Okay I have decided to upgrade the forks on my 06 Giant Alias. Mys price range is 400-600 australian dollars. I use my bike for just about every tipe of riding but mostly for Small jumps (knee to waist high) and on most week ends i go for a light down hill (5 foot drops and such). I currently have rockshox j2's and they keep on bottoming out. what suspension would be good for me?
