I bought my TREK mountain bike in 1999 when I was living in Germany. After a few years of use I moved & it kind of got mothballed for the past 15 years for one reason or another. I am now back on the road and its pretty much like new after some basic maintenance.

My query is what model is it (receipt is long gone). Info that may help:

  • Serial number is: S99050362 (nothing on the http://www.vintage-trek.com/ looks relevant)
  • 27 Shimano gears with Deore LX M570 STi shifters; ( Silver with black decals colour; fairly light weight metal (aluminium??) frame.

It may be a model manufactured from about 1996 onwards but I bought it in late 1999. Any insight would be appreciated. I have trawled the web but the serial number on the frame has no hits.

    It is much more useful to show a photo of your bike. The serial number is usually useless. You normally have to ask the manufacturer. Commented Apr 11, 2021 at 13:14

    You have decals on the frame: what do they say?

Pretty much all the yearly Trek catalogs and technical manuals for the 90s and 00s are found here: http://www.vintage-trek.com/trek-fisher-klein-lemond.htm

There's also bikepedia.com and bicyclebluebook.com if you've got some idea of the model year and/or model number/name
