Top quality from Excel Japan! Shouldered Valanced Polished Alloy WM2 x 19″ 40 spoke rear wheel rim for Norton Commando 850 MK3 disc brake models. These are lighter and stronger than the stock chrome steel rims (great for racers!), properly drilled and ready to lace, and, while they are polished, they can be further brought to a mirror shine if you so desire!
