hello, i am not making the LR II, but i am using the jackshaft and truss from the plans. i dont do not always directly understand how these systems work together. for example. i now have 8 rear hubs to make my jackshaft with. i cant tell the difference between a multispeed hub and a freewheel hub, the thread look alike to me.

can anyone tell me ifs its alright to use a bmx freewheel on a multi speed thread?

2. i was making the freewheel of the jackshaft to connect to the 8 speed freewheel on the differential, but i now just realized i cant do that because of different chain sizes.

so, that means i now have to forget the bmx freewheel and use the single sprocket on a multiwheel?
