SPORT Bifins Blades 3 Fiberglass

The Molchanovs SPORT Bifins Blades 3 Fiberglass strike the optimal balance between performance and value, making them ideal for freedivers who train, teach, and fun dive in the pool and open water. Updates include a new blade-layering pattern for more efficient finning, size-graded stiffness for balance, and a rounded blade angle for durability. Blades can be paired with standard-size SPORT Silicone Foot Pockets and can easily be disassembled for travel or swapped out for carbon blades.

Premium fiberglass blades
Premium 100% UHC fiberglass is more durable than carbon fiber blades and gives you flexibility and feedback from each kick, creating the optimal balance between performance and value.

Updated blade-layering pattern

Blades are consistently fine-tuned to be low-effort and high-propulsion, integrating our expertise in amateur and professional freediving athletes with our education system. The layering near the foot pocket now gives you a smoother and softer kick than previous fiberglass blade models.

Size-graded stiffness
Blade sizes now vary with stiffness so that length matches resistance. Soft blades are a little shorter for added maneuverability, while stiffer blades are longer for more balanced propulsion.

Rounded blade angle
The updated 28° blade angle now features a smoother and softer curve, adding another layer of durability to this critical area of the blade.

Easy assembly
Assembling foot pockets to the blades takes only minutes, making it easier than ever to switch to a new pair of foot pockets or upgrade to a new blade.

Minimalistic design
The new design is sporty and fierce while keeping the signature Molchanovs minimalism and style. Fiberglass blades are glossy black - choose from 6 bold accent colors.

SPORT Silicone Foot Pockets + SPORT Bifins Blades 3

These instructions are for assembling the SPORT Silicone Foot Pockets to the SPORT Bifins Blades 3 Fiberglass.

Please note that the SPORT Bifins Blades 3 Fiberglass are sold independently and do not include a mounting system. The mounting system is exclusively provided with the SPORT Silicone Foot Pockets.

Materials required for assembly

• Molchanovs left and right fiberglass/carbon blades
• Left and right SPORT Silicone Foot Pockets
• 2 screws for each foot pocket (4 total)
• Upper and lower mounting plates
• Phillips head screwdriver

Assembly instructions

1. Match the left and right foot pocket with the corresponding blade (marked on the back side of each blade).
2. Insert the blade gently into the slot at the front of the foot pocket and through the side reinforcements, verifying it is inserted correctly and slides in smoothly without force.
3. Align the blade by carefully adjusting its position until the blade’s mounting holes match with those on the foot pocket.
4. Position the upper mounting plate over the toe section of the foot pocket, verifying it fits into the provided space.
5. Begin hand-threading the screws into the holes of the lower mounting plate.
6. Place the lower mounting plate over the blade, aligning it with the upper mounting plate and the holes. Tighten the screws in a clockwise direction using a Phillips head screwdriver with an even distribution of pressure.
7. CAUTION: Secure the screws firmly, but avoid over-tightening which could strip the threads or damage the blade. Stop when you feel moderate resistance.

All equipment should be rinsed in fresh water after use and placed out of direct sunlight and heat. Do not place heavy objects on top of the blades and avoid placing the blades near sharp objects.
