Gross Anatomy: Identifying the Parts of a Bike

Figure 2-1 identifies the different parts of a road bike, and Figure 2-2 illus­trates many of the same parts — and a few differences — on a mountain bike.

Gross Anatomy: Identifying the Parts of a Bike

Not all bikes are the same, and some parts vary from bike to bike —road bikes are different from racing bikes, which are different from touring bikes and mountain bikes. A road bike has thin tires, light weight, and is built for smooth, pavement riding. Somewhat similar in appearance to a road bike is a racing bike; racing bikes are designed with expensive, lightweight materials and with a premium on aerodynamics (for example, with handlebars that are positioned lower than they are on a road bike). A mountain bike is easy to spot with its thick knobby tires, suspension, and heavy disk brakes to sup­port riding on trails and rough terrain. A touring bike looks very similar to a road bike but usually has a wider wheelbase, a greater range of gears, and racks to carry pannier bags.

These two diagrams give you the basics on two of the most popular types of bikes, road and mountain bikes; for information specific to your specific bike, check out the manual that came with it.
