I found a Zebra 12 speed at a local thrift shop a couple of weeks ago and since I wasn't familiar with the name didn't pay much attention to it. A couple of days ago I decided to do some research and discovered this thread. Long story short, yesterday I did a test ride and decided to bring it home. Frame is Tange 900 double butted cr-mo made in Taiwan. The other bikes listed in this thread have frames made in Japan. I wonder if the manufacturer turned to Taiwan for it's lower end frames in the 80's like some of the other brands (i.e. Centurion). It does not have a fancy head badge, just a painted flared Z where the head badge would be. Suntour a-3000 group. Araya rims. I'll post some pictures when I get it cleaned up.
