I have two sets of Kenda's a pair of 700x25c that came on my Motobecane Track and they hold up good as a city tire but I can definently feel the difference when compared to my Michelin Pro Race 3s. The other pair I have are the 700x30c Kenda Kwicks on my cyclocross bike and I really like those, although I don't have much to compare them too, they're pretty light too! The ones that came on the Motobecane are super heavy feeling though.
