I was under the impression that the standard frames were made in the Far East, while the LE frames were made in America (or was that just the earlier frames).
The catalog confirms my memory, 96 was just the Zaskar, 97 saw the LE with cnc dropouts etc whereas the standard Zaskar retained a seat collar and non cnc dropouts.
I think LE was also frame only “race” and the component spec was to be M900. I bought a turquoise frame in 92/93 in San Francisco and equipped it with M900. I sold it long ago but still have a 97. They are a fast frame and I still love the triangle design. It was cutting edge in its time and still a fun roll.
