WHY OFFERING 3 DIFFERENT TECHNOLOGIES?
Here are the differences:
Injection molded fins are manufactured using a metal outside mold. Our exclusive CARBO_TECH material —a proprietary blend of thermoplastic polymer and carbon fibers— is injected into the mold under extremely high pressure and heat.
Advantages:
- Since this material is softer than G10 it's the ideal choice for shorter maneuver side fins to ensure the necessary tip flex despite the short length.
Disadvantages:
- For fins longer than 12cm, injection molded fins are too soft to ensure a proper performance.
Best suited for:
Injection molded fins are the ideal choice for short side fins.

G10 is an extremely compressed block of prepreg laminated fiberglass sheets. This block is placed in a CNC milling machine to create the final shape and profile.
Advantages:
- Due to its high-compression G10 is extremely durable.
- Easy to sand, allowing to repair damages caused by ground contact.
Disadvantages:
- The high-compression results in a higher weight, which is noticeable with longer fins.
- Not stiff enough for longer high-performance freeride/race fins.
Best suited for:
G10 is the ideal choice for medium-size maneuver center fins.

This is the most sophisticated method of manufacturing a fin. It is based on individual pre-impregnated (prepreg) fiber layers out of carbon and glass. These layers consist of single fibers that are laid side by side onto a carrier film and then pre-impregnated with resin by a specialized supplier in an industrial hydraulic press. This ensures the ideal ratio between fibers and resin (not too much, to avoid excessive weight and ensure a perfect bond between the layers, and not too little, to avoid dry spots that can lead to breakage) even before it is further processed by our factory.
For these reasons, prepreg fins are at least 50% stronger in terms of breaking strength than the standard/conventional RTM technology, which uses dry fibers with "uncontrolled" resin addition.
Advantages:
- Flex and twist are not only determined by the length, width, and profile thickness of the fin design (as with G10 fins), but can also be adjusted by the arrangement of the prepreg layers.
- Lighter than G10.
Disadvantages:
- Not as easy to repair damages caused by ground contact.
- The most expensive way to manufacture a fin.
Best suited for:
Prepreg fins are ideal for longer high-performance fins from freeride up to racing.

PRODUCT DETAILS
Accessible speed — finally within your reach! Born from over 20 years of Freeride fin and board development by designer Dani Aeberli.
The F_RIDE (POWER) brings true Freeride excitement to every session.
Designed for riders who want one single fin that does it all, the F_RIDE (POWER) combines explosive speed, smooth maneuverability, rock‑solid control, and exceptional stability. Whether you're accelerating, carving through jibes, or pushing your limits, this fin gives you the confidence to ride harder and faster. Its medium rake ensures a more forgiving upwind experience and dramatically reduces spinouts — in light wind, gusty conditions, or fully overpowered.
Built using molded Prepreg Technology — the most advanced and expensive fin construction available — the F_RIDE (POWER) features individually placed carbon layers for perfect flex control and maximum reflex. This is premium engineering you can feel on the water.
The F_RIDE (POWER) is your gateway to faster disciplines like Freerace or Slalom, helping you level up without your gear becoming the limiting factor. Its balanced flex, consistent lift, and seamless acceleration make it the ideal match for any Freeride board — so you can focus on pure sailing joy, not battling your equipment.
