I have an XFusion H3 on my GT Force and I noticed one day the air can had turned almost 90 degrees. I was very hard to turn back. Now I pay attention and it still turns a few degrees each ride and takes all of my strength to turn it back. Is this normal? I can't believe there is enough rotational force to make the can turn while riding. Also does everyone else's air shock hold air indefinitely? After 2 days it goes soft.
