RONIX Cheese Grater Button Tech Wakesurf Fin – Carbon

The Ronix Cheese Grater Button Tech Wakesurf Fin – Carbon is one of the most innovative fin concepts in wakesurfing, designed to give riders two completely different ride characteristics in one fin.

The standout feature is the perforated “Cheese Grater” design, which allows water to pass through the fin. This changes how the board reacts depending on the orientation:

• mounted one way → loose, playful feel (like a smaller fin)

• flipped → more grip and drive (like a larger fin)

This means one single 3.5” fin can feel like both a 2.5” fin AND a 4.5” fin, depending on your setup 

The fin is built with a carbon epoxy construction, making it:

• extremely stiff

• highly responsive

• very direct in power transfer 

Combined with Ronix’s Button Tech system, installation is quick and tool-free, allowing you to adjust your setup on the water within seconds 

Result: A fin that lets you tune your board’s personality instantly without changing hardware.
