Meet the all-new Propero 4 helmet—it brings the aero advantages of the S-Works Evade 3 together with the ventilation of S-Works Prevail 3, all with the comfort and confidence Specialized helmets are famous for, earning the highest 5-Star Virginia Tech® helmet rating. Every detail of the Propero 4 was created with our equation for speed in mind. Aerodynamics + Ventilation + Lightweight = Fast.

AERODYNAMICS: With extensive testing in CFD and in our Win Tunnel, aerodynamics were at the forefront of the Propero 4 development. We took the aerodynamic leading edge from the S-Works Evade 3 and pulled it directly into the Propero 4—which helped it to be four watts, or 15 seconds over 40km, faster than our S-Works Prevail 3.

VENTILATION: Drawing inspiration from our world-renowned S-Works Prevail 3, our goal was not merely to replicate but to elevate. Ventilation became a focal point in our quest for a well-balanced, aerodynamic, and ventilated helmet. We incorporated the rear-end design language of the S-Works Prevail 3 and introduced small 2mm offset micro-channels that create turbulence in the airflow throughout the helmet to help create a continuous, refreshing flow of air.

ATTENTION TO DETAIL: Beyond just aerodynamics and ventilation, the Propero 4 represents meticulous attention to detail. We went the extra mile by incorporating cutting-edge technologies from our S-Works level helmets, like MIPS technology for confidence, and a fit system designed to deliver all-day comfort. The Propero 4 doesn't just meet expectations

  • Mips Evolve Solution is a low-friction layer that allows a sliding motion of 10 to 15mm in all directions. Studies indicate that this reduces some of the rotational forces transmitted to the brain during angled impacts.

  • Propero 4 earned the highest 5-Star Virginia Tech® Helmet Rating from internationally renowned Virginia Polytechnic Institute and State University.

  • FS3 Fit System & Occipital Base Adjustment optimizes comfort by personalizing fit to individual head shape, and helmet angle can be adjusted for compatibility with glasses.

  • Adjustable Tri-Fix web splitter combined with thin 10mm webbing for increased comfort.

  • Dedicated sunglass storage maintains a secure fit and keeps eyewear out of the way when needed.

  • Micro Channeling & large rear-end vents for increased ventilation.

  • S-Works Evade 3 front-end design language for enhanced Aerodynamics.

  • Precision, full-wrap polycarbonate shell for increased durability and premium finish.

Lightweight and nice design

Very pleased with my new helmet. It has a nice design and is lightweight. It was quite a different shape to my previous one which took a little getting used to as it doesn't seem to come as close to the tops of my ears, but now I'm used to it it's very comfy. Great service from Specialized helping me out with it. Thanks

Padding falls apart after 6 months use

After six months of moderate use - used on average 3 times per week at most - the backing of the padding has completely pulled away from the pad itself. So, there is now no way to reattach the padding and it makes the helmet useless. I have helmets 10 years old where the padding is still intact and six months is nothing. Surely this is faulty design or production? Hoping Specialized will replace either the padding or the helmet.

Excellent helmet

As description the ventilation is excellent can feel the air flow from the front to the top and exit through the rear my hairs is flying. but didn’t tried prevail 3 do believe it will be better ventilation. The aero is good for all position. My old helmet getting better aero only when you faced down. But this helmet done it with all position. Helmet is fit and very comfy.
