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.

Deflow gave this fin a wide base for a steady feel when nose riding and kept area towards the tip for drive through turns. Flex is kept to a minimum, because Deflow says too much flex in a fin this size can wash off speed in turns. Moving a single fin forward or back in the box changes how loose or stable the board feels, so try a few positions.
