Alternatively get a rack where you don't need to remove the wheel. These have a hinged arm that clamps onto the downtube, instead of a fork mount. Thule and most other brands make them - about the same price as fork mount.
Fork mounts are a hassle with 20mm axles as unless you've got a rock shox QR maxle, you have to muck around with allen keys etc everytime. Much easier and quicker to leave the wheel on.

If you want a really cheap one look at this.

Looks like two complete bike racks, but some bits missing on the bars, which presumably you don't need anyway. The racks are normally $150 plus each so $50 for two is very cheap - even if you need to replace some parts.

If you buy any Thule Rack where you have to remove the front wheel they come with an adaptor for 20mm. you pull out the locking quick release thingy and it slides though you dropouts and the adaptor (in place of your axle) and locks up just the same.

all true - but be aware that the thule model that grips the downtube has issues on some heavily formed frames - ok on my mates intense6.6, won't work with either my reign or his wife's stumpy120

hopefully we'll be seeing the newer 594 which clamps the front wheel out here soon (it's like the old super.g, beefier than the 530 and rated for 40lb bikes)

in reality though is sucks (as I found out when I got some 561s) - because the '20mm adaptor' is just a tube, works fine with a maxle/qr20 fork, but for something like fox's with pinch bolts it means doing up the bolts in situ on the carrier - bloody nasty

the hurricane is much better in that at least you get to do the pinch bolts up before manhandling it onto the roof

that system wouldn't work at all on a manitou fork with hex axle

why? the tube is functionally identical to a standard 20mm hub? it's just getting to the clamping system that's a pain

of couse trying to hold a 30lb+ bike in position with one hand and shove a thru axle home with the other is pretty dodgy anyway (really it's a 2 person job)

I see now.. the bits i've highlighted in bold had me thinking you replaced the fork axle with a 20mm pipe while it was mounted in the rack (not fitting the axle through a 20 mm inside diameter bracket as appears to actuall ybe the case)

do you have a roof rack already and just need the adaptor bit like the hurricane thing? or do you want a rack that is a 20mm mount?
I looked for a direct mount 20mm rack (one that didnt use any adaptor) a while ago and found nothing, thule do one now and from the breif look I had at one IMHO it was fiddly and could be had to mount a heavy bike by yourself, like Danose said.
I ended up getting an adaptor that I could attach to the bike on the ground and then get up on the roof and slip it into the QR roof rack mount.
If you want to borrow mine for a bit and see what you think of it Nordy let me know and I will get it up to you :thumbsup:
