G4+/SR-71 ** synthesized / re-engineered *


Features single-to-double concave bottom for a drivey, predictable feel. Lower entry allows you to get into waves early and gain quick bursts of speed down the line. Good amount of tail rocker bending through the second half of the board makes for a tight turning, top-to-bottom board. Drives of the bottom like a dream and carries it’s speed through turns. An all around performance design that pushes back in waves large and small! A personal favorite.
G4-71 Synthesis
The drivey rocker and predictable bottom contours of the SR-71 with the outline and rails of the more swept back G-4+. A great wintertime and travel performance shorty.
- Ideal Conditions: Shoulder-high to overhead
- Experience: Intermediate to advanced
- Designed to: Lacerate on rail

When tigers attack:
Let me ask you this…if the most critical, powered up, styled out, one fin in, whole board out, frontside hack of the week happens outside the contest site, does it still happen? I know I know quite the philosophical question…yet it’s still a paradigm where the esoteric meets the material world in realtime…so consider your answer carefully.
