SPORT Bifins 2 Fiberglass

Regular price$420.00

Improved, ultra-responsive fiberglass fins, now created with the same material as the Competition Monofin 3.
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 freediving record-breaking Competition Monofin 3 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.

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 with a video attached of one of your dives for a recommendation.

SoftSuitable for smaller and lighter freedivers, and also for experienced freedivers with excellent ankle-driven technique. Softer blades are more economic in terms of energy consumption, although it mostly remains a preference among freedivers with more strength whether to choose a soft or medium stiffness.

Medium: Suitable for larger and heavier freedivers, freedivers with more lower-body strength, or for freedivers who needs more power.

HardSuitable for larger and heavier freedivers or freedivers with a lot of lower-body strength who use less frequency and more amplitude. Also favored by speed finswimmers.
