BELL Super Air R MIPS Adult Mountain Bike Helmet - Matte/Gloss Grays (2021), Medium (55-59 cm)
Brand: BELL
Color: Matte/Gloss Grays (2021)

As pioneers of removable chin bar technology, we have a legacy to uphold and overcome. We designed the Super Air R from the ground up to push the boundaries of performance and versatility—starting with Spherical Technology. Spherical Technology's Ball-and-Socket design, powered by MIPS, helps redirect impact forces away from the brain by allowing the outer liner to rotate around the inner liner during a crash. Throw in superior ventilation, a total weight that is 22%, or 144 grams, lighter than its predecessor, and an easy 2-click removable chin bar—and you've got a true all-mountain performer.

FUSION IN-MOLDING POLYCARBONATE SHELL AND PROGRESSIVE LAYERING - A process pioneered by Bell bonds the helmet's outer shell to the EPS foam liner to create a sturdier helmet. The process of engineering a helmet liner with variable EPS foam densities to better manage the transfer of energies after some impacts.
FLEX SPHERICAL + MIPS - Comprehensive energy management. Flex spherical enhances our ability to address high-speed impacts, low-speed impacts, as well as rotational impacts. Think of it as comprehensive protection, with the added bonus of being able to design better helmet ventilation.
X-STATIC PADDING AND WRAPAROUND CHIN BAR - Quick-drying materials, woven with real silver fibers. A removable protective chin bar, designed for trail riding adaptability -- no tools required. Warning: all chin bars have limits, and serious injury or death can occur. Read the owner's manual carefully before using your helmet.
OVERBROW VENTILATION, GOGGLEGUIDE ADJUSTABLE VISOR SYSTEM, AND INTEGRATED BREAKAWAY CAMERA MOUNT - Overbrow Ventilation features intake ports on the brow of the helmet to usher in cool air and push it through the air-channel matrix for full-head ventilation. Adaptable visor system accommodates both goggles and glasses and works with or without the visor attached. Seamless camera mount, requiring no zip ties or tape, is engineered to break away upon impact to reduce the risk of injury.
SPECIFICATIONS - Small (52-56 cm), Medium (55-59 cm), and Large (58-62 cm) Sizes. Important: always take a head measurement. Head sizes and shapes can vary, even within an age range. Using a helmet that does not fit can be dangerous; 18 Vents, 4 Brow ports, and 8 Chin Bar vents.
