This must be a 2003 or 2004 bike, right? I don't see a Fuel 98 in Trek's archives after that.

It looks like it must be a 15.5" frame, not 16", based on what it says on the Trek web site. My current hardtail is a 16" frame, and I think it's on the small side, so I don't think this would work (but I can't find Trek's geometry chart for this bike so I can't check.)
