The Utopia is called a dual sport by trek/Gary fisher so I guess it is a sort of hybrid leaning more towards a mountain bike. I am not sure what the width is on the Evoke 1. I know the Evoke RL comes in different widths but I am not sure about the version they put stoke on the bikes, it isn't on their web site separate. I will try and measure it later today.

My DH picked up the butterfly for me from a LBS I will have to ask them if I can try it out and still return it if it doesn't work. I am also going to call the shop where I bought my bike and see if I can try and WSD evoke today. Thanks
