I haven't seen any covers. There is a big tire kit that has a new chrome hub included and others have had their's chromed. I will be taking mine to the chromer with my wheels, fork tubes, and kickstand as soon as the first snow flies here in Colorado. I'm sure someone will eventually come out with a cover, but I just can't imagine living with it silver after my wheels are chromed so I'll just bite the bullet and have it chromed...unless a cover comes out before I tear the bike down?
I would also be interested in brake caliper covers front and rear I can just imagine how great those calipers are going to look with chrome wheels as well!
