Fizik Kudo Aero Helmet Shaped for speed, built for safety The Fizik Kudo Aero is a performance-focused half-shell helmet built for fast road, gravel, and XC MTB riding. Its aerodynamic shell features an optimized rear spoiler and EPS extension designed to cut drag without sacrificing coverage, while two front intake vents and a wide rear exhaust outlet keep airflow moving during hard efforts. The rounded shell shape is crafted to reduce surface grip on impact, and a crossbridge element embedded in the EPS foam distributes impact forces across the helmet for full-coverage protection. MIPS Air Node technology adds ultralight rotational impact protection, and the micrometric occipital fit dial with tilt and crown adjustment dials in a precise, personalized fit. A USB-rechargeable LED taillight and removable rear reflector round out the package. At 290g, the Kudo Aero doesn't make you choose between speed and safety.
