Can anyone give me some feedback on the GT Aggessor ? I'm a rodie and just love my rode bike , it is my baby. But I live in Colorado where it can get pretty cold and snowy and I would like to try riding this winter and thought I would get me a different bike for snow and cold weather riding. I purchased a GT Aggessor through a Schwinn liquidation sale. I just don't know if it was a good purchase. Any opinions about it ?
