Pretty much a basic navigator 300. Looks like it's in good shape, so you did ok.

To explain a bit further into why it looks different than the others is that it could be a mid year change or they simply redid the appearance with a separate batch.

2001 was the only year the Navigator 300 was spec'd with an nsync fork 2000 was a trek brand fork, 1999 was a rigid. 2003 and up all have rst forks on them.

The headtube badge on it was used for a few years before they went to the round headtube badge, which was replaced by the current headtube badge.

The shimano set up on it is an older group that was made specifically for comfort/hybrids.
