Hi I have a 2005 Gary Fisher Utopia that I have been using to commute on. I have a 10mi or so commute depending on which way I go and was going to try to speed it up a bit. I have the stock tires on the bike right now but wanted to put some more roadish tires on. I was thinking I could use some cyclocross tires but I am not sure what width to get. Does anyone know what the smallest width I could run on this bike is? Thanks for any help!
