Bike helmet fit

  • Your helmet should sit level on your head, not tilted backward, to fully protect your forehead
  • When you shake your head from side to side, your helmet should not move more than 1/2″
  • You should be able to see the visor of your helmet, if you have one, when you look forward
  • The straps on the side of your head should form a V just under your ear lobes
