Houston Quadcore FLEX with Sci-Five


The Hubboards Houston Quadcore FLEX Core pairs the 2018 world champs winning shape with our newest core.  

QuadCore FLEX- Our New Core Utilizing our famous quadcore technology coupled with lower density poly pro. The result allows for the same incredible recoil and projection that the Quadcore gives you but with the functional element of flex used in heavy waves or cold water, or for riders who simplify enjoy & demand the dynamic properties of flex in their wave riding experience. 

Featuring our famous Sci-Five Concave bottom which greatly increases the board's overall speed, control and responsiveness. This happens as water is rapidly pushed through the 5 tight hydrodynamic channels creating cavitation which gives lift in the tail thus minimizing friction which reduces drag which equals increasing speed. WIth your rail engaged the Sci5 channels offer, heavy duty traction without sacrificing maneuverability. The five narrow channels, each 18 inches long are designed specifically to offer the freedom to spin, launch, and carve in and around the pocket with ease.

*ALL sizes come with one CFT Stringer (High-grade filament wound composite-fiber tube for increased board strength and spring-like recoil).
