Our digital ship kit includes information on how to check for sufficient clearance, and how to mark your preferred installation position. Please take care in noting the size of the package used for shipping the crank (found in the ship kit information) as extra charges may be applied for unnecessarily large packaging. We ask that Shimano crank owners remove the two pinch bolts and plastic retention clip from their crank before sending it. Cannondale crank owners should remove the crank arm fixing bolt from the crank arm before shipping.
