Aaron Gwin and the Specialized development team introduces the new demo in its carbon version.
The brand new frame introduces both new wheels size and a new suspension design that uses a super pivot all around the bottom bracket (already seen on some 4x bicycle)
On the picture, you can see that the double rear triangle of the current Demo is not used again. The system switches to a more conventionnal 4 pivot design. The rocker goes far on the seat stays
Video says at the end that the Demo Carbon will be displayed on shop at the beginning of 2015.
