Mountain Cross Country Bicycle Helmet with In-Mold Polycarbonate Shell and Removable Chin Bar

This mountain cross country bicycle full helmet is designed for extreme sports safety, offering reliable protection for cycling, skateboarding, and roller skating. Weighing just 550 grams, it keeps weight low without compromising coverage. The one-size M/L (56-62cm) fit accommodates a wide range of riders, with a super fit design that works for both Asian and Western head shapes. The adjustable LFS Light Fit System and removable chin bar make it versatile for trail riding or everyday use, while 19 Wind Tunnel vents actively cool the head during intense activity.

Features and Construction

Built for durability and comfort, this helmet combines an in-mold polycarbonate shell with an EPS liner and thermoformed reinforcement polystyrene. The multi-density impact reduction system provides enhanced protection against shocks. The adjustable visor system works with goggles or glasses and can be used with or without the visor attached.

Material and Build

The outer shell is constructed using in-mold polycarbonate, fusing the shell and EPS liner for a strong, lightweight structure. Inside, thermoformed reinforcement polystyrene adds further shock absorption. Breakaway AI Alloy Screws allow the visor to detach on impact, reducing rotational forces.

Size and Practical Fit

Available in one size M/L (56-62cm), the helmet fits most adult riders. The LFS (Light Fit System) uses an easy-to-turn rubber overmolded dial for precise adjustments, ensuring a snug and comfortable fit. The super fit design is tailored for both Asian and Western head shapes, enhancing comfort during long rides.

Uses and Placement

This all-mountain helmet is designed for cross-country cycling, trail riding, and other extreme sports requiring head protection. Its extended back coverage and removable chin bar make it suitable for different riding conditions. The 19 Wind Tunnel vents and internal channeling regulate temperature effectively during high-exertion activities.

Event or Professional Use

Compliant with CE EN 1078, CPSC 1203, and AS/NZS 2063 safety standards, this helmet is approved for cycling, skateboarding, and roller skating for persons aged 5 and older. The removable chin bar allows quick conversion from full-face to open-face for varied trail conditions.

Everyday Home Use

For casual riders and commuters, the lightweight 550 gram design reduces neck fatigue. The Clean Tex antibacterial pads help maintain hygienic freshness with regular use, while the adjustable visor keeps sun and debris out of the eyes.
