I'm in the UK so mudguard (fender) manufacturers tend to be different. Also, racks might differ as the euopeans ones have to generally conform to a standard that doesn't apply to the US (standard rear light mounting brackets etc).

However, I did post on the konaworld forum and the techie at kona recommended Planet Bike fenders (which you can't get here). Also, Topeak racks have a range of disc-specific units.
