We present the VBLABS AXIOM Competition Bifins Carbon Fins.
Shipping in Europe begins in June - first come, first served
Deliveries in Europe will begin in June
The fins of 2030 are already here today.
Built for competition, developed in collaboration with the top freedivers from Vertical Blue as a completely new performance sub-line. Lightweight feel underfoot and powerful energy return that carries you through every dive.
Less weight. Less drag. More you.
The first competition foot pocket designed from the ground up with separate left and right fits. It also features adaptive tension damping on the instep that works with your foot, not against it. The result is such a direct connection that nothing gets lost between you and the blade.
Engineered from First Principles
Developed by the top freedivers at Vertical Blue and the engineering team at Official Secrets. Inspired by the most efficient fins and marine life. Two years of uncompromising testing and refinement. The result: a fin built to break every record.
Technology
Caudal Keel Design
Inspired by the Caudal Keel. A tapered structure through the zone of highest oscillation reduces vertical drag, each kick cuts through the water more cleanly, and the blade generates direct, powerful propulsion behind you.
Autoclave Curing Process
Manufactured using the autoclave process, the gold standard in the composites industry. Carbon fiber is compressed under extreme pressure and a precise temperature profile, resulting in higher density and virtually no voids. The result is consistent energy transfer and faster rebound.
Footpockets, tailored to you
A one-piece foot pocket with adjustable instep padding and customizable arch position and height, designed to accommodate different foot shapes and personal preferences. Precise contact with every contour reduces slippage and energy loss, ensuring more stable and efficient power transfer.
High-Modulus Flex Pattern
Materials designed for the design.
To meet strength requirements, we use high-modulus carbon fiber—the same grade used in Formula 1. For the same weight, it offers about 40% more stiffness and springback than standard carbon fiber, without adding any extra weight.
