A poorly fitted helmet is like an under-inflated tire in a curve: you feel it. At SHARK, we design helmets tailored for performance, but it all starts with a good fit. So, how do you know if your helmet is the right size? We tell you everything, without detours, so that your head stays well positioned whether you're in the middle of a circuit run or lane-splitting in the urban jungle.
Why the size of your helmet is crucial
The helmet is your best ally. It absorbs, protects, and allows you to stay focused on your line. But a poorly fitted helmet is a real risk:
- If it's too big: it can move in case of impact, reduce your visibility, or even come off during a crash.
- If it's too small: discomfort, painful pressure points, or even headaches after a few kilometers.
How to measure your head circumference
Let's start with the basics. To know your size, take a flexible measuring tape (or a string and a ruler):
- Wrap it around your head, just above your eyebrows and ears.
- Make sure it stays perfectly horizontal all around the skull.
- Note the measurement in centimeters. That's your head circumference.
Then compare with the SHARK size guide.
Signs of a well-fitted helmet
A good helmet is like a racing suit: it feels tight at first, but it adapts. Here are the checkpoints:
- It fits snugly without hurting: the helmet should exert even pressure, without painful points.
- It doesn't move: make a quick head movement from left to right. The helmet should not rotate independently.
- It doesn't fall over your eyes: your field of vision should remain clear.
- The hold is firm: even without a chin strap, the helmet should not easily slip backward when you tilt your head.
Trial: take the time to test
When you try on a helmet, keep it in place for at least 5 to 10 minutes. Your scalp will quickly tell you if there's a problem. The interior will slightly compress over time, so if it feels “perfect” from the first minute, it might become too loose after a few uses.
At SHARK, our models incorporate ergonomic comfort foams and precise adjustment systems. This helps to find a perfect fit for riding with confidence. The Best Fit technology is our answer to the quest for ultimate comfort and maximum safety. This innovation is based on a precise study of the human head's morphology across various profiles and sizes.
And if you're hesitating between two sizes?
Preferring a slightly smaller size, but still comfortable, is often recommended. A helmet that is slightly tight at first adapts better than a helmet that is too large and moves with every turn.
Finally, don't forget to check the chin strap's tightness. Good support also comes from there.
In summary: a helmet of the right size is:
- A feeling of firm support but without pain.
- A helmet that doesn't move when you shake your head.
- An optimal field of vision, without obstruction.
Take the time, measure, try, test. Your head deserves a helmet that fits. Because at SHARK, we don't compromise on safety, style, and performance.
