ok so everybody i am going to purchase a new bike. in my mind right now i am highly considering a Trek 7.3 FX with disc brakes. like this one on thier site http://www2.trekbikes.com/bikes/bike...d=1328010&f=26 i looked at it and it seems very nice. kind of expensive. so i'm wondering what you all think about it. if its worth it, how good treks are and if i need the disc brakes. also any other helpful information would be much appreciated. thank you all in advance and i hope for some helpfull respones.
