Setup, Compatibility & Care
To achieve the best fit, place the helmet level on your head and tighten the BOA dial until the internal cradle snuggly grips the back of your skull without feeling restrictive. Ensure the straps lie flat against your cheeks and the buckle sits comfortably under your chin. For care, use a soft, damp cloth and mild soap to clean the exterior shell and internal pads. Avoid using harsh chemicals or solvents, as these can degrade the integrity of the EPS foam. If you are involved in a significant impact, remember that the helmet comes with a crash replacement guarantee, which you should investigate through your Trek retailer if the structural integrity of the unit has been compromised.
