Ronix Fin-S 1.8" NUB Surf Fin

Small Fin. Big Stability. Better Control.

Add stability and control to your wakesurf setup with the Ronix Fin-S 1.8" NUB Surf Fin. Designed as a smaller outer fin that complements a larger center fin, the NUB helps improve tracking, maintain momentum, and provide a more stable, controlled ride.

Built with a stiff, responsive carbon epoxy construction, this 1.8-inch symmetrical wakesurf fin provides support without overpowering the board's turning characteristics. Its compact profile makes it an excellent accent fin for riders looking to balance maneuverability with additional stability.

Featuring the Ronix Fin-S 2.0 tool-less mounting system, the NUB fin uses Spring Lock Technology with a two-stage engagement and removal process for convenient installation. Its floating epoxy construction also helps prevent accidental loss if the fin is dropped in the water.
