hey, if you already converted from 9mm to 12, what's another 8mm goin' up to 20? just stuff that axle in there. what's this metric stuff all about anyway, what is there something like 137millymetrics in an inch or something these days?
metric vs. the english standard may very well be the fall of the world's current superpower. we'll see if we can figure dem' dar' numbers out one of these days.

seriously though, nickabeans, it can get outta control round these parts if you come on here messing up the "sacred standard of bicycle numbers" when posting up questions, but no worries...
I believe you will need a new hub/front wheel. That is unless (slim chance) you currently have a front hub that is convertible between 9mm qr and 20mm thru-axle by changing the end caps. If not, you will have to upgrade hubs in order to put on a new fork.

You have to use a Saint rotor with the Saint hubs. However, the Saint rotor has a much narrower braking path than the Hayes rotor. This means the Hayes pads will ride on the rotor "arms." This will eventually lead to uneven pad wear and a variety of other problems. If you want to use those brakes, you'll have to grind and bevel the pads and check the contact area.

As long as the wheel build is decent, and you're a reasonably smooth rider (or don't go huge), those wheels should hold up okay.

I'm surprised the Bighit doesn't come with a 20mm Thru-axle fork and hub. What fork did you end up getting?
