Bridgestone Potenza Arumi

This simple four-spoke was released in 1979 as the Zona Special Potenza in 13 and 14 inch diameters.  With cast construction, 14 6J wheels weighed in at 6.0kg.  Gold was the only colour offered.  In 1981, when the Zona line up was revamped, the wheel lost the beetle on its centre cap, and was simply renamed to Potenza Arumi (aluminum).  With a max size of 14 6.5J +5, the wheel is often overlooked by enthusiasts today but at one point in history was a very popular option.
