Upgrade to the new, cooler you.
Discover Oracle. Massively ventilated, carbon fiber-reinforced protection for your head.
Low profile. Massively ventilated. Exceptionally aerodynamic. Oracle is a pro-caliber road helmet for riders who won't settle for anything but the best. Featuring an in-molded carbon fiber skeleton that provides the superior structural integrity and load dispersal necessary to create the biggest possible vents in the lowest-profile design, Oracle uses internal channeling and CFD-optimized ventilation to maximize airflow efficiency through the helmet and over the head, for impressive levels of cooling and drag reduction.
