Cone Wrench
A cone wrench or cone spanner is a tool used in bicycle assembly and maintenance to adjust the cones of cup and cone bearings. Cone wrenches are thinner and lighter than most other open ended wrenches that are used to work on bicycles. They should be used only for making adjustments to cones or for other low torque applications such as centering brakes. Using a cone wrench in high torque applications such as loosening outer axle nuts may easily damage the wrench. Cone wrenches are typically about 2 mm thick, compared to approximately 7 mm for a standard open-ended wrench. Cone wrenches are commonly sized between 13mm and 28mm. The sizes most commonly used today are 13, 14, 15, 16 and 17mm. Most sizes 19mm and above are used for specialty applications such as BMX and internally geared hubs.

Bicycle
A bicycle, also called a pedal cycle, bike or cycle, is a human-powered transport, human-powered or motorized bicycle, motor-powered assisted, bicycle pedal, pedal-driven, single-track vehicle, having two bicycle wheel, wheels attached to a bicycle frame, frame, one behind the other. A is called a cyclist, or bicyclist. Bicycles were introduced in the 19th century in Europe. By the early 21st century, more than 1 billion were in existence. These numbers far exceed the number of cars, both in total and ranked by the number of individual models produced. They are the principal means of transportation in many regions. They also provide a popular form of recreation, and have been adapted for use as children's toys, Physical fitness, general fitness, military and police applications, courier services, bicycle racing, and bicycle stunts. The basic shape and configuration of a typical Safety bicycle, upright or "safety bicycle", has changed little since the first Chain drive, ...

Cup And Cone Bearing
The rolling-elements of a rolling-element bearing ride on races. The large race that goes into a bore is called the ''outer race'', and the small race that the shaft rides in is called the ''inner race''. Design In the case of ball bearings, the bearing has inner and outer ''races'' and a set of balls. Each race is a ring with a groove where the balls rest. The groove is usually shaped so the ball is a slightly loose fit in the groove. Thus, in principle, the ball contacts each race at a single point. However, a load on an infinitely small point would cause infinitely high contact pressure. In practice, the ball deforms (flattens) slightly where it contacts each race, much as a tire flattens where it touches the road. The race also dents slightly where each ball presses on it. Thus, the contact between ball and race is of finite size and has finite pressure. The deformed ball and race do not roll entirely smoothly because different parts of the ball are moving at different spe ...

Wrenches
A wrench or spanner is a tool used to provide grip and mechanical advantage in applying torque to turn objects—usually rotary fasteners, such as nuts and bolts—or keep them from turning. In the UK, Ireland, Australia, and New Zealand ''spanner'' is the standard term. The most common shapes are called ''open-ended spanner'' and ''ring spanner''. The term ''wrench'' is generally used for tools that turn non-fastening devices (e.g. tap wrench and pipe wrench), or may be used for a monkey wrench—an adjustable pipe wrench. In North American English, ''wrench'' is the standard term. The most common shapes are called ''open-end wrench'' and ''box-end wrench''. In American English, ''spanner'' refers to a specialized wrench with a series of pins or tabs around the circumference. (These pins or tabs fit into the holes or notches cut into the object to be turned.) In American commerce, such a wrench may be called a ''spanner wrench'' to distinguish it from the Britis ...
