1x works well with a 26t ring. It spins an 11t out at about 18mph which is as fast as you ever need to go on a fat bike
1x would need new cranks (the SRAM X5 is 2x only), new derailleur since the X5 is max 36T, new cassette, new chain. RaceFace AEffect crank is 300g lighter than the X5 then you'd lose roughly 300g with the loss of the front shifter and derailleur. There'd be a slight increase in weight with a larger range cassette, call it 50g. That'd be somewhere in the region of £250 for 550g savings
That's without even considering going to 11spd or XD drivel. I think letting the current drivetrain wear out first might be in order.
Edit: knowing SRAM's predilection for odd BB standards, it's likely to need a new one of those as well
Looks like you've got your xmas present to Cath sorted then
Aeffect is 24mm btw

The 48mm was as wide as I could find but I'd searched for 100mm width which doesn't exist apparently. Didn't think to look for 75mm.
Phil - as I was typing the above she's just said that she doesn't want to go 1x. I've the AEffect cranks on my fat bike so knew they were 24mm. Looking at Surly's site the current Wednesday has gone 1x.

Update.
The front tyre wouldn't stay inflated, it would lose pressure over about 24hrs. A bit of (well a lot actually) of searching around and I found the reason, this was in a post on the MTBR forums from about four years ago! The rims (My Other Brother Darryl) have four sets of manufacturing "breathing" holes just inside the bead seat. These are tiny and almost impossible to see. I'd taped to these but not over them
Off with tyre, retape but this time going all the way across the bead seat, replace tyre. We'll see if it's any better. If it isn't then it's my taping at fault.
