Their key innovation lies in the \u003cstrong\u003eReverse Parabolic\u003c\/strong\u003e design, which moves the parabolic flex curve close to the foot rather than toward the tip.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical features and benefits\u003c\/h3\u003e\n\u003cp\u003eThis structural change was made possible by in-depth research into carbon lamination, which made it possible to increase the \u003cstrong\u003ethrust surface area\u003c\/strong\u003e compared to the hydrodynamic resistance surface. As a result, the MB002 deliver greater \u003cstrong\u003eelastic deformation\u003c\/strong\u003e, increasing \u003cstrong\u003epropulsion\u003c\/strong\u003e efficiency during the fin stroke.\u003c\/p\u003e\n\n\u003cp\u003eStiffer blades can therefore be used while maintaining the same physical effort as lighter blades, optimizing energy transfer and improving thrust without increasing fatigue.\u003c\/p\u003e\n\n\u003ch3\u003eStructure and materials\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBlade size: 874 x 195 mm, with total fin length (size 42\/43) of 980 x 195 mm\u003c\/li\u003e\n\u003cli\u003eMaterial: high-quality T700 carbon, for an optimal balance between lightness and mechanical strength\u003c\/li\u003e\n\u003cli\u003eConvex-profile water rails along the full length of the blade: reduce lateral turbulence and improve water channeling, increasing hydrodynamic stability\u003c\/li\u003e\n\u003cli\u003eWater rail color: black;
