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 set, so check it against your board's twin fin boxes.

Deflow says the swept leading edge reduces turbulence for speed down the line, while the pulled-in trailing edge allows tighter bottom turns and more spring when surfing vertically. Twin fins are fitted as a matched pair, one near each rail, so check both boxes are in good order before fitting.
