Bell Bike

Frequently Asked Questions

• How does the Full-10 Spherical compare to the Nomad for downhill versus enduro riding?

  The Full-10 Spherical is a full-face, downhill-focused helmet with Spherical MIPS, multi-density EPS/EPP liners, and extensive coverage plus five cheek-pad thicknesses for a race-ready fit, making it better suited to high-speed, high-energy impacts. The Nomad is an open-face enduro/trail helmet that balances Spherical MIPS protection with lighter weight, more ventilation and a multi-position visor, so it’s a better pick for long climbs and mixed trail days.
• How should I size a Bell mountain bike helmet and which fit system is best for my head shape?

  Measure your head circumference and use the model-specific size chart—many Bell helmets span common head shapes in two sizes, while models like the Full-10 offer XS–2XL and multiple cheek-pad thicknesses for finer tuning. Try the helmet with your goggles and hair in place and choose the fit system that matches your preference: Float Fit or Ergo Fit for micro-adjustability, FIDLOCK for one-handed convenience, and Magna Fusion cheek pads if you want removable, washable comfort.
• What safety technologies do Bell helmets use to manage rotational and linear impacts?

  Bell integrates MIPS and MIPS Spherical (ball-and-socket EPS/EPP layers) to mitigate rotational forces, combined with progressive-density EPS/EPP liners and In‑Mold shells to control linear-energy absorption. Select helmets also meet activity-specific standards (CPSC, CE, ASTM DH, NTA e‑bike) and include crash-conscious features like breakaway mounts and secure retention hardware.
• Which Bell helmet features should enduro and technical trail riders prioritize?

  Enduro and technical riders should prioritize Spherical MIPS, extended rear coverage, multi-density EPS/EPP liners and a low-profile shell for improved impact management, along with a multi-position visor and robust ventilation for long efforts. Also look for secure goggle integration, adjustable fit systems (Float Fit or Ergo Fit), and antimicrobial pads such as X‑Static or Ionic+ to maintain comfort on multi-day outings.
