yeah, no surprise. but i'm sorry for your luck.
they have a great product, but since losing schumacher-usa as the u.s. distributor (for this same type of crappy service/supply, from what i understand) it's highly unlikely that people here will be buying from them directly. schumacher's pricing seemed a little better, and paul and adrian always made sure things were taken care of. it's really too bad.
on a technical note, perhaps you can acquire some spacers that you can either put inside or outside the hub? though 4-5mm is a bit excessive.
