Troubleshooting

Straps frequently twist despite Tri-Glides
Re-thread the straps through the glides, ensuring they are fully untangled, and snap the glides into the locked position.

Setup, Compatibility & Care
To set up your Bell 4Forty, start by loosening the rear Float Fit dial before placing it on your head. Once positioned, tighten the dial until the helmet is snug but comfortable. Adjust the No-Twist Tri-Glides to lie flat against your cheeks, ensuring the Y-junction sits just below your ears. For care, gently clean the outer shell with mild soap and water using a soft cloth; avoid harsh chemicals that can degrade the polycarbonate shell. The internal pads are generally moisture-wicking and should be hand-washed periodically. Always store the helmet in a cool, dry place away from direct sunlight when not in use.
