Using the Bell Super 3R MIPS Helmet is easy. First, adjust the Float Fit system using the rubber over - moulded dial to get a comfortable fit. You can use the No - Twist Tri - Glides for finer adjustments. When you start a long climb, simply remove the chin bar by following the tool - free process. Keep it in your pack. When you reach technical parts of the trail, lock the chin bar back in place. The goggle and sunglasses guides are there to help you keep your eyewear in position. The adjustable visor can be set to block the sun as you like. You can also attach a camera to the breakaway mount. Remember to always wear the helmet properly on your head. For maintenance, clean it with a mild soap and water. Don't use harsh chemicals. After cleaning, let it dry naturally. Check the helmet regularly for any signs of damage, and replace it if needed.
