Hit your performance potential for triathlon or time trials. Front to back, every curve and shape of the new Attacca TT is fine-tuned through Computational Fluid Dynamics for optimal aerodynamics. Wind tunnel tests prove that it provides an aerodynamic advantage in various rider positions and at different wind angles. On the road, Attacca TT delivers unrivaled fit and comfort for Team Liv-Plantur pros and everyday competitors.
From the crown of the helmet toward the rear, two dimples—one on each side—help channel airflow toward the tail. CFD simulations and third-party wind-tunnel tests show that the dimpled shapes, combined with the shortened tail, optimize average aero performance in various rider positions and wind directions.
CFD and wind-tunnel tests prove that the short-tail design of the Attacca TT performs best in real-world conditions when winds shift and a rider’s position is dynamic rather than fixed . The result is improved aero performance, especially for longer distance triathletes or TT riders.
Strategically placed AeroVent ports—four large radius intake ports in the font and one large exit port in the rear—maximize airflow through the helmet for superior ventilation. The precise shape and position of the intake ports are “drag-neutral” to help optimize aerodynamics.
The AeroVent ports pull incoming air through the helmet and stream it through deep internal channels from front to the back. The result is head-cooling ventilation that helps regulate temperatures during hard TT and tri efforts, while maintaining superior aerodynamics.
CINCH PRO FIT SYSTEM
The perfect blend of security and comfort. Cinch Pro™ offers optimal coverage by cradling the occipital bone for full protection, support and comfort. Large scoop-like paddles protrude outward to cradle the head.
ELEMENT STRAP SYSTEM™ (ESS)
ESS combines Giant’s light, micro-adjustable Cinch Pro™ fit system with Optimal Position Dividers and LiteForm™ webbing, resulting in a single-purpose fit and retention system with a secure, comfortable fit right out of the box.
TRANSTEXTURA PLUS™ ANTIMICROBIAL PADDING
These highly advanced natural fabrics fight bacteria growth by pulling sweat from a rider’s head and transferring it through the AeroVent exhaust ports. The natural property of the fabric inhibits microbes that cause odors.
