Thanks guys!
And right in the middle of the most complex machine this side of the Large Hadron Collider sits a Super Record derailleur!
Is that a good thing?
The 7 sp freewheel is NOS so I used stuff lying around. The "NEW" trike will have a Shimano cassette freehub mounted on the diff. Looking forward to Dura Ace 8/9 sp setups!
is there a sliding spline somewhere in that drive shaft to handle suspension movement
Under the rubber boot next to freewheel, sliding ball coupler...similar to the inside of a inboard CV joint on a FWD car.
