I put the rear hub in it’s sleeve, in the rear frame tube, then cut that rear chain to length, and did a little test of the rear jackshaft-to-chain-to-rear hub. The chain running through the top tube, around the sprocket, and back through the bottom tube to the rear sprocket, with no rubbing inside there is awesome if not shocking, haha. The action is nice and smooth, very low friction.

I also cut the front chain to length, and checked the aligment etc of the front sprockets. Lookin good…
