Mountain biking is a demanding sport -- compromises and shortcuts when it comes to gear are never a good idea. The Bell 4Forty MTB helmet 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 and adjustable visor. 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.
Key Features:
- Fusion In-Mold polycarbonate shell - A process pioneered by Bell bonds the helmet's outer shell to the EPS foam liner to create a sturdier helmet.
- Float Fit - A minimalist, lightweight fit system with an easy-to-turn rubber overmoulded dial for adjustments
- 15 vents for a cool head on the climbs
- GoggleGuide adjustable visor: accommodates both goggles and glasses
- No-Twist Tri-Glides: Quick-adjust fasteners that help keep straps flat and properly positioned
- Sweat Guide pad design pulls moisture away from the brow pad and away from eyewear
- CE EN1078 certified

How to measure
To find the circumference of your head, place a tape measure in the centre of your forehead, wrap it around above your ears and around the back of your head. If there's a slight difference between two different sizes, always go for the tighter size.
Once you know the circumference of your head, select a size with a range that your head size fits within.

As well as an adjustable chin strap the majority of cycling helmets have some form of adjustment for size, usually in the form of a ratchet adjuster to tighten or loosen the headband or replaceable pads of different thicknesses.
