Futures R4 Blackstix 3.0 Blue Small Thruster Set Surfboard Fins

Maximum projection, speed, and extended rail turns for lightweight surfers with the Rake R4 template in Blackstix 3.0 construction

Maintain brutal glide speed and link powerful rail turns with the Futures R4 Blackstix 3.0 Blue Small fin set. Meticulously designed for lightweight or promising young surfers (size S: 45 to 60 kg), this set stands out for its category Rake silhouette (with a pronounced backward lean angle), ideal for those seeking superior stability and sensational drive when making long arcs and carves on the wave face.

Blackstix 3.0 construction is Futures' premium technology for active speed generation in everyday conditions. By combining a rigid asymmetrical carbon fiber base with a flexible honeycomb core, these fins retain the force of your pushes and elastically return it at the tip when exiting a turn. Their performance is enhanced by the revolutionary Foil V2 (three-dimensional concave inner profile on the side fins), which hydrodynamically optimizes water flow, preventing the board from getting stuck in flatter or powerless sections of the wave.

Technical Specifications and Dimensions (Size S | 45 - 60 kg):

• Side Fins: 4.22" base, 4.37" height, and 14.22" area with V2 Foil concave profile for immediate acceleration and reactive pumping in soft sections.

• Center Fin: 4.22" base, 4.37" height, and 14.22" area with Symmetrical Foil for secure trajectory control and optimal tail stability.

• Blackstix Carbon Technology: Unidirectional carbon base that stiffens the lower structure of the set, combined with a translucent blue honeycomb core that dynamically flexes at the upper tip.

• Rake R4 Template: Stylish and laid-back silhouette that maximizes board grip when engaging the rail, providing control and fluidity in open-faced waves.

• Ride Number Speed Generating: Elastic flexibility specifically calibrated for lighter surfers to generate inertia and speed where other fins feel rigid.

Compatibility: This set includes 3 fins (Thruster / tri-fin system) exclusively compatible with single tab fin boxes (Single Tab / Futures).
