This is the Scissor Jack. It is a 4.5 Inch travel frameset incorporating the floating shock VP linkage as seen in the DVP. The front and rear triangle are made of 4130 and the shock linkage is 6061 Aluminum. 

The VP link, which I have dubbed the Vari-link as it responsible for the variation in the shock curve, is now one solid piece of machined billet 6061 aluminum. This increases the stiffness in the rear end greatly over the previous design. The one piece Vari-link actuates between the two upright streamline tubes that connect the bottom bracket to the seat tube.

It will also utilize the idler pulley mounted to the tube perpendicular to the seat tube. It is located at the exact center of the rear wheelpath, at the most neutral point possible, for improved pedaling efficiency and practically no chain stretch.  

It has a solid one piece rear end with a reworked bearing cup design to improve stiffness and strength.
