Riverboarding bifins 640 mm length C5 carbon
Riverboarding bifins for distances from 50 to 1500 meters. Flexibility will be preferred when the distance increases. For a same stiffness index, a short blade will be more rigid than a longer one. These fins are therefore only available in 3 stiffnesses. On our Riverboarding blades you'll have specific water rails that protect the blade without reducing its flexibility and hydrodynamics. Thanks to the contribution of C5 carbon, bending's return of the blade is highly efficient. This pair of high performance and durable fins will become the perfect match for long workouts. A reference for the most demanding finswimmers for years. You can choose a branded closed-heel footpocket or a custom-made open-heel footpocket. This one frees the rotation of the ankle in all directions and thus increases the finning's amplitude and the efficiency thanks to a more precise foot positioning on the blade. Finally, it facilitates direction changes. It takes a little time to get used to it.
The 640 Series is best suited for slalom events. More compact, they will offer you velocity and maneuverability. Due to their smaller size, these fins are only available in 3 stiffnesses. For the same hardness grade, the 640 fin is stiffer than a longer fin. To choose the right stiffness, it is also important to take into account your body size and your level of practice. This C5 carbon blade is ideal for swimmers who want to significantly increase their performance and reduce fatigue. To choose well, use our help: 'which model and which stiffness for me?'.
PRECAUTIONS FOR USE :
Your fibreglass or carbon blade can break :
- If the fin is stuck (the end of the fin is stuck, all the weight is on the blade and it cannot bend) => Do not push off with the blade on the bottom, the side of the pool or on the bottom of the water
- If you jump into the water with the blade parallel to the water.
