Made from \u003cstrong\u003eT700 carbon\u003c\/strong\u003e, they deliver an optimal combination of lightness, elasticity, and mechanical strength.\u003c\/p\u003e\n\n\u003ch3\u003eReverse Parabolic Lamination Design and Technology\u003c\/h3\u003e\n\u003cp\u003eThe main feature of the MB001 is the \u003cstrong\u003eReverse Parabolic\u003c\/strong\u003e: the parabolic flex curve is positioned close to the foot rather than at the tip, thanks to advanced lamination studies. This increases the thrust surface area in relation to hydrodynamic resistance, improving the mechanical behavior of the blade and significantly increasing propulsion.\u003c\/p\u003e\n\u003cp\u003eThe larger thrust surface makes it possible to use stiffer blades while maintaining the same level of effort, optimizing finning efficiency and performance in the water.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Features of the Blade and Water Rails\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eBlade size: 806 × 195 mm\u003c\/li\u003e\n  \u003cli\u003eFin size, size 42\/43: 920 × 195 mm\u003c\/li\u003e\n  \u003cli\u003eMaterial: T700 Carbon\u003c\/li\u003e\n  \u003cli\u003eAvailable stiffnesses: \u003cstrong\u003e20 Super Soft\u003c\/strong\u003e, \u003cstrong\u003e25 Soft\u003c\/strong\u003e, \u003cstrong\u003e30 Medium\u003c\/strong\u003e\n\u003c\/li\u003e\n  \u003cli\u003eBlack water rails with a rounded profile to reduce turbulence, extending along the full length of the blade to improve water channeling and reduce edge vortices\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFoot Pockets and Sizes\u003c\/h3\u003e\n\u003cp\u003eThe MB001 fins are fitted with \u003cstrong\u003e250 foot pockets\u003c\/strong\u003e pre-shaped with a 3° angle, designed to ensure excellent comfort and smooth, direct power transmission.\u003c\/p\u003e\n\u003cp\u003eThe model is available in 7 sizes: 36\/37, 38\/39, 40\/41, 41\/42, 42\/43, 43\/44, 44\/45, ensuring a precise and secure fit.\u003c\/p\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cp\u003eThese carbon fins are specifically developed for \u003cstrong\u003efreediving\u003c\/strong\u003e and \u003cstrong\u003espearfishing\u003c\/strong\u003e, offering a perfect balance between stiffness and elasticity for efficient thrust and greater underwater autonomy.\u003c\/p\u003e","brand":"C4","offers":[{"title":"Super Soft -
