The V-tach frame successfully combines long travel DH stability with quick North Shore maneuverability: increasing your margin of error allows you to push your limits beyond what you thought possible. The unique patented Knolly Four by 4 Linkage delivers excellent pedaling characteristics, neutral braking, no pedal feedback, impressive lateral rigidity and maximum tire clearance. Shock performance is maximized, with fully progressive ratios that permit extreme sensitivity while easily handling the biggest hits.
A full length seat tube and front derailleur compatibility make the climbs a pedal instead of a push. Adjustable geometry allows you to tailor your bike's handling to the most progressive technical freeride trails or to multi-hit high speed DH runs.
