Molchanovs SB2 Fiberglass are made with UHC Fiber, a high-performance fiberglass using over 50 times the pressure of other fiberglass long fins, and the same fiberglass we use in our PRO Monofin 4 Fiberglass.
Design updates to the blade include an improved layering of the fiberglass, using a “wave” layering structure that allows for smooth transition and even stiffness between the layers. This creates a more efficient and responsive movement throughout a kick cycle. Available in four vivid colors.
Our SB2 Fiberglass are of the same standard as most carbon fins on the market, making them an ideal choice for freedivers who desire quality but are not in the market for carbon fins.
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 bifins. For more information, see how to care for your freediving bifins and monofin here. Additionally, see how to travel with your bifins and monofin here.
A 1-year limited warranty applies. Please note that defects or damage to the equipment caused by improper or incorrect use or insufficient/improper maintenance and product care will render our warranty policy null and void.
Choosing Bifin Blade Stiffness
Blade stiffness depends on your height, weight, technique, experience, training goals, and blade size. Below are general tips on how to choose the right stiffness. If you are not sure, e-mail firstname.lastname@example.org with a video attached of one of your dives for a recommendation.
Soft: Suitable for smaller and lighter freedivers with less body strength and for experienced freedivers with excellent ankle-driven technique. If a freediver has more lower-body strength, they can choose a medium stiffness. Soft blades are more economic in terms of energy consumption, but require good ankle-driven technique to be effective.
Medium: Suitable for larger and heavier freedivers, freedivers with more lower-body strength, or freedivers who need more power. Freedivers who are heavier and have not trained to use ankle-driven technique should choose medium stiffness with a quad-driven technique.
Hard: Suitable for larger and heavier freedivers or freedivers with a lot of lower-body strength who want more speed and propulsion and are willing to use more energy consumption per kick. Hard blades require less frequency and more amplitude.
Production time for bifins take approximately 4 - 6 weeks depending on the volume of orders. If you need them sooner, write to us at email@example.com and we will check to see if we can accommodate your needs.
