Bike frames

Bicycle frames - choose correctly in the Sportano shopThe bicycle frame is the basic structure on which the whole bicycle is based. It is the "skeleton" to which all other parts of the bicycle are attached, such as the wheels, saddle, handlebars or drive system. The frame defines the basic characteristics of the bicycle, such as its weight, stiffness and strength. The right frame construction is the key to comfort and riding efficiency, as well as resistance to damage in difficult conditions.Materials used in frame production: from steel to carbon fibre carbonEach material used for bicycle frames has its own specific properties that affect the riding experience, performance and durability of the bicycle. The choice of material is a key factor that determines how the bike will perform in different conditions. Steel is the classic material used for frames since the early days of bicycles. It is known for its strength, flexibility and ability to dampen vibrations, which translates into riding comfort. Steel frames are heavier than those made from more modern materials, but have the advantage of durability and ease of repair. For many riders, a steel frame also has a unique, "live" character. Aluminium became popular in bicycle frame manufacture in the 1980s and 1990s. Aluminium frames are lighter than steel frames, yet offer excellent stiffness. As a result, bikes on aluminium frames are more responsive. The disadvantage of aluminium is that it is less flexible than steel, which can lead to a stiffer ride. Carbon fibre is a relatively new material in the world of bicycles, but it has quickly gained popularity among road and mountain bikers. Carbon fibre is extremely light and stiff, which means that carbon fibre frame bikes offer phenomenal performance. In addition, carbon fibre has the ability to dampen vibrations, which increases riding comfort.Frame geometry: the effect of shape on riding characteristics RidingThe frame geometry plays a key role in how the bike reacts to the rider's movements, as well as how the rider feels on the bike. The right frame shape and size have a direct impact on comfort, handling and overall riding performance. The angle of the head tube determines how steeply the bike enters corners. A sharper head angle makes the bike more agile, but less stable at high speeds. Conversely, a flat head angle increases the stability of the bike, but makes it less agile. Wheelbase affects the overall length of the bike. A short wheelbase leads to a fast and agile ride, while a longer wheelbase increases the stability of the bike, especially on descents. The height of the bottom bracket determines the bike's centre of gravity. A lower bottom bracket makes the bike more stable, but increases the risk of hitting the pedal on the ground when riding over rough terrain. The length of the seat tube and the angle of the seat tube affect the rider's seating position. This position is crucial for riding comfort and the efficiency of power transfer from the rider's legs to the wheels. Understanding frame geometry is crucial for anyone who wants to fine-tune their bike to suit their needs. A well-designed frame tailored to the rider's individual requirements can significantly improve the riding experience.Frame types: from road to mountain to urbanBicycle frames, like bicycles themselves, have been developed to suit different riding styles and the different conditions a cyclist may find themselves in. Choosing the right type of frame for a particular application is crucial for comfort, performance and riding safety. Road frames are true gems among bikes designed for smooth surfaces. They are characterised by lightweight, aerodynamic shape and aggressive geometry to minimise drag and maximise speed. They are usually made from high quality materials such as carbon fibre or aluminium to provide adequate stiffness at the lowest possible weight. For many road cyclists, the frame is the heart of their machine and its precise construction is a guarantee of sporting performance. Mountain frames, on the other hand, are designs adapted to more difficult terrain. Durability, shock absorption and versatility are their main strengths. They can be fitted with special mounting points for front and rear shock absorbers. The materials used for mountain frames must be impact resistant, so steel, aluminium and sometimes carbon constructions are often found here. Riding off-road presents completely different challenges to a mountain frame than a fast ride on the flat, so their construction is different. Urban frames, on the other hand, are designed with comfort and functionality in mind. They often have a more upright geometry that promotes a more comfortable riding position. They can be fitted with additional features such as racks, basket holders or mudguards. The materials used in the production of urban frames must combine strength with low price, so steel constructions are often found here. The urban landscape is full of unexpected challenges, from uneven pavements to kerbs and level crossings, and a properly designed urban frame can overcome these challenges.
