• Reduce wind resistance.
• Protect the skin against the repetitive friction of the legs against the bicycle seat or frame.
• Draw sweat away from the skin to prevent chafing and rashes, and to cool the rider down from the process of evaporation
• Compress the legs, which can help combat muscular fatigue.

Historically, cycling shorts were made with black wool and a leather chamois patch inside the shorts in the seat and crotch area. Most modern cycling shorts are made with spandex (lycra) with a synthetic chamois lining, and are produced in a variety of shapes and styles to suit the needs of different riders. For example, the patterns used for the chamois on women's cycling shorts tend to be quite different from those used for men's.[1] The hem of each leg is usually lined with a ring of material that clings to the skin, keeping it in a fixed position. They are designed to be worn alone with no undergarments or as an undergarment. Shorts made from more panels (or cuts of fabric) fit better, but cost more.

Short-legged elastic tights commonly worn as street wear or for gymnastics and ballet practice are sometimes also referred to as cycling shorts, but are typically simpler and lighter garments than those worn by cyclists.

Bibs

Bibs are cycling shorts which are held up by a bib (like suspenders) instead of an elastic waistband. Pro and serious riders tend to prefer bibbed shorts over non-bibbed shorts due to discomfort that often occurs with the elastic waistband, such as tightness (digging into skin) and chaffing. The bib part of the short is made of spandex and polyester with large sections of netting to help cool down the rider.

The idea of modern bib shorts seems like it evolved from the braces (UK) or suspenders (US) that cyclists used to use to hold up old fashioned wool shorts which had a tendency to become loose and heavy from riders sweat (the use of bibs meant the shorts could be held up without an uncomfortably tight waistband). On the other hand, the design, past or present, seems logical. Bib shorts are more ideal for tall riders or riders with protruding stomachs, because regular shorts can tend to fall down at back while riding.
