It was a MNT bike at one point back in the 80s and turned into what it is today.. I have a Techium Obsession with the space age glue, etc and all hanging in my garage. It's the first mnt bike I ever got and still rolls and shifts as good as new. It's lasted the test of abuse over the years.

I'd consider replacing the cables, etc with new. If you can do it yourself it's cheap. If you cannot use this bike to learn how to do it....just make sure to tighten things good.
