Thanks everyone for your replies...I have cut back on the tension on the tire and have been trying to use Spokewench's suggestions. After that one morning where I could barely peddle, I have noticed an increase in my ability to work my gears more. I can't stand up when I ride...never have felt comfortable even out on the road standing. I am more of a "grinder" and I just grind up a hill. That is probably why I am so terrible at hills .
