Description The Quartz Rotor helmet stands out for one reason: the Rotor adjustment system. Rather than a standard ratchet, the Rotor dial gives precise, one-handed head size adjustment from 53–63cm — genuinely useful when you’re wearing gloves. The UV-resistant polypropylene shell handles outdoor exposure well, and the two possible headband positions (high/low) accommodate different head shapes more accurately than a fixed-position harness. Rated to 50°C/-30°C for extreme temperature environments.
