Using your Fatbar Lite 35 handlebar is easy. First, make sure to align the handlebar properly using the laser - etched positioning grid at the stem clamp area. You can then adjust the width according to your preference with the help of the width marks. When riding, this handlebar will give you a great grip and control for all types of cycling. As for maintenance, keep it clean by wiping it down with a soft cloth after each ride. Avoid using harsh chemicals that could damage the anodized finish. If you notice any signs of corrosion or damage, it's best to have it checked by a professional. And always remember to check the tightness of the clamp regularly to ensure your safety on the road or trail.
