I am willing to bet that your right SimpleCycle. My train of thought had never taken me in that direction. Next time my sister is giving me sh** about riding a bike and getting loose I can throw that at her. (She's a runner and likes to make fun of my bicycle--not very nice). Thanx ladies for the laughs You know, I did not know until 2 minutes ago that THAT was a body part to worry about sagging!!! I guess I got that gravity thing right?!?
