Fast, Free, and Unlocked
This set bridges the gap between the blazing down-the-line speed of a twin fin and the hold of a quad, completely unlocking the tail of boards that can feel sticky or tracky with standard 4-fin setups.
Upfront Drive & Trim Speed: The oversized lead fins carry a wide base and ample surface area, generating immediate, effortless projection the second you drop in. You get that classic twin-fin skate and high-line squirt across flat sections without having to pump aggressively.
Loose, Responsive Pivot: Because the rear trailers are scaled down and pulled back along the rail, they don't produce the center drag or stiff tracking of a traditional balanced quad. On a squash tail or wider platform, the tail releases smoothly through the lip, letting you snap, slide, or redirect on a dime.
Control Without the Stiff Feeling: Instead of locking your line into a rigid track, the small trailers act like stabilizers. They bite just enough to keep shame-inducing blowouts at bay when laying into hard rail carves, yet stay out of the way when you want a slashy, free-wheeling feel in the pocket.
Ideal Wave Range: Built for gutless grovelers to punchy, head-high walls where you need instant acceleration to beat sections but still want the freedom to whip the tail around.
