Bell 4Forty MTB Helmet - 2021

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 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.


  • 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 overmolded dial for adjustments
  • 15 vents
  • 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
  • Weight: 324 grams (size M)
Mr CarmanBrilliant service as usual from Merlin, helmet is a superb fit, having a large noggin has always been a problem when trying to buy helmets. Price was extremely good and service to match, thank you Merlin.
StMdVery nice helmet, Sizing is ok, fits very well and the sweat guide seems to work, flows to the center. The visor is also good and stable. The foam inside is enough plenty so is comfortable too.
Mr SharinPerfect fit. Light and good sweat absorber. Could be better with MIPS included.
Mr MichaelNice helmet very comfy and a good fit
