Adaptive cup holder Flexible grille structure automatically adjusts to different cup diameters, providing a safe grip for various water bottle sizes. Designed for cyclists who frequently switch bottles during rides, offering convenient bottle changes without removing the holder. 360 degree rotation Fully rotating mechanism design allows you to adjust the bottle direction at any angle. Flexible positioning enables quick orientation changes to suit riding style and access preferences. Stable and secure Clip design is easy to install on compatible mounts. On rough surfaces, an automatic tightening system firmly fixes the bottle in place, reducing vibration and preventing displacement during speed riding. Geometric pattern design and ventilation Geometric pattern enhances the overall structure and channels airflow around the bottle. The ventilation design helps reduce heat absorption, helping beverages stay cooler longer during outdoor activities. Use scenarios Long cycling trips with multiple bottle sizes: switch bottles midride without stopping, while the holder maintains a secure grip. Rough terrain or fast descents: enhanced stability minimizes bottle movement and reduces the risk of spills. Outdoor activities and daily commuting: keeps beverages cooler for longer periods while exposed to sun or heat.
