+1 on the spokes! Never cared for the look of cast aluminum rims! Always loved the look of spokes and Old School white walls!
There is unfortunaly no replacemenet for hard work work and elbow grease when cleaning them.
Wesleys Bleach White and a few SOS pads work best on the white walls.
And an old toothbrush,soap and water followed by some polish works best for me.
