I have fast bikes but because they cannot handle my shrek sized frame (6'6'' and ~330lbs)they are all worn down. I am not fat but even at the height of my fitness I was still ~265lbs. I usually get a year and a half out of a bike before it starts to fall apart but I have had the DT for over 2 years and it is as solid as the day I bought it. I guess I was looking to have the reliability of the DT with some faster performance. I realize that it may not be possible with the DT and I am ok with that because the DT is one hell of a bike!
