Riber has made some significant advances to help you get the most from your SUP experience. Their new board attachment, known as “Pecfins,” is a key accessory for new and experienced paddlers alike. These removable fins attach to any SUP via a universal strengthening bar running across the middle for support. By gently rocking from side to side, these fins help to propel you forward while aiding stability. Easy to use for both standing or kneeling paddlers, Pecfins act in a similar way to bike stabilizers giving the user extra support and stability when needed.
