There are so many types of bicycles and parts, equipment and accessories that it’s easy to get lost. Manufacturers are constantly innovating and competing with originality in order to stimulate the consumer. Is a triathlon bike really necessary for a triathlete? Frame or wheels, what is the best investment for a cyclist? How to choose a bicycle saddle? Manufacturers often make cyclists claim the wonderful effects of their products. Can a compression port really improve performance and speed recovery? Is a power sensor important for a serious rider? After reading this section, you can make a more informed choice regarding equipment.
City bikes are characterized by curved handlebars, 700 mm wheels, narrow tires from 18 to 25 mm and a frame made of lightweight carbon, aluminum or titanium. The weight of road bikes is from 5 to 10 kg, but for competitions I set their minimum weight to 6.8 kg. Triathlon and time-controlled bikes are more aerodynamic options for a road bike. The most recognizable features of these two types of bicycles are a handlebar extension, a frame with a more vertical seat angle and aerodynamic wheels such as high-profile wheels, solid wheels or club wheels.
Mountain road bikes look like a road bike, but it’s less fragile than the last. Its frame, usually made of steel, is heavier than that of a road bike, and its wheels are reinforced. It has front and rear struts and a saddle, the first quality of which should be comfort. The mountain bike is intended for routes and rough roads. It is often equipped with a dual damping system. Wide tires with spikes for maximum traction are mounted on wheels with a diameter of 26 to 29 inches.
The mountain bike also has a rather low frame, straight handlebars and gear ratios to facilitate steep climbs. A hybrid bike and a cyclo-cross bike are a mix of road and mountain bikes. They are equipped with 700 mm wheels as a road bike, but the tires are slightly wider. A hybrid bike has a direct handlebar, while a bike with a curved handlebar has a curved handlebar. A hybrid bike is usually used for active transportation, while a cyclo-cross is intended for an athlete who wants to perform in various types of terrain.
Fatbike is an off-road motorcycle with large tires that deform when in contact with obstacles and can overcome any type of terrain. Moreover, it stands out especially in the snow and sand. This heavyweight (12 to 17 kg) is equipped with a rigid frame without suspension. Single speed and fixed gear bikes are single sprocket bikes. Unlike a single-speed engine, the crank mechanism of a fixed-gear bicycle is associated with the rotation of the rear wheel. The popularity of these types of bicycles has increased in recent years among urban cyclists. Materials used Carbon fiber is very lightweight, corrosion resistant and efficient for energy transfer. In addition, it can be modeled to create aerodynamic bicycles. However, it is fragile and expensive. Aluminum is extremely tough, lightweight and inexpensive. Aluminum bicycles provide excellent power transmission, but the low ability to absorb this metal makes it sensitive to road vibration.
Steel is a popular and traditional material that makes bicycles comfortable, durable and affordable. It is easy to repair, but, in turn, it is heavier and susceptible to corrosion. Titanium is lightweight, flexible, durable, very durable and stainless. However, it is much more expensive and, unfortunately, it can be for those who like to regularly change their frame … for life! Bamboo is an environmentally friendly, durable material that absorbs vibration and shock. His characteristics will allow him to one day compete with the most popular metals.
The ratio is the ratio of the number of teeth of the lower bracket to the gear of the rear wheel. For example, a large gear is associated with a combination of a large plate and a small gear; the hose is a tire, the inner tube of which is wrapped inside and glued to the rim (part of the wheel in contact with the tire);
Mover of a bicycle. A bicycle mover is the result of opposing forces: internal forces (muscle contractions) that allow the cyclist to pedal, and external forces (air resistance, gravity and friction) that interfere with his displacement.
