I have lost my tire changing virignity for real now! As I was riding the bike path, I was thinking that I would post a warning on our local website about all the plant debris from the trees overhead (thank you for the shade though!). While I'm thinking about it, to my heart and soul's fear and terror, I hear the dreaded hissing, from the rear tire no less. Dang! No bike mechanic with me this time. What a pain. A flat on the front feels like a gift compared to the back. I managed to get it almost completed and had to ask someone to help me get the wheel back on. I just didn't have enough hands to manipulate the bike, the wheel, the chain and the derailleur. I guess I need to practice in the comfort of my own garage so I can do it completely by myself next time. Because I'm thinkin' there will be more than a few next times!
