Marin Bikes Team DH Frameset (2012)

QUAD DH Series: Refined through world class riders and tested on
mountains from Whistler to Bromont to Diablo, the Quad DH project has
been a labor of love and innovation. The new Quad DH chassis delivers
250mm of travel through a Quad Link 2.0 suspension system that features a
new low profile Y Link, to reduce linkage width while increasing
strength. A tapered 1 1/8-1.5? head tube increases front-end stiffness
and replaceable, modular dropouts reinforce the rear wheel and swing arm
interface for precise tracking through roots and rock gardens.
