I am into dirt jumping but I live in Australia so 200-250 is useless to me but anyone Redline just brought out a limited realese on their Double X Dirt Jumper. It is the regular Double X but comes with 3-piece cranks.

I have a 2002 Specialized Vegas TR-X and what the amount of abuse I have put it through. It is one hell of a bike.
