Re the Tourance, I know it's not very scientific, but when I got home after a 40 mile fairly spirited ride as soon as I got off the bike I put my hand on the back tyre...not particularly warm at all. With the Distanzia it used to feel hot hot hot! I'm only persevering with the Tourance as they are new and I want some money worth out of them, and like everything you get used to them. (Until I can justify a nice set of confidence inspiring Distanzia's that is!!) Steve
