A helmet that is too large will not stay in place during a crash. If your helmet is too tight, you may compromise its ability to properly disperse the force of an impact. Try on a helmet before you purchase it.
New helmets have an adjustment dial in the back to customize the fit. Tighten this dial enough so your helmet stays on without the chin strap when you bend forward.
Your helmet will not stay in place without clipping the chin strap. Adjust the strap, so you only have room to fit a couple fingers between the strap and your chin.
Bike helmets are designed to withstand only one impact. If you crash, replace your helmet. Even if you cannot see a crack, your helmet may be too compromised to withstand another crash.
Even if you do not crash, your helmet will wear down over time. Bell Helmets recommends replacing your helmet every three years.
