A huge thank you to everyone who shares their build experiences and ordering stories here-it’s because of this community that I finally pulled the trigger on a frameset from LightCarbon!

Early this summer, I decided it was time to build a fast, modern Di2 gravel bike-something capable of both quick weekend bikepacking getaways and ripping through local forest trails.

Here is my full breakdown of the timeline, ordering process, quality quirks, specs, and ride impressions. 

Ordering Process & Timeline

June 26: Placed an order for a size 55 frameset with custom paint and requested a 12mm offset seatpost. I submitted my colorway renders and got quoted 5,499 CNY (~$770 USD) for the frameset + custom paint, and $82 USD for shipping.

June 27: Received the digital paint mock‑up from the sales rep and approved it.

July 27: Production finished, and the frame was sent to the paint shop.

August 5: Received photos of the freshly painted frameset.

August 19: Shipped out.

September 4: Delivered to Moscow.

 

Packaging & Unboxing:

The packaging was solid-plenty of foam and protection, no shipping damage whatsoever. However, they sent me a 25mm offset seatpost instead of the requested 12mm offset.

 

Quality Control & Build Quirks (The Good & The Bad)

Paint job: First visual impression was incredible. The color depth exceeded my expectations, with a gorgeous metallic flake and subtle color shift in the sunlight.

BB Threads: The T47 bottom bracket threads were slightly damaged, so I had to get them chased at a local bike shop.

Brake Mounts: The rear flat‑mount brake tab was not faced properly and required facing to prevent caliper alignment issues.

Finish details: There were small clear coat chips around the rivnuts.

Everything else (internal routing, fork fitment, headset bearings) went together smoothly without any headaches.

 

A quick tip on LightCarbon quality tiers:

While my frame was already in production, I found out through one of Hambini’s videos that LightCarbon actually has internal factory QC/grade tiers: Z11, Z7, and Z3. They vary noticeably in price and manufacturing tolerances.

>Buyers looking for the absolute cheapest deals usually get Z11. Mine was built on the mid-tier Z7 grade. If I had known about this tier system beforehand, I definitely would have paid the extra premium for the Z3 grade. (I attached a comparison chart in the photos for those curious.)

First Ride Impressions

Right out of the gate, the fit is spot on for my dimensions (182 cm / ~6'0", 84 cm / ~33" inseam). On the road, the bike feels incredibly responsive under power and sharp through the corners. Clearance geometry is great too-zero toe overlap even in tight switchbacks. The frame and cockpit are definitely on the stiffer side, but with zero flex or noodliness when hammering on the bars, power transfer feels immediate. I'm loving it so far. Maybe it’s just the "new bike day" honeymoon phase talking, but right now I couldn’t be happier with how it turned out.

Still on the fence about the tan walls vs. blackwalls-keep them or make the switch? What do you think?

So this job has a history. Yes, I know that painting frames yourself isn’t something sensible to do, nor is it economically feasible. I like challenging myself, let’s put it that way. Don’t try this at home.

The first attempt went fine initially, except I used airbrush paint for both the primer and the candy colour. That did not hold the abuse of gravel racing and the paint started chipping. I sanded the frame down and started all over.

For the second attempt, I used proper epoxy 2k primer, sanded it up, passed a 1k metallic silver and went again with the airbrush candy. It worked fine on the tests I did, but on the frame the candy didn’t hold and stained like crazy. Again, I sanded it down. Lessons have been learned.

The final attempt I used a candy concentrate with the 2k clear coat on top of the primer and metallic silver, let it harden for 48 hrs, sanded it lightly and hot rid of some mild orange peel, placed the gold decals, and ran a very thin clear coat layer. It finally looks good now.

Next is building it up again.

Decal details: main logo Lightcarbon, the head tube lion is my zodiac (I’m not into that stuff, but it looks nice), the shell is my Compostela, not the oil company. The crosses are Andreas crosses, the symbol of my home town.

Paint details: 2k epoxy primer, 1k metallic silver (both sourced locally), Mipa CS90 with Stardust Candy Cyan Blue 06 and a top layer of CS90 deluded up to 15%.

Fast shipping arrived in about week in Germany. Very well packed and protected. Everything seems fine to be honest the carbon looks great. Paint job is alright it’s not like top notch but it’s ok. Tried to out the bearings everything went smoothly.
