This bike was just given to us yesterday. It's a Trek 4100. The frame is a little small for me. Notice the super elongatged seat stem.
The front derailleur needs some serious adjusting. I just used the smallest chain ring and I need to clean and lube the cables. Needs new grips (i'll probably just tape them for now) and the cover is missing from one of the shifters. Other than that it looks pretty good.
