Description

The fixing is done by the heel of the fin in a box which comes to be plated on the higher part of the board. The originality of the system is that the screw is not integrated into the thickness of the fins, allowing them to remain thin and therefore reduce their drag.

The fin and the box sandwich the board, so it can keep a reduced thickness and all its flex.

The flex of the F-One Unibox 50mm is a unique feature for a twin-tip. The boards are smoother when sailing and also when landing jumps, they have less tendency to stall. The edges are more progressive.

The system allows to gain in glide and planning thanks to the thin asymmetrical profile and improves comfort thanks to the flex.

To respect the direction of the asymmetrical profile and install the fins correctly, they are color coded on their heel (red and green). This color is found in the female part of the boards.

A notch on the box has been added in order to attach a board leash.
