Super Air R Spherical

Designed for trail and enduro riders who want descent protection without the stifling heat of a standard full-face lid, this convertible helmet solves the two-helmet dilemma. A tool-free, two-latch removable chin bar switches the chassis from an airy half-shell for grinding up fire roads into full-face coverage before dropping into rocky singletrack. It caters directly to backcountry epics and hot all-mountain climbs where lugging a dedicated downhill helmet is impractical.

Inside, Bell uses Spherical Technology powered by Mips, which acts like a ball-and-socket joint between two separate foam liners—one high-density EPS, the other lower-density EPP. This setup absorbs varied impact velocities while eliminating the interior plastic slip-plane that often catches hair or compromises airflow. On the trail, the ventilation is standout: the deep brow intake ports channel air across the crown effectively enough that you can leave the chin bar mounted during rolling terrain without overheating.

The critical compromise is protection level. This helmet is intentionally optimized for lightweight trail and light enduro duties, meaning it does not carry the heavier ASTM downhill safety certification found on dedicated park helmets or its burlier sibling, the Super DH. If your weekends involve steep shuttle laps or bike park jumps, you will want more mass in front of your face. But for aggressive pedaling where breathability and low weight reign supreme, it strikes an exceptional balance.
