Trying to help a friend with his new barn-find single speed 77' Ciao.
The rear pulley doesn't seem to be engaged with the transmission at all, like, I can spin the pulley all day and the rear wheel is effectively in neutral.
Is there a disengage on the rear hub somewhere? Or has something in the transmission gone wrong?
I've heard legends of a rod I'm supposed to pull or push on the rear hub to engage the transmission, but where it at though?
