Jalgratased

Jalgratased refers to bicycle wheels. A bicycle wheel is a component that allows a bicycle to roll and be steered. It consists of a hub, spokes, rim, and tire. The hub is the central part of the wheel that rotates on an axle. Spokes connect the hub to the rim, providing structural integrity and distributing the load. The rim is the outer circular part to which the tire is attached. The tire, typically made of rubber, provides traction and cushioning.

Bicycle wheels come in various sizes, commonly measured by their diameter. Common sizes include 26 inches, 27.5 inches (also known as 650b), 29 inches (or 700c for road bikes), and smaller sizes for children's bikes. The choice of wheel size can affect a bicycle's handling, rolling resistance, and maneuverability.

The construction of bicycle wheels also varies. Spoke patterns, such as radial lacing or crossed lacing, influence the wheel's strength and stiffness. Rims can be made from materials like aluminum or carbon fiber, each offering different weight and durability characteristics. Tires can be tubed or tubeless, with tubeless systems offering advantages like reduced weight and fewer pinch flats. The inflation pressure of the tire is crucial for ride comfort, rolling efficiency, and grip. Properly inflated jalgratased are essential for a safe and enjoyable cycling experience.
