Product Details

Bell 4FORTY Mips Helmet

All-mountain value, Float Fit, Sweat Guide, adjustable visor, full hard shell—the 4Forty is ready for anything the trail throws your way. The only thing missing is a triple digit price tag.

Off-Road Overacheiver

Mountain biking is a demanding sport—compromises and shortcuts when it comes to gear are never a good idea. The 4Forty is built to withstand the rigors of a trail riding life; with generous ventilation, the comfort of Float Fit and built-in Sweat Guide, extended rear coverage, a full hard-shell, adjustable visor, and the option of integrated MIPS protection. Boasting the comfort, protection and broadly capable features of helmets costing twice as much, the 4Forty is a bantamweight, all-conditions, all-kinds of trail champion packing a heavyweight value.

What is Mips?

  • Mips means Multi-directional Impact Protection System.
  • Mips was developed by a team of Swedish brain surgeons and neurologists who tasked themselves with creating a better bicycle helmet dedicated to reducing the rotational acceleration forces to the brain in the event of an angled impact.
  • Mips is a super-flexible low friction nylon head-hugging liner, designed to rotate inside the helmet in the event of an impact from any angle.
  • Mips thus helps reduce the resulting rotational energy being transfered to the head - rotational energy that could otherwise cause serious injury to the brain should it violently impact the inside of the skull in the event of a crash.
  • Mips therefore goes a long way to addressing the most frequent criticism of first generation helmets - that they are primarily designed to absorb the energy of a vertical head-on impact, and are less effective at saving you in the event of the type of angled impact, which is more likely to occur.
