<!--ProdInc[300301166]/Mall:[backcountry_US]-->The lightweight Specialized Propero 4 Bike Helmet brings comfort, confidence, and high speeds to our ride with its durable full-wrap polycarbonate shell, optimized ventilation, and aerodynamic technologies. Using the DNA of the S-Works Prevail 3 and S-Works Evade 3 helmets, Specialized designed a helmet that balances speed and ventilation by utilizing Computational Fluid Dynamics (CFD) for an increase in airflow and cooling with the leading-edge aerodynamic efficiency of the front-end design. To increase protection, we adjust the FS3 Fit System and Occipital Base Adjustment for a personalized fit for our head shape, keeping the helmet secure and in place, while the use of Mips technology reduces rotational force to the head upon unwanted impacts. <h3>Details</h3> Helmet with optimized aerodynamics, ventilation, and lightweight design Precision, full-wrap polycarbonate shell for added durability Tested to be 4 watts faster than the S-Works Prevail 3 in the wind tunnel Micro Channeling creates turbulence in the airflow for continuous circulation Mips C-Solution helps reduce rotational force to the head upon impact Find a perfect, secure fit with the FS3 Fit System and Occipital Base Adjustment Stash glasses in the built-in storage during coffee stops or bathroom breaks Item #SCQ1X05 <h3>Tech Specs</h3> Shell Material : polycarbonate Impact Management : Mips C-Solution Ventilation : micro channeling, large rear-end vents Fit Adjustment : FS3 Fit System and Occipital Base Adjustment Certifications : Complies with U.S. CPSC Safety Standard for Bicycle Helmets for Persons Age 5 and Older.
