  • In-mold polycarbonate shell with EPS liner and thermoformed SL Roll Cage reinforcement provide serious protection
  • Roc Loc 5 fit system allows you to easily dial in fit tension and adjust vertical position with one hand
  • 26 vents with internal channeling keep you cool on the hottest rides

To find your size, position a tape measure just above your ears and about 1" above your eyebrows. Keep the tape level to measure the circumference around the largest part of your head and then find the corresponding size in the Specs below.

Will this helmet slide up in the front when wearing a cycling cap or beanie? Or will it stay firmly in place?

Asked by: David
The fit will vary based on your head shape and the thickness of the cycling cap/beanie.
