Hi I am new here. I am looking at getting a Mt. Bike. I have a low end road bike(MSRP $550) but I don't ride it after I hurt my back. I put it on craigslist to trade for a Mt. Bike so I would have a more upright riding position and had an offer of a Trek 930 "SingleTrack". Not exactly sure what year but from what I have read online I belive it is a 99.
Here is picture of it http://xs123.xs.to/xs123/08051/trek_1910.jpg
Are these good bikes? and is there anything I should look for when I go look at it?
