rim

The term "rim" primarily refers to the outer edge or border of an object. This can be seen in various contexts, such as the rim of a glass or the outer part of a wheel. In the context of technology, specifically for bicycles, the rim is a crucial component of the wheel. It holds the tire in place and connects to the hub via spokes. Bicycle rims come in various diameters and widths, and their cross-section is designed to accommodate different tire pressures and brake types. Rims are typically made from aluminum alloy or chrome-plated steel. The concept of "rim-drive" also exists, describing a method of driving a turntable through friction with its rim.1234
