why do you want it anodized? you cant see it and it adds extra cost. Aluminum doesn't corrode like steel, it doesn't matter if its bathed in rain or not.

Troy, if you are going to anodize, make sure they mask off the bearing assembly surfaces as it adds some small thickness to the material and may (or may not) throw you off your press-fit tolerance. (don't anodize with the bearing already pressed in for obvious reasons)
