He probado muchas aletas de algas y esta sin duda alguna es la mejor. Es muy rápida y la sensación al trasluchar es como la de una slalom. Las aletas de algas suelen ser rápida al ir tumbadas pero no hace lift y en los giros van demasiado sueltas. Esta no lo hace. Es genial.
Speed meets weed. No limits!
Tribal WEEDSPEED
Built for only one purpose: real slalom speed in weed conditions
Tribal WEEDSPEED Don't let weed slow you down!
WeedSpeed was built for only one purpose: real slalom speed in weed conditions. Fast, locked-in and powerful, it slices through weed while keeping full GPS potential alive. No drag, no spin-outs, just speed.
Most weed fins are a compromise: they clear weed but kill performance. WeedSpeed changes that. Based on our proven MK1 slalom outline, it’s re-engineered with rake and an optimised profile, tuned to shed weed cleanly without losing acceleration, control or upwind drive.
For riders who demand a GPS speed and race feel, even when the water is full of weed.
Why did we build Weedspeed?
Riders demand full slalom performance in heavy weed spots. The usual fins felt unpredictable or slow. WeedSpeed was developed to deliver what others couldn’t: 40+ knot GPS runs, rock solid upwind angles and acceleration that feels like open water even when weed is everywhere.
