I have been running Continental Gatorskins on my bike. I put these on because I flatted 3 rides in a row. Recently it was recommended to me that I buy something a little lighter. My riding is training for or doing Century + rides. My preference is to do any ride with a lot of climbing. I live close to the Sierras and get a lot of opportunity to climb. I am 6'2" and 185 lbs.(if that matters) Can you suggest a tire and tube combo that would give me a good balance between weight and flatting? I guess I'm making an assumption that higher end tires are thinner and softer, but I have never used high end tires.
