These MB fins are our best interpretation of the concept of traditional carbon fiber fins.
For the development of these fins we started from the design of the foot pocket. MB Fins feature the new 250 foot pocket, a direct derivation of the previous 300 model.
In MB fins, the major factor that increases performance is the new dedicated “Reverse Parabolic” lamination; a parabolic curvature which, instead of having the part with greater flexion at the top, it is near the foot. A complete reversal of concepts and an evolution of what our DPC (Double Parabolic Curve) blades had.
This dedicated lamination significantly changes the mechanical behaviour of the fin. The surface that generates the thrust is in fact greater than the surface that generates hydrodynamic resistance, thus producing greater elastic deformations and greater propulsion. The fin becomes a natural extension of the leg and not just a simple mechanical appendice on which to exert force.
There is such a big advantage that it is possible to use stiffer blades, therefore with greater performance, but using the same effort normally used with lighter blades.
Taking advantage of this feature we have raised the relative performance. A “+” has been added to the hardnesses. This is because, flexed in the hand, an MB 25+ is stiff and pushes as much as a standard 30 while weighing in the water like a 25. Restarts from the bottom, accelerations and speeds are thus higher.
MB fins feature new rounded section water rails that improve water containment on the blade and reduce water vortexes on the outer sides. The water rails, introduced by C4 for the first time in 1993, have always kept the water on the parts of the blade that generate the thrust. The MB feature a greater thrust surface and, for this reason, the water rails are integral, from the foot pocket to the tip of the blades.
MB fins are available in two versions:
The MB001, short 80cm blades
The MB002, long 90cm blades
The carbon blades all feature a matte surface finish.
