Why We Like The Specialized Propero 4 Bike Helmet
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.

nicely finished, but didn't look right
- Familiarity:
- I returned this product before using it
- Size Bought:
- M
The helmet is clearly high quality, but sits high on the head, resulting in the dreaded "mushroom" look. Had to return and didn't ride with it to assess performance.
