The frontal area of the helmet, critical to aero performance, features a radius-shaped curvature designed through Computational Fluid Dynamics analysis. The unique shape reduces drag across all angles for higher speed in TT or triathlon efforts.

The Attacca-TT Helmet
Bereik de toppen van jouw kunnen tijdens tijdritten met de Attacca TT helm. Van voor naar achter, elke vorm van de nieuwe Attacca TT is ontwikkeld voor optimale aerodynamica. Tests in windtunnels bevestigen het aantoonbare voordeel in verschillende houdingen, tijdens verschillende windrichtingen, perfect voor triatlons en tijdritten.
Highlights
De Attacca TT combineert aerodynamische prestaties met optimale fit en comfort. Dit vormt een onverslaanbare combinatie voor triatlons en tijdritten. De voorkant is radiusvormig en ontwikkeld door Computational Fluid Dynamics om weerstand te minimaliseren. De bovenkant van de helm is zo vormgegeven dat de lucht zo efficiënt mogelijk naar de achterkant van de helm stroomt. De staart is ingekort, een design dat bewezen heeft effectiever te zijn in verschillende houdingen en windrichtingen. Door de vier Aerovent ports wordt de temperatuur gereguleerd om comfort te kunnen leveren.

DIMPLED DESIGN
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.

SHORTENED TAIL
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.

AEROVENT PORTS
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.

AEROVENT CHANNELS
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.
