How to measure my size?
Helmet sizes are based on head circumference. Measure your size by wrapping a measuring tape snugly around the widest possible circumference - from the most prominent part of the forehead (often 1-2 fingers above the eyebrow) around to the widest part of the back of your head. Measure 3 times, and take the largest number. Using the chart above, select your size.
- Loosen the Zoom™ Spin rear dial before putting the helmet on.
- Position the helmet level on the head, sitting low across the forehead for the intended race fit.
- Adjust the internal rear cradle height using the side anchor positions to fine tune how the helmet wraps the back of the head.
- Lower cradle positions typically create a more secure, locked-in feel, while higher positions can relieve pressure depending on head shape.
- Tighten the rear dial gradually until the fit feels evenly secure around the head without pressure points.
- Fine tune the Flow Straps™ Pro so they sit comfortably below the ears in a clean “V” shape.
- The AirBreaker is designed for a close, race-oriented fit that should feel secure around the sides and back of the head while remaining lightweight and comfortable on long rides.
