CETMA COMPOSITES continues to amaze with its countless creations, but for those looking for a one-of-a-kind long fin, we have created the Mantra Limited Edition design.
The Mantra Limited Edition is designed with six Swarovski XIRIUS crystals and a mirror logo that reflects a rainbow of colors when illuminated by the light.The MANTRA LIMITED EDITION is limited to just 100 pieces worldwide.

1) 100% IM7 carbon fiber is used.
2) The material used is 100% carbon prepreg manufactured with a hot melt impregnation system using micro reinforced tetrafunctional epoxy resin.
3) 3D-Tech. 3) 3D-Tech: CETMA COMPOSITES proprietary know-how produces parts with 0% void level, no defects and uniform matrix/reinforcement ratio throughout the blade at high pressure, high temperature and high vacuum.
4) FEM Design MANTRA’s blades are optimized by accurate design with finite element software (FEM), which allows for an optimized distribution of stiffness with the goal of obtaining deformations that ensure maximum hydrodynamic efficiency.
5) Signature model: developed in collaboration with Michele Giorgola, CWT bifin world champion.
6) DRS (Dynamic Resonance System) Innovative and unique to CETMA COMPOSITES, DRS means that the Mantra blades are designed to resonate at a certain kick frequency. Resonance is a well-known physical phenomenon that characterizes all structures. Simply put, when a structure is forced to vibrate at a frequency close to its natural frequency, the amplitude of the vibration increases very efficiently (low damping). Working by the distribution of stiffness along the blades, we have “tuned” the blades to a specific natural frequency. So when the blades are driven, by kicking, in a specific frequency range, what the user feels is very low effort and exorbitant thrust. This study was conducted by modal analysis using a laser vibrometer (LDV) to help design the stiffness distribution of the blades.
7) Dimensions: width 195 mm, length from bend 742 mm, bend angle 33 degrees.
8) Blade hardness available: super soft (XS), soft (S), medium (M).
9) Water rails. CETMA COMPOSITES water rails vary in height for higher efficiency.
10) Warranty: 2 years for carbon parts, 5 years with CETMA COMPOSITES foot pocket.
11) Awards and Prizes. Italian Champion 2016 CWT Bifin – 92 meters in 2:55.
