devices have been devised to hold a bike still to facilitate working on it, and they are usually called stands. Stands may clamp a part of the bike, such as the seatpost, seat tube, or top tube, or they may simply provide a surface on which a bike may rest with some security. Stands, especially those that clamp to a bike, may provide a means of repositioning a bike in order to conveniently locate the part being worked on. Stands may be either portable (light and collapsible) or fixed (heavy, usually attached to the floor, wall, or bench). Care must be taken with clamping stands not to clamp a part of the bike that cannot withstand the pressure, such as the tubes of many aluminum or carbon fiber frames, and non-cylindrical carbon fiber seatposts. An auxiliary bracket may be used with clamping stands to keep the steering mechanism from rotating. Storage Rack Bicycle storage refers to a method of storing bicycles indoors or outdoors to reduce space usage and protect bicycles. There are various ways to store bicycles, including using bicycle racks, hooks, vertical bike stands, bicycle storage cabinets, etc. Bicycle racks are one of the most commonly used bicycle storage devices. They are usually made of metal or plastic and can support the weight of the bicycle while lifting it up to save space. Bicycle racks can be placed on the ground or on the wall, allowing the bicycle to be hung up and not take up floor space. Hooks are also a common bicycle storage device. They are usually made of metal and can be fixed on the wall or ceiling. The benefit of using hooks is that the bicycle can be stored vertically, which saves more space. However, using hooks requires more effort to put the bicycle on and is not suitable for storing heavy bicycles. Vertical bike stands are a type of bicycle storage device that can store multiple bicycles. They are usually made of metal and can be placed on the ground, often in a corner of a garage or shed. This storage method is more space-saving than bicycle racks and can store multiple bicycles. Bicycle storage cabinets are an indoor storage solution for bicycles. They are usually made of wood, plastic or metal and can protect bicycles from weather and sun damage. They usually have locks to protect bicycles from theft and can reduce
