Road Bicycle Components
a racing bicycle, also known as a road bike, is a bike designed for competitive road cycling, a sport influenced by according to the principles of Union Cycliste Internationale (UCI). The UCI rules had been changed in 1934 to exclude recumbent bicycles.
The main characteristics about a racing bike are its body weight and tightness which determine the performance of which the energy from a driver's pedal shots is used in the drive-train and later to its rims. To this impact rushing bikes may sacrifice comfort for speed. The fall handlebars are placed lower than the saddle to be able to put the rider in a more aerodynamic position. Leading and straight back rims are close together so the bike has quick control. The derailleur gear ratios tend to be closely spaced so your rider can pedal at their maximum cadence. Various other rushing bikes, particularly those found in time trialling, prioritize aerodynamics over convenience.
Distinction between race bicycles and others
Bikes for racing on velodromes are track bicycles; bicycles for racing offroad tend to be mountain bikes, cyclo-cross bikes or pattern speedway bicycles; bicycles that race based on the guidelines for the Global Human Powered Vehicle Association feature faired recumbent bicycles which, on flat surface, would be the quickest bikes in the field. Recumbents had been excluded from UCI concept of a bicycle on 1 April 1934.
Time trial bicycles are a subset of racing bikes that are made for time trial events. The UCI principles of these bikes tend to be somewhat less prescriptive than those for "massed begin road races" (see rules 1.3.020 to 1.3.023).
Triathlon bicycles tend to be governed by Overseas Triathlon Union (ITU) rules, which enable more modern technical developments than perform some UCI guidelines.
The framework of a racing bicycle must, in accordance with the UCI regulations, be constructed making use of a "main triangle" with three straight tubular shapes—the top pipe, down pipe, and chair tube. These three tubes, also areas of the frame, need not be cylindrical, however, and many race bicycles function structures which use alternative shapes. Typically, the very best tube of a racing bike is close to parallel with the ground if the bike is in its typical upright position. Some rushing bicycles, but have a high pipe that mountains down to the back of the bike; the "small" framework geometry ended up being popularized by Giant.
Frame makers are able to utilize any material they choose into the framework. For the majority of associated with the reputation for road racing, bike frames had been manufactured from metallic tubing, and aluminium and titanium alloys were in addition made use of effectively in racing bicycles. Rushing bicycles within these three products remain commercially readily available and are usually nevertheless employed by some amateur race cyclists or in vintage racing classes. But most expert road racing cyclists now make use of frames made out of numerous carbon dietary fiber composite materials, and an average contemporary carbon fibre framework weighs significantly less than 1 kg (2.2 lbs).
