New to the Blackstix 3.0 is the addition of two layers of unidirectional carbon, aligned at a 23º angle from the base. The angle of the ‘Uni’ controls the ratio of tip bend vs rotation as it loads up through turns. Running from base to tip, the ‘Uni’ adds support to hold more power without feeling stiff.
Working in conjunction with the ‘Uni’ are asymmetrical 12k carbon panels running vertically up the inside and outside of the fin. The inside panel runs completely through to the tip, along the leading edge. The outside panel only runs 2/3 of the way up the fin. This stepped reduction of carbon in the fin allows for more flex progression, creating a strong base and a snappy tip, resulting in a lively feel unique to the Blackstix.
To add one more layer of performance to the Blackstix, we use epoxy resin. Epoxy resin is lighter, tougher & more resilient than polyester resin. These features all play a role in making the Blackstix the lightest & fastest fins in the world.
As a bonus, epoxy emits 50-75% fewer VOCs (volatile organic compounds) than polyester resin, which means a decrease in harmful chemicals in our environment.
