I think they can....look like a 6 bolt bulb. if you take out the skewer you should see an allen key fitting in one end . clamp the other end and use an allen key to unscrew it. Then you need a 20mm kit from ebay/crc.
i think what he meant was the hollow axle will have a hexagonal shape inside it, allowing you to fit an allen key to unscrew it, drop Hope an e-mail with a decent pic of the hub, I believe they are quite helpful
Or scour their website
I have one of these.I havent tried to strip it but on other similar spacer arrangements its the disc side spacer that pops off.Its pretty tight so a pair ogf mole grips with fabric elastoplast on the jaws should pull it off.
