheap. I was wondering if it is possible to replace the bearing (with a ceramic ones) and if if it worth to do it. From lightcarbon replied "I think it's possible to replace the bearings ". What's your take on this?

Finished with 7.6kg incl. pedals.
Had to cut the seat post by ~25mm due to my short legs.

Congratulation very nice!! Quick question: what size is your bike?
From the photos it looks like you have quite a lot of seatpost showing, so I was a bit surprised to read that you shortened the seat tube by 25mm. It seemed a bit strange, so I wanted to ask you directly.

You can try to connect the leaver to the main battery using the wires provided. That way you can at least tell if there is a problem with the CR batteries/connectors or with the leaver itself.

yes using the wires it works, as I have also changed the CR batteries I think the problem is in the connection between the CR batteries. There is a problem but at least is not a fake useless...thank you

Should be an LED. If you push both buttons on the lever for a few seconds does the LED turn green?

yes the right turn green you are right! the left seems dead, but it is already something. did not about the both buttons. thank you

I'm waiting for my new frame to arrive, and in the meantime I bought an Ultegra Di2 groupset from AliExpress. I know this is slightly off-topic, but following this chat I understood there are many experts here I'd like a quick opinion. The shifters don't power on at all, even after replacing the batteries, and I'm starting to think they might not actually be the wireless ST-R8170 levers I ordered. The mechanism inside also looks mechanical. If anyone can tell me more from the photos— or share any tricks to test them, I'd really appreciate it.

My Ultegra Di2 just arrived today, bought on AliExpress. The shifters don't turn on at all — I even replaced the batteries just to be sure. I'm starting to suspect these might not be the wireless ST-R8170 levers they were advertised as. The internal mechanism also looks different, more like a mechanical unit. If anyone has experience with this or can tell me more from the photos, I'd appreciate it. I'm also open to any tricks or checks I might try to get them working.

Finally it's here, Banana for scale: https://photos.app.goo.gl/nT3KeXnNwRXrJr938

Just few first impressions:

• There is a lot of paint on my frame (520) -> 1125gr with front and rear hanger and box cover
• Rear brake mounting is not completely flush, i would say it's not flatted after the frame come from the mold
• The paint around the front brake mounting points looks not so great
• Paint around the storage box edge looks a bit awful (maybe a bit of sanding to clean it would help)
• Paint around the top of the headtube has also poor finishing edge
• Have a bit of yellow paint on the underside of the top tube, don't know yet if it's on or under the clear coat
• The pouch has a good quality, not a 1€ AliX bag, more like 5-10€
• The BB looks flatted and has nice clean threads
• Got a second LC Light UDH in the accessories bag for free
• Handlebar looks superb to me (but only had two AliX cheap ones for comperrison so far)
• The storage box cover is made from aluminium, at least it feels like metal and not plastic

Overall I'm surprised by the quality of the frame, the paint job was a bit difficult due to the two/three layers of paint for the crystal blue effect and the edge to the white parts.
By sides the few edges mentioned above the paint job looks great, no "bad" edges from blue to white on the whole frame/fork.

Will take few pictures from the inside with my 3€-HD-endoscopy-cam the next days.

And i have to figure out how to remove the red color on my tires...

congratulation, may I ask you which size of tyres you have?

I'm waiting for my new frame to arrive, but since my current road bike (cervelo r5) has some issues, I've changed my initial plan, I was thinking about turning my LCR018 into a more aero-performing oriented road bike, with the right groupset and wheels.
I'd really appreciate some feedback from people who already own this frame, or from those who know more than me about bike geometry and performance, to understand if the LCR018 can actually perform well as a race road bike.
Honestly, I'm a bit confused because I see many riders here in this forum using it more for kind of gravel setups and only few as AERO performing bike. Of course I understand I would never have a real AERO bike but how close it could be?

Finally an update, painting is finished and ready for shipment.
I had to change from the 400/100mm handlebar to 380/90mm, due to the ordered one is out of stock and would take another 2 weeks to make.

Also added the 15mm SB seat post for 50USD to my order, just to be a bit more flexible with the position and adjustment.
Here some screenshots from a video which Wendy send me.

did you choose to have the storage box cover in black color? Is It carbon?
