There is a whole lotta truth to the wheelset, tire, tube, etc...having an outsided influence on a bikes weight. A 1600 gram wheelset on a hypothetical 900 gram frame and 400 gram fork is not not going to have a noticable effect.
Now, I know it doesn't make for a hill of beans worth of difference in the real world other than bike feel. But, a set of Stans Grail CB7's weigh 299 grams actual and come in 28 & 24 hole options to ENVE's 24 hole only and cost 30% less than ENVE last I looked. 25-40mm tires covers a lot of possible uses. At a cost of 50 additional grams to accomodate a 38-60mm wide tires, We Are One Composites has 32, 28, and 24 hole Revive rims at $379
Berd Spokes are $8 each. Plus shipping each way. So what, ~$800 for the spokes & build service?
Extralite has some bangin' hubs that are stupid light and €600 for a set. But for a bunch of extra durability and less maintenance for the same cost, a White Industries set will set you back 200 additional grams.
All in all a disc tubeless wheelset weighing 950-1200 grams can be had for ~$2200 --Just throwin' it out there. You were going to swap out the OEM wheels anyway...Weren't you?
(Of course you were.

) So, get the bike that leaves the most budgetary room for an upgrade.
***Oops. They are only priced $1 apart.
