FAQs
Is this helmet MIPS-equipped?
The standard Bell 4Forty features the specified hard-shell design and fit systems, but please check your specific product packaging or retailer label for MIPS-specific model variants.
Can I wear glasses with this helmet?
Yes, the Goggleguide visor system is designed to accommodate both large MTB goggles and standard cycling sunglasses.
How do I adjust the visor?
The visor is adjustable vertically; simply tilt it to your preferred position to clear your eyewear or increase field of view.
Is the padding removable?
Yes, the internal padding is removable and can be hand-washed with mild soap and water to keep the helmet fresh.
What is the best way to store the helmet?
Store your helmet in a cool, dry place out of direct sunlight. Avoid leaving it in a hot car, as extreme heat can damage the helmet structure.
Troubleshooting
Helmet feels loose even when dial is tightened
Adjust the rear height setting of the Float Fit system cradle to better match your skull shape.
Straps continue to twist during rides
Ensure the No-Twist Tri-Glides are locked securely after you have finished adjusting the strap length for your face.
Sweat dripping into eyes
Ensure the brow pad is properly seated in the Sweat Guide channel and check if the padding needs washing to remove salt buildup.
Pros and Cons
Pros

- Not optimized for road cycling aerodynamics
- May feel heavy compared to dedicated racing helmets

Setup, Compatibility & Care
To ensure a safe fit, start by loosening the rear dial of the Float Fit system before placing the helmet on your head. Once positioned, tighten the dial until snug, then adjust the side straps using the No-Twist Tri-Glides until they sit flat against your face and under your ears. The visor can be adjusted vertically by loosening the side hardware, allowing for compatibility with various goggle brands. To clean the helmet, use only mild soap and water with a soft cloth; avoid using chemical solvents or strong detergents that could compromise the integrity of the shell or foam liner.
