Bioracer's head of development, Sam Ratajczak, explains. "The Ironman Hawaii is a challenging race in which not only aerodynamics or aquadynamics are important. The extremely warm, humid conditions are very often a determining factor in profit and loss. That's why we developed a suit for Bart that focuses on three areas: better gliding in the water, less resistance on the bike, maximum cooling during running.
As a basis we used a fabric with an internal graphene print. Graphene is a material that conducts heat and distributes it over a larger surface area, thus increasing heat dissipation. The fabric also contains small perforations that provide extra ventilation during cycling and walking.
During the swimming, Bart will also be able to benefit from the advantages of the Aquaracer fabric that is used in a number of strategic places in the suit. Aquaracer attracts air bubbles in the water and keeps hold of them. This creates a ball bearing effect and makes you glide better through the water while swimming.
The sleeves of the suit are made of Airstripe, a fabric that we also use in our Speedmaster suits for men like Remco Evenepoel, Tom Dumoulin and others. Airstripe comes in different variants developed by us, each one focused on a specific speed profile. The variant we use for Bart is ideal for speeds between 35 and 43 km/h. How we place it differs from suit to suit and from person to person.
We've tested fabrics, we've checked his position, we've gone to the wind tunnel at various times, and that's where we are now on the eve of the most important triathlon of the year, with the fastest triathlon suit in the world in our hands. We left nothing to chance. Neither did Bart. We’ve finished our homework. And he has too."
From the whole Bioracer team: Go for it, Bart! And good luck to all the Ironman participants!
