It has a track bike-typical bolt circle diameter of 144 mm (5-arm) and can only be equipped with individual chainrings, which must be ordered separately. It is an Octalink crank with 8-speed teeth, which provides more stiffness compared to square systems. To save weight, the aluminium crank arms were hollow forged. With the FC-7710, you gain those fractions of a second that all too often make the difference between victory and defeat in the velodrome.
