The Sixer MIPS 4Forty Spark Nomad helmets from Bell offer a range of features for various cycling disciplines. These include a fusion in-mold polycarbonate shell, which is a process pioneered by Bell that bonds the helmet's outer shell to the EPS foam liner, creating a sturdier helmet.

The helmets are also MIPS-equipped, meaning they feature the Multi-directional Impact Protection System - a leading slip-plane technology designed to reduce rotational forces that can result from certain impacts. The fit systems vary across the models, with the Sixer and 4Forty featuring a minimalist, lightweight Float Fit system with an easy-to-turn rubber overmolded dial for adjustments (integrated with MIPS), while the Spark and Nomad have an Ergo Fit - a sleek, easy-to-use dial system for one-handed adjustments (also integrated with the MIPS layer).

Ventilation is addressed through features like the Dual Flow Ventilation on the Sixer, which includes air ports along the brow to provide ventilation and help defog goggles. The 4Forty, Spark, and Nomad models have 15, 13, and 15 vents respectively.

The visors are also adjustable, with the Sixer offering a 4-position no-slip design, the 4Forty having a Goggleguide adjustable visor system to accommodate both goggles and glasses, the Spark featuring an integrated visor, and the Nomad having a removable visor.

Additional features across the range include sweat guide pad designs that pull moisture away from the brow pad and eyewear, and no-twist tri-glides that help keep straps flat and properly positioned.

In terms of size options, the Sixer and 4Forty are available in S, M, and L, while the Spark and Nomad come in UXL and UA. The weights vary, with the Sixer being 410g (size M), the 4Forty 380g (size M), the Spark 365g (size UA), and the Nomad 333g (size UA).

With their combination of protective technologies, ventilation, and user-friendly adjustability features, these Bell helmets cater to the needs of mountain bikers, road and gravel riders, BMX enthusiasts, and younger cyclists alike.
