Bell Super Air Spherical Helmet

The Bell Super Air Spherical Helmet is Bell's convertible trail helmet, built around Flex Spherical protection technology paired with MIPS. Instead of a single rigid shell, it uses a two-piece inner and outer construction connected by tensioned elastomers, letting the outer layer shift independently during an impact to help manage low-speed, high-speed, and rotational forces in one system. The shell itself is Fusion In-Mold polycarbonate, bonded directly to a Progressive Layering EPS liner that varies foam density across the helmet to tune impact absorption where it matters most. It's the same platform Bell builds its full-face Super Air R around, just without the chin bar included.

Ventilation runs deep for a helmet built with this much protection: 18 vents and 4 brow ports channel air through an Overbrow intake system, with wide exhaust ports at the rear pulling heat out on sustained climbs. The Float Fit system dials in a secure hold with a minimalist rubber adjustment wheel integrated with the MIPS liner rather than bolted on separately, and a sweat guide pad routes moisture away from your eyes and eyewear before it becomes a distraction. The mid-length visor adjusts across multiple positions, with enough clearance to run it up over goggles on rougher descents.

What sets the Super Air Spherical apart from a standard trail helmet is its compatibility with Bell's optional chin bar, sold separately, which converts it toward full-face-style coverage for bike park laps or steeper descending days. It's worth noting the helmet isn't downhill certified even with the chin bar attached, so it's built for trail and enduro riding rather than DH racing. RA Cycles carries the Super Air Spherical in Fasthouse Matte Black / White, sized Small through Large. For riders who want one helmet that adapts between all-day trail rides and rowdier descents, the Super Air Spherical covers both ends without needing two separate lids.
