I cannot think of a "worst bike" I have ever owned. The bike I have owned, and still do, that I least like riding is my Orbea Avant. It is a nice bike, great looking, decent components, but I just do not like riding it. I had to try a CF bike, and this is the one I chose, partly because of the sale price when I purchase it. I do not like how noisy it is. The CF frame seems to reverberate whatever noise comes from the drive train, wheels, etc. It drives me crazy. I also find it rough riding and uncomfortable, I rode it yesterday, only 23 miles, and thought to myself that it just may be the last time I ride it.
