Cycling shoes are shoes purpose-built for cycling. There are a variety of designs depending on the type and intensity of the cycling for which they are intended. Key features include rigidity, for more-efficient transfer of power from the cyclist to the pedals, weight, a method of attaching the shoe firmly to the pedal and adaptability for use on and off the bicycle. Most high performance cycling shoes can be adjusted while in use, via a quick-adjusting system that has largely replaced laces.
Artificial leather is a fabric or finish intended to substitute for leather in fields such as upholstery, clothing, and fabrics, and other uses where a leather-like finish is required but the actual material is cost-prohibitive, unsuitable, or unusable for ethical reasons.
An optical fiber (or optical fibre) is a flexible, transparent fiber made of glass (silica) or plastic, slightly thicker than a human hair. It functions as a waveguide, or “light pipe”,to transmit light between the two ends of the fiber. The field of applied science and engineering concerned with the design and application of optical fibers is known as fiber optics. Optical fibers are widely used in fiber-optic communications, which permits transmission over longer distances and at higher bandwidths (data rates) than other forms of communication. Fibers are used instead of metal wires because signals travel along them with less loss and are also immune to electromagnetic interference. Fibers are also used for illumination, and are wrapped in bundles so that they may be used to carry images, thus allowing viewing in confined spaces. Specially designed fibers are used for a variety of other applications, including sensors and fiber lasers. Optical fibers typically include a transparent core surrounded by a transparent cladding material with a lower index of refraction. Light is kept in the core by total internal reflection. This causes the fiber to act as a waveguide. Fibers that support many propagation paths or transverse modes are called multi-mode fibers (MMF), while those that only support a single mode are called single-mode fibers (SMF). Multi-mode fibers generally have a wider core diameter, and are used for short-distance communication links and for applications where high power must be transmitted. Single-mode fibers are used for most communication links longer than 1,050 meters (3,440 ft). Joining lengths of optical fiber is more complex than joining electrical wire or cable. The ends of the fibers must be carefully cleaved, and then spliced together, either mechanically or by fusing them with heat. Special optical fiber connectors for removable connections are also available.

A mountain bike or mountain bicycle (abbreviated MTB) is a bicycle created for off-road cycling. This activity includes traversing of rocks and washouts, and steep declines, on dirt trails, logging roads, and other unpaved environments—activities usually called mountain biking. These bicycles need to be able to withstand the stresses of off-road use with obstacles such as logs and rocks. Wheels used on mountain bikes usually use wide, knobby tires for good traction on uneven terrain and shock absorption.

Zip fastener
A zipper, zip, or zip fastener, is a commonly used device for temporarily joining two edges of fabric. It is used in clothing (e.g., jackets and jeans), luggage and other bags, sporting goods, camping gear (e.g. tents and sleeping bags), and other items.
