Hi, I am newbie and not terribly mechanically inclined so please bear with me. I attempted my first tire change today and was puzzled when the tube was much longer than the circumference of the wheel. I watched a youtube video "how to change a tire" and this didn't seem to be an issue. My wheels are 700x25 and the tube is "700x20/28 thin." What am I missing?
While I have you here--I got this flat after only 60 miles on my new bike... I originally wanted puncture resistant tires but the LBS sales guy said they were heavy and that I probably didn't need them. I know I need to learn to change a tire but I'd really like to do it as infrequently as possible. Are puncture resistant tires really that heavy? I am wondering what you guys think of Michelin Krylion Carbon Road Tires?
Thanks in advance for any help,
