Protective helmet BELL Super Air Mips Spherical, size M (55–59 cm), matte/gloss gray

The BELL Super Air Mips Spherical in size M (55–59 cm) is a full-face mountain bike protective helmet designed for trail and enduro riding. It combines a removable multi-impact chin bar, Mips rotational impact protection and Spherical technology to manage linear and rotational forces during a crash. The helmet offers extended rear and side coverage compared with standard trail helmets and integrates ventilation channels to balance airflow and protection for off-road conditions.

Advantages

The helmet’s Spherical technology pairs with Mips to reduce rotational acceleration transmitted to the head, while the multi-impact chin bar is engineered for repeated impacts typical in aggressive trail and enduro use. The removable chin bar enables transformation between full-face and open-face configurations without compromising fit, and the extended coverage improves protection around the temples and occipital area. Ventilation ports and internal routing provide cooling during long climbs and aggressive descents while maintaining structural integrity.

Suitable for

• Trail riding and enduro stages requiring both impact protection and ventilation
• Riders who want the option to switch between full-face and open-face setups
• Technical descents and jumps where extended coverage is preferred
• All-day rides that demand comfort, airflow and secure fit

Key specifications

• Fit size: Medium (55–59 cm head circumference)
• Construction: Integrated full-face shell with removable multi-impact chin bar
• Impact systems: Mips rotational protection combined with Spherical energy management
• Coverage: Extended rear and side shell contours for additional protection
• Ventilation: Multiple intake and exhaust ports with internal airflow channels
• Weight: Manufacturer-optimized for trail durability and comfort (exact weight varies by configuration)
• Padding: Removable and washable comfort liners designed for sweat management
• Retention: Adjustable retention system for secure fit and micro-adjustability

How to use

Choose the correct size by measuring head circumference and position the helmet level on the head so the front edge sits just above the eyebrows. Attach or remove the chin bar according to the desired configuration following the manufacturer’s assembly instructions, ensuring all fasteners lock into place. Fasten the chin strap securely and adjust the retention system so the helmet fits snugly without excessive movement. Inspect the helmet before each ride for cracks, damaged padding or worn straps and replace parts as needed.

Usage recommendations

Use the helmet in its full-face configuration for technical descents, jumps and high-risk sections; switch to the open-face setup for climbs and less technical trail sections to improve ventilation. Replace the helmet after significant impact or whenever structural damage is visible. Clean removable liners regularly and follow manufacturer guidance for storage to maintain protective performance.
