Pair of Riverboarding blades 640 mm length E glass fiber
Riverboarding blades 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 blades are therefore only available in 3 stiffnesses. E glass fiber will give you a much higher yield than a plastic swimfin. On our Riverboarding blades you'll have specific water rails that protect the blade without reducing its flexibility and hydrodynamics. They can be fitted with Beuchat, Seac, Mares, Pathos and Imersion footpockets.
The 640 Series is best suited for slalom events. More compact, they will offer you velocity and maneuverability. Due to their smaller size, these blades 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. Compared to a plastic blade, fiberglass will provide you a better propulsion and less 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.
