... Shimano XTR clipless pedals ...

May I know where you got these pedals from? What's the nut size: 15 or 16 mm?

I see, thank you for the clarification (his videos are quite boring and pretty watered, difficult to watch). Well, in this case, it's screwed up indeed.

Yes, I understand and have no problems with T47 as a standard, it's a good improvement.
I'm worried about mounting these small aluminum pieces in this particular (and some similar) case within a carbon matrix. Even fancy brands had problems with a proper adhesion between aluminum and carbon, and here, the contact surface is even smaller (compared to the most common bulky one-piece insert approach), and it's chinese (with quite random QC) manufacturing.

Regarding LCFS947 - pay attention to the seat post insert length, Light Carbon has quite retarded design here. I'm running their trail frame (LCFS958), and the maximum you can use at 19" size is 150 mm without any voodoo magic. I managed to install a 170 mm OneUp dropper (180 mm shimmed), but it was a bit tricky (see the pics below). The claimed seat depth is 200 mm, and in the case of 947, it's even 170 mm. I kinda have long legs (88 cm inseam being 181 cm), so there's more room for me. If you have a more usual inseam - keep it in mind. While running 958 in a bike park or whatever decent technical enduro or flow trails with jumps, I still would prefer to have an even lower seat.

As for the rest of the weight and price: carbon handlebar and rims, light pedals, and tires. I bought whatever 29" noname 29 mm inner width from AliExpress several years ago (around 450 grams, I assume), running with inserts + 791/2 Novatec hubs. No problems so far (I'm 75 kg fully equipped), but it's overkill. Next time, I will stay at 400 g. You can consider Goldix hubs as a light and cheap alternative to DT Swiss 350, but check reviews, some require a little bit of "optimization".

Front rotor, mate.

Any ideas why this outdated standard chinese frame is 850usd? The color schemes are interesting, but what else?

Another update from another store on aliexpress. FINTOWON BIKE this time with Winow frames. They have a similar to M030 (and M048) frame which is MF699. The guy told me that it was originally meant to be with a 52mm chain line and a max 36T chainring without magic.
