The 2010 attack trail replaces the wolf ridge. Prior to that the attack trail was a more aggro version of the wolf ridge but essentially the same frame, specced with lyrics and hammerschmidt, etc apparently the geometry was the same as the wolf ridge, and the frame was tailored to compensate for the taller fork. Or so I have been told, although this might just have been someone waffling at me as the one I rode felt much slacker than a wolfridge.
The current attack trails (2010 onward) are slacker, stiffer with tapered headtube, shorter links etc in comparison with the wolf ridge. Additional hydroforming on the main tubing. Think the seat angle is half a degree steeper too, with 150mm travel as opposed 140mm. Oh and the graphics have s sh**ty bear spider web thing happening.
