FCS B5 Bonzer PG Clear 4 Fins

The FCS B5 Bonzer PG Clear is a four-fin side set inspired by the original Bonzer concept developed by the Campbell Brothers, designed to deliver an exceptional combination of speed, acceleration, drive, and control. Specifically engineered to work alongside the unique concaves of Bonzer surfboards, these fins help optimise water flow and unlock the performance characteristics of this iconic surfboard design.

The distinctive Bonzer Side Fin design helps direct water flow along the bottom of the board, contributing to efficient acceleration and excellent speed retention. Working together with the board's concave configuration, these fins promote smooth, flowing lines, powerful carving, and reliable hold through transitions and turns.

Constructed from Performance Glass (PG), these fins feature a solid fibreglass construction with a stiff base and subtle, responsive flex towards the tip. This combination provides a direct response under pressure while maintaining stability and control, even in more demanding wave conditions.

The set includes four side fins, with different dimensions for the front and rear positions, designed to complement the specific geometry of a Bonzer surfboard. The Clear finish completes the classic design with a clean, timeless appearance.

The FCS B5 Bonzer PG Clear is an excellent choice for surfers looking to experience the unique feel of a Bonzer setup, combining natural speed, progressive acceleration, and smooth carving with the control and responsiveness of Performance Glass construction.
