I would also wonder if the bike is too small. THe seatpost is waaa-aay out of the frame, and you seem to have changed the bars and jacked the stem all the way up to keep it high enough.

Just curious - do you ever feel like you have too much pressure on you hands, or do your hands go numb often whey you ride?

Edit: Also, seems like a lot of trouble to go through for a 16 year old Taiwanese made steel frame.
