Certain Precor bike models have a hexagon shaped crank shaft which is no longer manufactured for replacement. This Crank Shaft Assembly and Crank Arm Kit can be used to upgrade from the hexagon shaped crank shaft and crank arms to the four sided (square) design that is now manufactured for replacement.
