Helmets

With more all-around coverage, the Sidetrack II is suited for the adventurous grom in your life. This all-mountain helmet offers a removable visor, an easy adjustable fit system, our sweat guide padding, and ready-for-action style that will get your child motivated to hit the trail!
- 14 vents
- Integrated MIPS (Multi-directional Impact Protection System) - MIPS is designed to reduce rotational forces that can result from certain impacts. By integrating the MIPS slip plane into the fit system, we are able to reduce complexity and weight for a compact, better ventilated helmet that fits more closely to the head.
- Construction: Fusion in-mold polycarbonate shell - a process pioneered by Bell bonds the helmet's outer shell to the EPS foam liner to create a sturdier helmet.
- Fit System: Ergo fit - sleek, easy-to-use dial system for one-handed adjustments (integrated with MIPS layer)
- Retention System: No-twist tri-glides: quick-adjust fasteners that help keep straps flat and properly positioned
- Interior: Sweat guide pad design pulls moisture away from the brow pad and away from eyewear

When we set out to improve the original S-Works Prevail, we knew that we had our work cut out for us. How could we improve on the industry benchmark for fit, ventilation, and comfort? By listening to our riders—that’s how. Through this, we realized that there were a few aspects of the original Prevail II that needed to be changed, with the biggest request being for a lower-sitting design.
We thought to ourselves, "thinking big shouldn't result in bigger helmets," so with the Prevail, we set out to prove that big ideas can come in smaller packages. It all starts with our patented EPS construction that relies on multi-density foam that's paired with a robotically woven, Aramid-reinforced skeleton. This comes with a reduction in the overall size, creating a smaller profile that fits lower down on the head for a better fit and safety.
It also has deep internal channels that are aligned from front-to-rear, so the air intake and exhaust are optimized for unparalleled cooling over the entire head. And in the Win Tunnel, we found these new designs amounted to six seconds saved over 40km when compared to a "standard" road helmet. Another standout feature of the S-Works Prevail II is the Gutter Action System that manages the flow of sweat, keeping it away from your eyes and dripping it off of the pads over your temple.
Our new ANGi Crash Sensor gives you and your loved ones peace of mind like never before—when combined with our iOS or Android app, the sensor will detect a crash and send a text message to specified contacts in your phone. It also syncs with our app and STRAVA to provide GPS-based activity tracking.
In the end, the S-Works Prevail II is the most complete lightweight race helmet we've ever made—perfect for hot, mountainous rides and flat, windy sections alike.
