Sizing Guides
The O'Brien Valhalla ST is the ultimate wake warrior model, designed off a traditional narrower profile, this water stick is designed to be zippy from edge to edge and is burdened with an explosive feel. Featuring O'Brien's renowned feather core mixed with a vector net carbon layering, the Valhalla ST model has a performance constructed core that is light to ride and smooth in transitions. The vector net layering adds a stiffness and strength required for those big airs and heavy landings. Combined with a progressive 3-stage rocker, allowing for plenty of pop while keeping smooth transitions wake to wake. On the underside of this board is O'Briens signature Delta base channels and a subtle spine providing that fast edge to edge response, evenly balanced with softer landings off airs. Make sure you get your annual weekend dose of wake fever with this blend of progression and innovation.

Rocker Line

  • Progressive 3-Stage Rocker – A 3-Stage rocker with a continuous element. A subtle curved platform between your feet, steps up to an increased curve in the tip and tail to improve consistency and provide a higher apex point on your jump

Board Flex

  • Energy Rating(1=Delayed/Stored Energy, 10=Instant Explosiveness) – 8/10

Core Construction

  • Feather Core – O’Brien’s boat performance core construction, reduces swing weight for more midair control and lighter transitions, while also maintaining its profile up the wake for plenty of pop.
  • Vector Net - A layer of carbon netting underneath the top layer of glass, this creates overall stiffness, maximising your torsional stiffness to reduce swing/transition time in your edges


  • Tip to Tail Sharp Rail – Slicing like a knife through soft butter, a full sharp rail gives you a precise cut through your entire edge from transition to wake
  • Thin Profile - Reduces swing weight


  • Bi-Axial Fibreglass – A 2 part fibreglass weave that provides strength to the board, but also allows for forgiveness and flex on landings


  • Delta Base – v shaped “Chevron” channels in the tip and tail of the board help to disrupt water and allow for a smoother edge, as well as providing hold through and up the wake
  • Subtle Centre Spine - Helps to pivot you into your edges and soften your landings


  • 4x 1.35" Quad Molded Fins

Rider Level

  • Riding Ability: Intermediate
