Once you are wearing the helmet, if it is not comfortable and stable on your head, or you are unsure about the fit, follow the below steps to check;
1. Adjust the Fit/Stabilizing System
For safety reasons, we recommend that you do not attempt to adjust the fit of a helmet while you are riding.
To adjust the fit tension of the fit/stabilizing system while the helmet is on the wearer’s head, simply rotate the dial adjuster on the back of the system to tighten or loosen the fit as needed. You can adjust the fit even more on helmets with systems that offer height adjustment, which allows the helmet’s fore/aft tilt to be optimised. Simply move the system’s occipital pads (at the back of the helmet) up or down for comfort and the best coverage. Experiment until you get a fit that is most comfortable.
2. Adjust the Straps at the Ears
With a proper fit, the front and rear straps should join at a point slightly below the ears. To adjust the strap positioning, open the adjusters on the straps around the ears, put the helmet on and slide the straps through the adjusters until they are located comfortably under the ears. Make sure there is no slack in any of the straps. Finally, make sure the adjusters are secured.
3. Adjust the Helmet’s Chinstrap and Buckle
Fasten the chinstrap buckle and tighten the straps until the helmet fits snugly. How snugly? You should be able to open your mouth wide enough to eat. Make sure the chinstrap is well back against the throat, NOT on the point of the chin. Straps worn on the point of the chin increase the chance of a helmet coming off in an accident. Make sure the loose ends of the strap pass through the rubber O-ring near the buckle. If it does not, the strap may slide loose and the helmet can come off accidentally. Always wear the helmet with the chinstrap buckle fastened and the strap pulled tight.
4. Check for Proper Fit
Once you think a proper fit has been achieved, grab the helmet with both hands and twist lightly it to the left and right. If the helmet fits properly, the skin on the forehead will move as the helmet moves. If it does not, the helmet is too loose.
Next, grab the helmet with both hands and try to remove it by rolling the helmet forward and backward.
THIS IS IMPORTANT. If you can roll it off the head completely, roll it so far forward that it blocks vision, or backward far enough to expose the forehead, it doesn’t fit correctly. If you cannot adjust the helmet to fit properly according to these instructions, DO NOT USE THE HELMET. Replace it with a different size or model.
Once you are satisfied that the helmet fits correctly and that all straps are properly adjusted, take a short test ride. Make any minor adjustments to improve comfort and stability. If you have questions about fit, please get in touch.
