I always relate to my cycling experiences like model rail road hobbyist, everything is a prototype. I am forever testing equipment, or methods in my cycling. that is what keeps my brain intrigued with cycling. Selecting the right tire for my bike is the focus that i am currently engaged in. My new bike came with Vittoria Corsa CX tires. I put 2,146.37 miles on these tires and they are shot. I had two flats last week in one day. I love these tires for the smooth comfortable ride, but I knew that they would not last long. I have a set of Continental Gator Skins on order and they will arrive on Tuesday. I am going to install a new set of Vittoria Corsa CX tires today so that I can ride this week. In the past I use to change my commuter tires for racing tires when I was planning a long ride on clean roads. I may start doing this now. I am also seriously considering trying out some 28 MM Schwalbe Maratho...
