MATERIAL: 100% Carbon MEGAFORCE T700 SHOVEL DIMENSIONS: 842 X 190 mm SHOE: left and right with adjustable closure COLOR BLACK SIZES: European 39/40 - 41/42 - 43/44 - 45/46 - 47/48 ASSEMBLY: with screws , easily removable WATER RAILS: VGR Variable Geometry Rails Official presentation made by Marco Bonfanti, owner of the C4. “The MUSTANG 3 fins were born from studies and tests that have taken me for over a year, with the aim of achieving a significant increase in water performance. The variants compared to the known Mustang VGR (which remain unchanged in the catalog) are in the new graphics, in the length increased to 842mm, in a different shape of the flap that has made it more robust to impact and a double-parabolic curvature of the blades in the water . The increase in performance derives mainly from the double parabolic curvature that best uses the movement of the foot, making the stroke more fluid in swimming than the VGR Mustangs. It is a development of the same concept that underlies all our products, that is the best adaptation of the equipment to human anthropometry, understood both as morphology and strength development. The attached drawings identify two areas facing a sectional plane that we want to neutral. From this neutral plane the parabolic curves of the blade depart towards the opposite ends. Thus the loads of water along the blade change during the transients of the movement and the result is greater continuity in the thrust, increased speed and lower energy consumption. More detailed technical explanations will then be provided through the usual information channels. The two similar models, Mustang VGR and MUSTANG 3 have reason to exist for a more aggressive kick with the VGR Mustangs and a more fluid and continuous kick with the MUSTANG 3, a double choice for our customers. The MUSTANG 3, like all C4 production, are made 100% with MEGAFORCE T700 carbon. I welcome the opportunity to reiterate that to date, after a year and a half of sales of C4 fins in MEGAFORCE T700, we have not had any break due to defects and / or construction defects.
