FAQs
Is this helmet suitable for mountain biking?
While it can be worn, the Isode II is designed specifically for road cycling; it lacks the extended rear coverage and visor found on dedicated mountain bike helmets.
How do I adjust the fit?
Use the dial at the back of the helmet to expand or tighten the fit range by up to 7cm.
Does it come in different sizes?
The Isode II utilizes a versatile fit system designed for a wide range of adult head sizes.
Can I replace the internal pads?
Yes, the internal padding is designed to be removable for washing or replacement to keep your helmet fresh.
How often should I replace the helmet?
It is recommended to replace any helmet if it has been involved in an impact, or every 3-5 years due to natural material degradation.
Troubleshooting
Helmet feels unstable or rocks on the head
Ensure the Roc Loc Sport dial is tightened sufficiently and check that the rear fit system is positioned at the base of your skull.
Straps are twisting or uncomfortable
Adjust the Y-junction sliders located under the ears so the straps lie flat against the sides of your face.
Dial adjustment is stiff
Ensure no debris or grit has entered the dial mechanism; clean with a gentle stream of water if necessary.
Pros and Cons
Pros
- Excellent ventilation through 16 large vents
- Easy one-handed fit adjustment
- Lightweight in-mold construction
- Professional styling at an accessible price point
Cons
- Lacks specific features for mountain biking
- Limited to road-specific use cases
- Minimalist aesthetic may not suit all personal styles
Setup, Compatibility & Care
To ensure a proper fit, first loosen the Roc Loc Sport dial completely. Place the helmet level on your head so it covers your forehead. Tighten the rear dial until the helmet is snug but comfortable; you should be able to shake your head side-to-side without the helmet shifting. Regularly check that the chin straps sit flat against your skin and the Y-junction sits just below your earlobes. Clean your helmet using only mild soap and a damp cloth; avoid harsh solvents or high-heat storage, as these can degrade the polycarbonate shell or the internal foam liner over time.
