Or I could possibly use a quad crankset for the Stoker to maintain the 72 speeds. Or, opt for a Schlumph crankset (about a $500 option).
As a note, the Greenspeed has the Stokers triple crankset shifter located on the Stokers handlebar. That way the Stoker has some control over gear choice.
And tandeming is all about communication. The Captain and Stoker must let each other know what they need to make the experience fun for both. Kinda like se*!
Losing a chainring means what??? I guess I don't know what a chainring is.
On a related note, is there a good primer on bike mechanics online? I am trying to get up to speed -- no pun intended--, but I've got a long way to go.
Thanks.
