Choosing fins

Check your board's fin box system before buying, as fins only fit the box type they are made for. Deflow does not state the base type for this fin, so check it matches your board's single fin box. Taller fins with a long base generally give more hold and stability, which suits nose riding and trim on longer boards.

Fin size is usually matched to board length and rider weight; a 9.7 inch fin sits at the larger end of longboard single fins. Moving a single fin forward or back in the box changes how loose or stable the board feels, so it is worth trying a few positions.
