Just checked and Fox states "max 203mm rotors" are supportedIs the fork rated to use a 220mm rotor?
Unless you make your own adapter, the only way to do it would be to mount a 20mm adapter onto a 40mm adapter, if you do this check the pad alignment with the rotor, the pads should full contact with the rotor and never overhang it.

Alligator don't mention this XQ37 adapter and there doesn't seem to be any photos of this adapter anywhere.It seems that there is one adapter from a company called Alligator,
Although in the picture it shows PM 160 -> 180mm:
Will call them tomorrow to check.

Wondering how high is the risk to brake it...
I don't think there would be a problem with a 220mm rotor on that fork, I've got a old Manitou fork with a QR axle, it says it has a maximum rotor size of 210mm.2017 FOX Factory 34 Float, FIT4 3-position damper, E2 tapered steerer, Kashima Coat, Boost110, G2 Geometry, 51mm offset
I weight 240 pounds and ride enduro pretty much in the Alps, looking for some more surface for cooling down the discs in the long downhills we have here...
Just in case anybody stumbles across this thread someday, I can confirm the XQ37 is real despite the prior lack of photographic evidence.Alligator don't mention this XQ37 adapter and there doesn't seem to be any photos of this adapter anywhere.
The only place that mentions that adapter is that Italian shop which also lists it on ebay.
I don't think this adapter exists.
I couldn't find the Alligator version anywhere in the US. Here's a link to the Galfer SB003 +63mm adapter that I just ordered from their US site for a whopping $27. As a note I don't have Hope brakes. An adapter is an adapter as long as it clears my Saint caliper.Galfer has a 160-223. I use it on a Rockshox Pike with their Wave disc, no Problems.
