I always recommend wearing a helmet. A helmet can definitely save your life and it can definitely
prevent major brain injury. Helmets are designed to crack on impact. They're not designed to
remain intact. What they're designed to do is as you hit the cement or pavement, they're
going to crack transferring the energy of the impact into the helmet away from your
skull. Helmets are engineered to pass one specific safety test. After they've pass that
test, they're certified. And what you're really paying for after that is desirability, lightweight,
ventilation, that sort of thing. Helmets are going to range in price from $49 to $300.
They're also going to come in about three different sizes. A good way of determining
which size works for you is measuring your head. They're going to be measured in centimeters.
This is what's known as a traditional road helmet. It adjusts in the back to become tighter
and looser. It's well ventilated and it's relatively light. This is what's known as
a time trial helmet. It's going to be far more aerodynamic. It's going to be a little
bit heavier, a lot less vents. It's built for time trials and triathlons. You're not
going to find this in road racing. It's not legal to race with this, but it makes a big
difference if you are time trialing or if you're in a triathlon. Riding without a helmet
is just plain dumb and I really, really recommend always riding with your helmet.
