The Inland Surfer Carbon Trickster Fins are designed for any wake surfers who want to feel that loosey-goosey sensation from a carbon fin while maintaining a real good snap. The Inland Surfer Carbon Trickster Fins are sold as a pair with 2-3cm screws. Get poppy and have fun with the Tricksters, but please remember to tighten them real well before you get your wake surf on.
