Looks great, what seatpost is that?

Lexon Carbon Seatpost 27.2mm, 5mm offset, 350mm length
https://www.aliexpress.com/item/1005006955238530.html

I chose it hoping that it would be more compliant than my other carbon seat posts, but it's actually one of the stiffest seat posts I've got!
It's very nicely finished, and I only paid £39 including delivery.

Finished my build, pleased with the result!

Frame: SPCycle G028 size large, in metallic green
Wheels: CSC 5.0 50mm deep, 40mm external, 32mm internal
Tyres: Thunder Burt 2.1 tyres (which measure up at 55mm on these rims)
Shifters: SRAM Force E1
Derailleur: SRAM Rival XPLR 13-speed UDH
Cranks: SRAM Force D2 road cranks with Quark spindle power meter
Seatpost, bars, and stem from AliExpress.

Weight is 8.47kg with pedals, but without bottle cages, Garmin mount, or rear light.

I received my G028 yesterday, and have started to inspect / build it up.
The QC was reasonable: the BB and brake mounts were faced adequately, the headset bearing interfaces and fork were clean.

There are two issues I've found so far:

• The seatpost clamp wouldn't fit due to paint overspray and some excess resin. Without the seatpost clamp, a 27.2mm seatpost fit just fine, but as soon as the (fully expanded) clamp was installed, it was too tight to fit a seatpost. I removed a small amount of material with a dremel, and it's now a perfect fit.
• There are several small paint defects, from a hasty paintjob. These are fairly minor and for the price I paid I'll be able to live with them.

Frame and Fork Weight
My frame is painted in green metallic, and is a size large. The frame weighs 1271g with no accessories/hardware, and the fork weight 502g with an uncut steerer.

Chainring clearance for road cranksets
I've fitted a SRAM Force D2 road crankset (standard road / non wide) with a 44T chainring (with a 3mm offset, rather than the standard 6mm), and with a 2mm spacer there's plenty of clearance to the frame (±6mm).

I'll be building up with SRAM Force E1 shifters, SRAM Rival E1 XPLR 13-speed rear mech and SRAM Rival XPLR 13-speed 10-46 Cassette, and various components sourced from AliExpress (seatpost, saddle, stem, bars). I have a carbon wheelset from CSC, 32mm internal, 41mm external, 50mm deep, 54T Star Ratchet, steel spokes, 1450g.

I'm expecting a final build weight to be ±8.75kg, and will post pictures when it's complete.
