Duotone Finbox Carbon 30

Caring for your Duotone Carbon 30 fins

Rinse the fins and mounting hardware in fresh water after every session in salt water, then wipe them dry with a soft cloth. Salt and sand can build up around screw holes and threads, so it’s a good idea to regularly check that the screws and track nuts are still tight and move freely.

Washing and cleaning: Never use harsh chemicals, solvents or a stiff-bristled brush - fresh water and a soft cloth or sponge are all the carbon material needs. Let the fins dry completely before putting them away.

Drying: Dry the fins in the shade or indoors at room temperature. Avoid prolonged direct sunlight and heat sources such as radiators, as excessive heat can affect the material over time.

Storage: Store the fins in a cool, dry place, preferably in their original packaging or a fin bag, so they don’t get scratched by hard gear in your board bag. Remove the fins from the board for long-term storage and transport, and regularly check the screws for wear so you’re always ready for your next session.

What are Duotone Finbox Carbon 30 fins?

They’re an original fin set from Duotone Kiteboarding for twintip boards with a Duotone finbox. The set includes S-Bend fins in Carbon 30, along with matching M6 screws and Duotone Track Nuts.

Which sizes can I choose from?

The set is available in four sizes: WK 2.0, WK 3.5, FS 4.5 and FS 5.0. Choose the size that matches your current setup, or change the fin height to adapt the board to your riding style.

Which boards are the fins compatible with?

The fins are designed as spare parts for Duotone twintip boards with a Duotone finbox and are mounted with M6 screws and Duotone Track Nuts. Check your board’s fin setup if you’re unsure which size to choose.

What’s included in the package?

The package includes S-Bend fins in Carbon 30, matching countersunk M6 Phillips screws, and Duotone The Track Nut for installation in the finbox.

Why choose Carbon 30 over fiberglass fins?

Carbon 30 is a stiffer and more durable material that holds its shape better under pressure than fiberglass. This gives the board a more precise and direct response, especially during pop and landings.

How do I install the fins?

Place the fin in the finbox, secure it with the included M6 screws and track nuts, then tighten them evenly with a Phillips screwdriver. Check the tightness after your first few sessions.

How do I maintain the fins?

Rinse them with fresh water after use in salt water, let them dry in the shade, and store them in a dry, protected place in your board bag or original packaging. Avoid harsh chemicals and prolonged exposure to direct sunlight.
