For 2013, Merida is introducing both new models and a new suspension design. VPK, Virtual Pivot Kinematics, which uses a unified rear triangle moving on a lower linkage and upper rocker arm to give the bike a virtual pivot point. This new suspension design will be on the the One-Sixty and One-Forty mountain bikes.
The video above shows two of the new bikes (and VPK) in early testing. The VPK bikes range in travel from 140mm to 160mm, with shock placement varying a bit between the two. The One-Twenty models use their more traditional A-Link suspension design.
Merida says VPK provides tight pedaling performance like a short travel bike but soaks up the bumps on gravity fed downhill sections with aplomb.
