Description

This used Duotone Whizz SLS 850 front wing is a lively, pump-friendly foil for experienced prone, wake and wing foilers who enjoy flowing turns and linking waves. Its distinctive dihedral shape helps it roll smoothly from rail to rail, while the straight outline and low-speed-focused profile offer efficient pumping without making the wing feel locked into a straight line.

Why choose the Whizz SLS 850?

  • Responsive, surf-focused handling: the progressive dihedral design helps the wing change direction smoothly, making it well suited to playful carving on waves.
  • Efficient pumping: a straight outline with minimal sweep and an 8.5 aspect-ratio design balance glide and the ability to link sections.
  • Useful low-speed support: the cambered foil profile is designed to delay stalling when pumping away from a wave.
  • Compact 850 size: offers more agility for established riders than the larger 1000, 1200 or 1450 sizes.

Who is this wing for?

The 850 is intended principally for more experienced prone and wake foilers, with crossover into powered wing and kite foiling. It demands more take-off speed and control than a larger front wing. If you need easier lift for early progression or weaker conditions, consider the larger Whizz sizes instead.

Condition – used (actual item photographed)

Condition: Used, with visible cosmetic marks. These photographs show the actual wing offered for sale, both faces on a protective cover. The surface and printed graphics look generally intact, but there are visible fine scratches and rubbing, particularly towards one tip and around the mounting area on the opposite face. No clear major break is visible in these photographs. This is a visual assessment only: it does not confirm the internal carbon structure, every edge or the integrity of the mounting threads. Please examine the photographs carefully and request additional close-ups if required.

Compatibility and what is included

This listing is for one 850 front wing only, not a complete wing set. The wing is shown resting on a patterned protective cover, but whether that cover and any mounting bolts are included must be confirmed before purchase. There is no rear stabiliser, fuselage or mast included in the listing. The original Whizz SLS front wing is specified for compatible Duotone Aero AL, Aero AL 3BS and certain Fanatic aluminium and carbon fuselage systems; check your exact generation and mounting hardware before ordering.

Buying advice

Choose this 850 if you already foil confidently and want tighter, more expressive turns while retaining good pump performance. A larger Whizz is likely to be more forgiving if you are still building reliable take-off and low-speed skills.
