Mmmm... yummy Fox shoxs. I would definitely look into those (if I was in the market).

Being somewhat of a mountain bike slave, I'm usually of the mind that you ride it till it breaks... meaning, if I get a bike and it's components are ok for what I'm doing, I'll use and abuse till they quit or break. At least you get out of them what you can, and replace only when needed.

Now, on the other hand... I do like to have the best that I can afford. So, I bike shocks are usually one of the first things I replace.
