So I got my Costa, finally, and have a question about what is supposed to be in the box. The picture, on the supplied manual cover, shows the bell, the weights and the lower plate. And also a metal shaft connected to the lower plate. I don't have that shaft part in my box. My guess would be that the shaft in the image below is the bike's drive shaft and that it's not part of the J.Costa? I just want to be sure...
