4. Setup
4.1. Helmet Fitting
- Measure Head Circumference: Use a flexible tape measure to find the circumference of your head, positioning it about 1 inch (2.5 cm) above your eyebrows and ears. The helmet is designed for adult head sizes between 21.3-24.4 inches (54-62 cm).
- Adjust the Dial System: Place the helmet on your head. Locate the easy-turn dial system at the back of the helmet. Rotate the dial clockwise to tighten the fit or counter-clockwise to loosen it until the helmet feels snug and secure without causing discomfort or pressure points.
- Adjust Straps: The helmet straps should form a 'V' shape just below your ears. Adjust the sliders on the straps to achieve this. The chin strap should be tightened so that the helmet does not move excessively when you shake your head. Ensure you can still breathe and swallow comfortably.
- Secure Buckle: Fasten the quick-release buckle under your chin. The buckle should be centered under your chin and tight enough so that no more than two fingers can fit between the strap and your chin.

4.2. Attaching/Removing the Brim
The flexible brim can be easily attached or removed to suit your riding style or preference. Align the brim's clips with the corresponding slots on the helmet and press firmly until it clicks into place. To remove, gently pull the brim away from the helmet.
4.3. Sunglasses Fit
The cycling sunglasses feature a wrap-around frame and non-slip nose pads. Place the sunglasses on your face, ensuring the nose pads rest comfortably on your nose bridge and the temples sit securely behind your ears. The design aims to prevent bouncing during activity.
