Skirt guard or coatguard: a device fitted over the rear wheel of a bicycle to prevent a long skirt, coat or other trailing clothes or luggage from catching in the wheel, or in the gap between the rim and the brakes; Spindle: an axle around which a pedal rotates; threaded at one end to screw into crank arms; Spoke: connects wheel rim to hub ...
However, now, bigger versions of the heavy-duty tire changers are designed to mount/demount tires up to 95 inches (2.4 m) in diameter and also feature a hydraulically operated self-centering four-jaw chuck with clamping jaws that can clamp from 14 to 58 inches (0.36 to 1.47 m) either from the wheel’s inside or from the center bore.
Tire bead jack can be used to install tires on rims, especially when the tire-rim combination is tight. Dishing gauge is used to measure the dish of a wheel. Wheel truing stand is used to measure the side to side and radial trueness of a wheel's rim and facilitate truing it. Bicycle pump; Pressure gauge is used to measure tire pressure.
A tire bead is held in the groove by air pressure. A bead breaker is a tool used for separating tires from rims. The innermost diameter of the tire that interfaces with the rim of a wheel is called the tire bead. The bead is a thicker section of rubber, and is reinforced with braided steel cables, called the bead bundle. [1]
To change gear: stop, remove the rear wheel, flip it over, replace the wheel, adjust chain tension, resume cycling. Current double sided wheels typically have a fixed sprocket on one side and a freewheel sprocket on the other. Prior to 1937 this was the only permitted form of gear changing on the Tour de France.

Bicycle chains Roller chain and sprocket. A bicycle chain is a roller chain that transfers power from the pedals to the drive-wheel of a bicycle, thus propelling it.Most bicycle chains are made from plain carbon or alloy steel, but some are nickel-plated to prevent rust, or simply for aesthetics.
Braze-on: An alternative to the clamp is the braze-on derailleur hanger, where the derailleur is mounted by bolting a tab on the derailleur to a corresponding tab on the frame's seat tube. This avoids any clamp size issues, but requires either a frame with the appropriate braze-on, or an adapter clamp that simulates a braze-on derailleur tab.
Tire maintenance for motor vehicles is based on several factors. The chief reason for tire replacement is friction from moving contact with road surfaces, causing the tread on the outer perimeter of tires to eventually wear away. When the tread depth becomes too shallow, like for example below 3.2 mm (4/32 in), the tire is worn out and should ...
