You won't find an actual chromed rim in 700c. It would have to be steel. Now I am sure you don't want to use steel. You can have aluminum chromed but I get a headache thinking about the price. What I suggest is starting with an alloy rims like a Mavic CPX 33


You will have to remove the stickers and buy a can of easy-off oven cleaner to strip the anodising.

Then you will need to use super fine (#0000) steel wool to removed the dark grey/black by product of this process... underneath the alloy should already be in good shape. In fact you could probably buff it with the steel wool and then get some Autosol or other metal/alluminum polish and polish out the rim to a very nice shine. The disadvantage is you have to always be sure to take some polish to it every one in a while to keep it bright. A felt or cotton buffing wheel and a drill will make this process a lot faster.

Or you could watch ebay for a set of super champion gentleman 81 vintage clincher tires and expect to pay top dollar. those were 700c polished alloy.

I think I know this bike.

EDIT: I would probably just go with the aeroheads like Rad.
