Flying Diamonds 10" CJ Parallax Single Fin

The Flying Diamonds CJ Nelson Parallax 10" Center Fin is designed to deliver speed, control, and effortless trim for longboarders who love glide and flow. Created by CJ Nelson in collaboration with Flying Diamonds of California, this fin was developed specifically for the Parallax line of boards but performs beautifully across a wide range of classic single-fin setups. Its medium rake and refined flex pattern give you smooth direction changes, incredible hold, and acceleration down the line.

Performance and Design

The 10” Parallax Fin features a narrow tip and fuller base to provide the perfect mix of stability and responsiveness. It’s built for surfers who value speed through trim and graceful control during turns. The progressive flex allows for clean energy release out of each carve, while the upright outline promotes faster pivots and easier stalling for nose rides. Ideal for mid-weight to larger surfers or anyone riding longer boards that thrive on down-the-line flow.

Crafted by Flying Diamonds of California

Flying Diamonds of California works alongside elite longboarders like CJ Nelson to produce performance-driven fins that balance heritage design with modern feel. The Parallax 10” embodies this commitment — giving your board a responsive, connected feel that enhances your surfing in every condition.
