In the drivetrain dialog box, we get to choose between chain or belt drive. When designing a tandem, it used to be that this choice would automatically apply to all segments of a tandem. In BikeCAD version 18.0, this is still the case. However, with each new tandem section we add, we can go to the Crank tab in the tandem dialog box and make a unique choice between chain or belt drive for that particular section of the tandem.
