It's a '95.
They were never equipped with LX shifters or Sugino cranks.
If you want it original you need to find a set of White Industries cranks (ask some of the Marin guys, they know what crank it is) but equally important....you need to find some rare STI's for this one.
They are Shimano XT but they are called M738 (from '95). Normaly it's fairly easy to find M737's (from '94) and they look almost the same but have different indicators.
You would also need to find different grips and a set of Marin Lite bar ends (again, ask some of the Marin heads on this forum). The Titec post is original but I seem to remember reading a thread in here stating that there was a problem with the posts and that Marin recalled them, but I'm not sure about that.
....anyway....congratulations on a really great find. These are rare to begin with and finding one in this condition is a real strike of luck.
