What Parts Dwould You Need To Fit This To A Tandem?

Hi,
Exact parts you need are going to vary depending on the tandem in both the general design and the way in which the current drivetrain runs. The basic parts you will need are: a set of cranks to fit to it, pedals (we usually recommend with toe straps), a length of chain (how many chains are needed will depend upon the bike and how you're fitting it) and a way to connect the opposite end of the chain to the drive system. The easiest way to do this is on a standard cross over drive tandem is to fit a normal drive side crank in place of the right hand captain chainset and fit a chainring to do this which will match the ring on the child's crankset, then use the new lengths of chain to connect the two. This is the system in use in picture 3.
Thanks.
