It has a typical Track bike bolt circle diameter of 144 mm (5-arm) and can only be equipped with one chainring (sold separately). It is an Octalink crank with 8 teeth, which provides more stiffness compared to square tapered systems. In order to save weight, the aluminium crank arms are hollow forged.
