Good
ZTTO Dropper Lever/Remote - Pretty much as good as it gets, smooth operation.
ZRace Blade Crankset - Very high quality, the cnc machining is top notch, steel axle/shaft is heavier then aluminium versions but it wont break in comparison.
ZTTO M1 boost wheel hubs - High quality finish, light weight. The 56t ratchet seems to hold up to my probably less abusive biking compared to other people or I was lucky with getting two ratchets that align/engage perfectly (which is very important in DT style ratchets).
Cooma and Delt brake pads - Various types, works great. There's better pads out there of course but waaaaaay more expensive.

Bad
ZTTO Chainring protector/guide - I did not like it, super flimsy plastic mounting points for the protector. The chain guide is probably fine tho, haven't used it.

About time I'd share my 947.

If you look for an XC bike. Did you look at the FM936 or FM909 from Carbonda ?
Many happy people here(me included).
They are not on aliexpress, but by direct contact and trustworthy.

Would be my choice as well for a xc bike, nice modern geo and trusted by big name brands also.

Found this chainstay protector, the air one looks pretty decent.

There's generic downtube protectors on ebay/aliexpress as well. Nukeproof dissent protector kinda works also, but it doesn't cover all the way to the edges.

The bearings should be full compliment (usually called max in the bike world), that's the most important for frame bearings. The hardware store ones are usually with a cage.

Built a pair of carbon hoops using these, came out pretty light for being "all-mountain" rims, just over 1600g. The spoke lengths Ztto provided was pretty much spot on.
