The only reason I replaced my bike is because I wanted a new bike. There was logically no reason for me to do so though. My old bike worked great and served me well. But I had the itch to get a new bike and once I started looking around it was game over.

Funny enough, when I did buy a new bike, for the longest time I felt like I was cheating on my wife/girlfriend. I had this perfectly good bike (albeit apporx. 8 years older) sitting in the garage. Yet here I was, riding around one a new machine. That feeling left soon enough. But still, it was a strange feeling.
