Ronix 3.5" Cheese Grater Button Wakesurf Fins

One Fin Design. Two Riding Styles. Total Control.

Customize your wakesurf board's handling with the Ronix 3.5" Cheese Grater Button Wakesurf Fins. Featuring a unique perforated design, these fins redirect water flow to create either a locked-in, grippy ride or a loose, playful feel depending on their orientation.

When the white-painted fin outline faces the outside rail of the board, the perforations redirect water outward, increasing rail pressure for stronger edge hold and more controlled turns. Reverse the fins so the white outline faces the center of the board, and water is redirected inward for a looser, freer feel through turns.

Built with stiff, responsive carbon epoxy construction, the Cheese Grater fins provide precise handling and versatile performance. The Ronix Button Fin mounting system allows convenient tool-less removal with the press of a button, making it easy to change your setup.

Available in 3.5-inch A Side and B Side configurations, these fins let riders fine-tune their wakesurf experience without changing fin sizes.

Riding Style & Fin Orientation

For More Grip and Control: Position the fins with the white-painted outlines facing the outside rails of the wakesurf board. This redirects water outward for a more locked-in feeling through turns.

For a Looser, More Playful Ride: Reverse the fins so the white-painted outlines face inward toward the center fin. This redirects water inward for a freer, more maneuverable feel.

Ronix describes the difference as creating a riding sensation similar to switching between smaller 2.5-inch fins and larger 4.5-inch fins, without changing the actual 3.5-inch fin size.

Compatibility
