Shown below is a more unusual variation--in this case, Colnago created an entirely new, six-arm crank that was engraved with their logo and Ermesto Colnago's name. This crankset was perhaps offered as a stiffer alternative to the standard five-arm cranksets made by Campagnolo. Whatever the reason, the design didn't last, and six-arm cranks today are as scarce as ... six-fingered bike mechanics.
