Bell Super 2 Mountain Bicycle Helmet Closeout. If all out enduro or all mountain trail riding is how you roll outdoors, then the Bell Super 2 mountain Bicycle Helmet is tailor made for you. It provides full, extended protection with lower rear coverage than most of the competition, plus uncompromising comfort and ventilation to help you charge up the climbs. The Super 2 is loaded with technologies including cooling Overbrow Ventilation, a breakaway camera mount, and an upgraded Twin Axis Gear TAG fit system that makes dialing in fit easier than ever. And best yet, it is compatible with the Super 2R chin bar for easy conversion into a full face Bicycle Helmet.
