I fitted SKS Bluemmels to mine at the weekend.
Drilled a hole in the guard for the fork crown mount. Could have then bolted it straight on but wanted it to sit a bit closer to the 38c slick tyre I’m running for road use, so used a Presta valve securing nut between the guard and the hole to space it out a couple of mm.
Biggest annoyance was getting the front guard stays to line up with their little receptacles. They’re angled to line up with the stays if those were bolted to a conventional eyelet near the axle, but the Arkose has its mountings higher up the fork legs to clear the disc caliper. Bending the stays into an S shape solved that, but it’s not quite as rigid as a result. Others may have found a better solution.
Rear went straight on in 10 minutes.
