The Megabass Spine-X 190 F is a segmented floating swimbait designed to comb the first layer of water below the surface. It features Megabass' Live-Wired system which exploits the shape-memory properties of titanium to provide realistic backbone tension to the lure's movement. Offered with three titanium wires, it is possible to add several at a time for a tighter "S" swim or to modify the number of wires to allow optimal custom adjustment of the Spine-X 190F's flexibility and tension to the situation and predator behaviour. The SPINE-X tail is made from an elastomer material that flexes dynamically to facilitate retrieve speeds from very slow to very fast with realistic action.
