Thanks to everyone who lended a hand to me regarding my issue with flats. I read through, took note & used the knowledge. Changed the tire, went for a couple rides and it's still holding solid. Perfect. Now my back axle is wiggling around.... Not much.. Just a little play when I wiggle it horizontally. That can't be good. :-/ Where the hay could that have come from? Am I gonna have to rebuild my back tire? I know I sound like a real newb but, I'm really trying to learn from the people who have knowledge of bicycles. I desire to have the knowledge to fix my bike all around because I can't fully trust LBS's. My experiences have not always been so good. But, I'm not at the level yet where I can replace the aid of a bike shop & what they know.
