aluminum doesn't corrode the same way that steel does, and being that the phils are aluminum, you wouldn't have much to worry about. my rear D/A hub that went through three boston winters is still going strong, still super high polished, and the rim it's laced to is still in relatively new condition, except for a couple scrapes here and there from being under a truck...boston winters, BTW, while not as long as minneapolis winters are still pretty rough as far as salt and sand and other crap that the municipality slathers the roads with.

my hubs always ended up covered in a white film from the roads, but it just rubs off...
