Item # BEL00CU

Next level.

Wearing a helmet worthy of a recreational roadie doesn't have to mean dropping pro-level prices. Bell's Overdrive MIPS Helmet weighs just grams more than its pricier siblings and costs a fraction of the price. If getting outside for long Sunday rides and commuting to work are more important to you than heart rate zones and training plans, grab the Overdrive MIPS when your helmet needs replacing.

Bell trusts an In-Mold polycarbonate/EPS shell and MIPS liner to provide reliable impact resistance, and we trust that particular combination, too, especially when combined with MIPS. MIPS, or Multi-Directional Impact Protection System, refers to the Swedish technology added to the helmet in the form of a thin, inner basket. This basket moves independently of the In-Mold shell, so it rotates slightly upon impact to absorb and diffuse rotational energy generated by certain impacts.

During the majority of your rides, when you hopefully have no need for the helmet's safety features, you'll enjoy an airy array of 19 vents plus easy fit adjustment with Bell's FloatFit technology. Bell treats the straps to make them less likely to absorb sweat—so you can ride for longer before resembling a salt lick or feeling compelled to keep your helmet on for the post-ride shower—and uses a compact, aerodynamic shape inspired by its higher-end models to reduce drag in the wind.

  • Ride in a road-specific helmet without draining your wallet
  • Sleek design inspired by Bell's pricier models
  • MIPS technology diffuses rotational force in certain crashes
  • In-mold shell absorbs energy from direct impacts
  • Wealth of vents keep air moving continuously
  • FloatFit technology makes fit adjustments quick and easy
