C4 Carbon Blades L-1090 Apnea 25 (Soft)

Specific for freediving, featuring an hydrodynamic anti-turbulence flap.

They feature blades in two different hardnesses: 20 (extra soft), 25 (soft) and 30 (medium).

The surface finish of the blades is carbon fibre with a white decoration.

The blades should be paired with shoes with a black upper and a white sole (Sold separately).

The water rails are black and white.

 

• Blade Material: Carbonio HT15 – Betta design surface finish.
• Blade hardness: 20 Extra Soft, 25 Soft, 30 Medium
• Water Rails Color: Black / White
• Water Rails Progressive geometry. Overmoulded on the blades.
• Blade Dimension: 940 x 192 mm

 

These blades are specially designed and manufactured with a new progressive lamination of the carbon fiber layers, which is a strict technical requirement.

The lamination combines 4 different types of Japanese carbon fiber, specific for each layer, to optimise the reactivity and resistance of the blades.

The combined use of HT15 carbon externally (exclusive to C4), of intermediate areas with 7 layers of high-strength fabric and a calibrated combination of several unidirectional layers, produces a unique reactivity and an exceptional resistance to stress.

The resistance of these blades has been tested on our robot, specially designed and built by our technicians (link video piscina), with over 1.6 million complete cycles and a load three times the one produced by human strength.

The water rails of these blades are not glued but overmolded on the blades with a specific moulding process that fuses the plastic material with the composite. This innovative production process, which has never been attempted before on composite materials, was conceived by C4 technicians.

The plastic polymer used to manufacture the water rails, maintains elasticity four times more over time than normal NBR, the material which is commonly used tom produce the glued water rails. The overmoulding process is an industrial process, perfectly replicated, which avoids any separation that can occur on glued water rails.
