Giant Rivet Helmet
On the road bike, boosting your aerodynamics is the easiest way to increase your speed. Over the past few years, cycling helmet manufacturers have worked to make lids more aerodynamic, but better aerodynamic qualities have often come at the expense of weight and ventilation. Vents, in particular, tend to disrupt airflow.
Engineers at Giant believe they have cracked the code with the new Rivet road helmet. The Rivet was designed with fluid dynamics modeling and tested in the wind tunnel. But Giant also wanted to make a well-ventilated lid. The Rivet boasts three large vents that feed air into deep channels that run through the inside of the helmet, while four more vents provide outflow at the back. Giant claims the venting this system makes for a uniquely comfortable, aerodynamic helmet.
Giant has also sought to simplify the process of adjusting helmet straps. Though the system may not work for all heads, we found it refreshingly easy to adjust the Giant Rivet to fit. The Rivet may not make you as fast as Giant-Alpecin's John Degenkolb who recently won the famed Paris-Roubaix road race, but it just might help you beat your Strava rivals. [$160; giant-bicycles.com]
