The S-Works Prevail 3 helmet is perfect for riders who value the comfort and thermoregulation benefits that superior ventilation delivers. It is the ultimate all-around helmet that excels in hot conditions, strenuous climbs, and mountainous stages.
With a never-ending quest to push the limits of ventilation, we eliminated air-blocking foam “bridges” from the center, effectively creating thru-air channels that increase the surface area of ventilation by 24.5% compared to the S-Works Prevail II Vent helmet. The all-new S-Works Prevail 3 has the most ventilation area of any helmet we have ever made.
When a helmet is impacted, its job is to dissipate the energy of the impact. The conventional approach to helmet design is that more foam (EPS) means better energy management. We re-wrote the book on cycling helmet design by innovating beyond foam. Woven aramid “cables” traverse the helmet and are anchored to carbon fiber side panels. Upon impact, the AirCage technology* works as a suspension bridge and is designed to distribute localized forces throughout the helmet.
The Occipital Base Adjustment optimizes comfort by personalizing fit to individual head shape and helmet angle can be adjusted for compatibility with glasses. An adjustable Tri-Fix web system gives riders added comfort with updated, thinner 10mm webbing that minimizes strap noise. And the ultralight Mindset micro-dial fit system with height adjustability has been updated for improved grip and reaction for easy on-the-go fit.
Our ultralight and supremely comfortable MIPS Node Air technology is integrated directly into the helmet padding, with a sleek low friction layer designed to dissipate rotational forces. With Specialized’s proprietary development work, we added perforations to maximize breathability, performance, comfort, and weight savings.
For helmets sold in the U.S. and Canada: Complies with U.S. CPSC Safety Standard for Bicycle Helmets for Persons Age 5 and Older.
The S-Works Prevail 3 is one of the most comfortable bike helmets I’ve worn. The fit system adjusts perfectly, and once I ratchet the MIPS cradle to my head, the helmet almost disappears — it conforms so well that I barely notice I’m wearing it.
Ventilation is excellent. Riding in moderate weather around the mid-70s, my head stayed cool and comfortable without overheating. The airflow design really works.
Thankfully, I haven’t had to test the helmet in a crash, and I hope I never do. But the build quality and design give me a lot of confidence in the protection it offers. Highly recommended.

Very impressed by the whole experience with Sierra Bicycle Supply! The frameset was just as shown - brand new and gorgeous. It shipped fast with tracking info. Great pricing on the frameset and I picked up other stuff for my build. Great overall experience - highly recommended!!
Amazing bike at super price. Free shipping. Highly recommend buying from these guys.
Here is how I am using it.
- Customizable displays for ...
- Heart Rate Sensor
- Garmin Pedal Power Meters
- Lights control
- Cadence Sensor
- Speed Sensor
- DOES NOT WORK WITH SAMSUNG WATCH 8 CLASSIC
- Records Route Creation but need to be careful with saving rides as not doing two rides back to back = lost
- does not come with a one hundred twenty page manual.But I was able to find a pdf file online
I have had gatorskin tires for several years. They are by far the best tire.
Nice and light but plenty stiff. Great for all around riding on my Epic Evo.
