I think it's worth talking about hubs and rims separately but I build my own so I have the luxury of choosing exactly what I want and saving the cost of the build labour.

Hubs

If you have the budget go for the DT Swiss240. If you don't then the DT Swiss350 are very good also, that's what I have myself. They have the same internals as the 240's but are a bit heavier as they are forged rather than CNC machined. If you go for the centre lock 350's though they are only a fraction heavier than the 6 bolt 240's. They use a ratchet system in the free hub rather than the normal sprung loaded pawls and personally I think it feels better, more points of engagement and very quick pick up. These hubs are like a perpetual motion machine they roll and roll.

Rims

I used light bicycle wider carbon 29er rims. The ones they do now are the hookless type and are pretty much the same.

These rims are in the similar weight band to the Stans but are far far stiffer. Like really stiff. No compression on drops and laterally when railing berms they don't flex either. I found they slightly harsh to start but after getting used it I love them now as they are just so compliant and just go where ever you point them. I'm about 165lbs at the moment, they will be totally fine for how much you weigh. I know of quite a few elite and expert class XC racers that run these after running Stans rims and have never looked back. Some of these guys (the real whippets) even run the 28 spoke versions instead of the 32 as they are so strong.

I get though that it is a leap of faith to order them in from China yourself. They only take paypal though and to be fair paypal will pretty much always side with the buyer rather than the seller so there is protection there. I found the whole process very good though. The communication from the company was excellent and I haven't read of anyone having bad customer service from them. Warranties have been honoured where applicable. I think it's the mbtr forum that has a 100 page+ thread about Chinese carbon imports that has been running for a couple of years now and the feeling there is all pretty positive.

In terms of spokes I use DT Swiss competition and DT Swiss brass nipples.

I got them to go up tubeless very easily, using 1inch gorilla tape, Stans valves and Stans fluid. Didn't even need proper rim tape/strips. I have used them for about 5 months now; endurance racing, bikepacking (still stiff with the extra weight) and general trail riding.

I just put a pair of ZTR Arch EX on my rigid SS and they are rock solid so far. I am 6'2" and 195, so not a small dude.
I went ahead a put the standard NoTubes hubs on them. Setting up tubeless was so easy too, their bead lock technology works really well with even non-tubeless tires.

Warning, it took me over a month to get mine because of a back order issue. So call before you order to see if anything is back ordered.
