Wheel: One of the more confusing terms when dealing with bikes is \wheel.” For a mountain bike, this term refers to the hub, spokes, rim, tube, tire, and, for rear wheels only, the cassette. All of these parts (with the exception of the tube, which is hidden inside the tire) are shown in Figure 1. Hub: Located at the center of each wheel.

The hub is connected to the frame of the bike by the skewer, which passes through the center of the hub. Cassette: The collection of gears to which the chain connects. The cassette is what allows the movement of the chain to turn the rear wheel. It is attached to the right-hand side of the hub. Spokes: The thin metal rods that make the wheel rigid and keep it from buckling. Each spoke attaches on one end to the hub and on the other end to the rim. Rim: The part of the wheel that supports the tire. It is made of metal (usually aluminum) and has a concave shape. The tube ts onto it, then the tire covers the tube. Tube: The part of the wheel that holds air. It is also sometimes called an inner tube. It is made of soft rubber, ts into the rim of the wheel, and is protected by the tire. A punctured tube is usually repairable with a patch kit, but replacing it is much faster and easier.
