So I tried this in the mtb forum and got no help at all so I figured I'd try you fine folks.
So I ride bikes pretty much very day, but other than a couple of old winter beaters I've built I have never owned a decent mountain bike. This is about to change as I just picked up a surly 1x1 frameset off ebay. I want to stick with a rigid fork as I'll be using the bike a fair amount for winter trail riding here in minnesota. Other than that I'd like to try riding some singletrack, but probably nothing too extreme. I'm aware that as a newb it prob would have been a better idea to pick up a cheap complete and then swap stuff out as I figure out what I like, but I ended up with a price on the frameset that was too good to let go. For the parts other than the frameset I'd like to end up below about $800, under is better but if there is a good reason to go over I can be persuaded. This will likely be mainly used for winter commuting and doing deliveries as well. I'm thinking of a single speed but I don't know much about IGHs. I've thought about an alfine hub, or maybe even a nuvinci360, but I don't know how durable they are. The last few winters I've used beaters, but not had nearly as much fun riding them as I have my better bikes. Any thoughts or advice would be appreciated.
Here is my very incomplete list of what I have so far.

stem? prob dimension or salsa
tires 1.5 or 1.9 studded that I have already
grips ? maybe oury, maybe ergo plus bar ends
