I ordered from this seller and the frame arrived today. Here are my impressions. Ordered on Nov 17, shipped on Dec 8th, arrived on Dec 20th. Dark blue chameleon. I can post pictures of the frame, though I did not take any of the inside since it looked good (read below).

The finish both inside and outside is fantastic. Inside of my frame looks exactly the same as oralmaster's. Outside is flawless except for one small scratch (1x1mm) on the underside of the toptube. I am not sure if this is paint problem or it happened during shipping because the box was massacred to the point I had a heart attack when I picked it up. On the other hand, the frame inside was meticulously wrapped so it's hard to image it got scratched through all that padding. Anyway, it's practically invisible and nothing a bit of nail polish would not fix. No oversprays, caliper mounts nicely faced.

I nearly built the bike already and encountered no major issues. Both seatpost and handlebars were kind hard to slip into their place - not sure if this is a good or bad thing. I was especially fighting with the seatpost. Perhaps it was because of the di2 battery rubber mount is marginally bigger than the seatpost itself. The handlebars are stiff af, I have some muscles and I tried flexing them as much as I could and they did not move a bit. I encountered only one problem while building - the top of the D-shaped plug would not fit inside the fork because the walls were a bit thicker - a bit of sanding fixed this. Unfortunately I could not finish the build because I am a moron and bought T47 instead of T47A BB.

The weight of my frame (size 52) - fork uncut 446 g, frame+hanger 822 g, seatpost+clamp 220 g, handlebars 279 g, d-plug 35 g, headset+spacer 108 g. The weights are without thruaxles (60?).

Sounds like the quality is consistent, glad to hear the handlebars aren't too noodley someone was saying they were. Did you go for the highest tier option as well? How was the BB facing/threading overall? Should definitely toss some photos up!

Hey Team,

Regarding the Ostro replica, has anyone here successfully acquired a frameset from First-Class Carbon Store on Aliexpress?  If so, how long did the process take from order to delivery?

I believe OralMaster's white one up in the the thread is from them. I have one that is in the final stages and while he said 10-20 days till delivery, (Ordered Nov 24) same as Oralmasters actually with white and black. He replied promptly apologizing and sent a photo of the frame (nothing detailed) but said 7 more working days for it to depart it's in the final stages of QC. Fork was not in the photo but I could see the frame. I would say if you order in a month that is not December expect 20-30 days, maybe worst case 40 days.

I plan to take very detailed photos and get a snake camera that can look at the layup once it arrives. They charge a major premium and offer 3 "levels" of quality, I also chose the top one (6500RMB or around $1300CAD).
