LightCarbon Gravel LCG074-D Micro Suspension Pivot Design

Do you have a link to those wheels?  That sounds like a very interesting spec.

These are the wheels. You can message them to discuss details. I opted for brass nipples, for example.

First pictures of my build. Still need to torque everything to spec, remove stickers/foils and clean bike. It's a size 58.

That bike looks absolutely beautiful.
Can't wait to receive my cremewhite/darkgreen frame and start building

I was just watching Peak torque and he he's ranting regarding toe overlap on the Yoeleo G21 (). The frame geometry comes close to the LCG074.

Does anyone have trouble regarding toe overlap with big tires? This could make me want to change from 52 to 55 in frame size. I'm 182cm so probably 55 is the best size anyways but a bikefit will hopefully give me a good answer.

Excuse by noob-ness here, but how is that suspension supposed to work if the bottom doesn't pivot at all?

[moo5000]

Answer is frame flex, by not making it rigid but flexible in one direction. check https://www.proxcarbon.com/prox-carbon-bike-gravel-frameset-micro-suspension-pivot-design-with-handlebar_p129.html.

No issues for me, but I have frame size 58 (and shoe size 45).

Thanks, I Will do some cross reference with my current road bike. Do you like your build? Do you feel like the pivot point is working while the frame is rigid in the same time?

My frame is custom painted now and I am awaiting delivery from China to Sweden.

Nice, I like the look.

My frame is also finished - since about two weeks. Lets see when it will arrive in Switzerland

Color scheme looks really good. Very clean.

So far I'm really happy with my build. No issues at all.

How good is it compared to other gravel frames? I don't know since I'm primary a road cyclist that has a hardtail MTB for the colder months.

So when looking at the comfort, I have the feeling that the rear of the bike is more comfortable than my mtb. However I don't know how much of that is due to the suspension pivot and how much to the flexing seat post.
I don't have the feeling that the system is giving me any issues that a flexy rear triangle might. Power transfer is fine as far as I can tell, no disk brake rub etc.

Thank you, your feedback from you own insight is highly appreciated. I also own a race and a hardtail MTB. Due to lower back problems i'm looking for a (relatively) more comfy ride. I'm hoping that the micro suspension does work but I'm guessing it's very minor, but all bits will help. As long as it does not have a big negative impact on driveability. Also seatpost and bigger tires/lower pressure will help for comfort. I just did a bikefit and the frame geometry will work good for me.

If there are more real world experiences from other people, I would love to know .

Frame arrived yesterday. Looking good!
I am flying to Africa today so just a very quick assembly late last night.
Tagoola XPLR wheels with 50 mm tires, and Shimano GRX. Toseek carbon handlebar and Trek gravel saddle.

I have received my frame four days ago.

The paint job is very good, but not superb. If you consider the price, it is absolutely worth it! I will upload pictures later.

After completing the assembly, I noticed that the headset bearing was slightly loose. I tightened all screws to the specified torque. Has anyone else the same problem?

Not me. When you say the bearing is loose, do you mean you feel the play when you hold the front back and put you finger on the top cap and push the frame forwards or do you mean the bearing fit in the frame is not perfect?
