The Smith Jetstream TT Mips Road Bike Helmet is for riders looking to focus on aerodynamics and make sure every second of speed goes unaccounted for. This helmet is specialized for time-trials and riders looking for durable, lightweight comfort and performance. The fusion of Zonal KOROYD and MIPS creates the best source of coverage and protection from impacts caused by great momentum. It features VaporFit dial that provides 270-degree fitting as well as a low-profile Y-strap divider that'll reduce wind noise and aerodynamic drag.
