Frame bags are specialized storage solutions designed to fit within the triangular space of a bicycle's frame. They are typically made from durable materials and come in various sizes to accommodate different bike models. These bags provide a convenient way to carry essentials like tools, snacks, and personal items while keeping the weight low and centered for better balance. These bags are popular among cyclists, especially those who enjoy long rides or bikepacking. By utilizing the often-unused space in the frame, frame bags help maximize storage without compromising aerodynamics or handling. They can be easily attached and removed, making them a practical choice for any cyclist.
