﻿Rivet TT Helmet | Giant Bicycles Portugal

Unbeatable performance for TT or triathlon. Front to back, every curve and shape of the new Rivet TT is fine-tuned through Computational Fluid Dynamics for optimal aerodynamics.  And on the road, it delivers unrivaled fit and comfort to real-world athletes like triathlete Tim Berkel, who helped refine its design. 



The first priority of the Rivet TT is aerodynamics. Second is fit and comfort. Put them together and you have unbeatable performance for TT and triathlon. It starts with the shape. The frontal surface is radius shaped and engineered using CFD to minimize drag. The top area features two strategic dimples to stream airflow toward the rear. The tail is shortened, a design that’s proven effective in a variety of rider positions and wind directions. The AeroVent cooling system, made with four “drag-neutral” ports and internal channels, helps regulate temperature for critical comfort during hard efforts.
