Had a friend send me a "relatively gently used" Sachs Pentasport from the UK. I'm just a bit confused on the setup and can't seem to find much in the way of setup online. It has two shift cables, a "pulley" cable guide and another pulley guide as well as the clips to attach the cables,etc. It looks like I have just about everything I need and the hub and all looks to be in great shape (very mild surface rust, looks essentially unused). I'm just at a loss as to exactly how I should set this up and "tune" it in.
