Track bicycles, intended for high speed riding an indoor racing circuit which is exceptionally to reduce the weight. It is a fixed-gear bicycle that is used in a velodrome. It has narrow, light inflated tires with very high pressure. This happens by the cut down the rolling resistance caused by friction. They have a single gear mounted to a fixed hub no brakes, and are minimally adorned with other components that would otherwise be typical for a racing bicycle. Unlike road bicycles, used for road cycling, they lack multiple gears and brakes, having a single fixed gear ratio and no freewheeling mechanism. Tires are narrow, and as the track surface is very smooth there is no need for shock absorption, tires can be inflated to very high pressures well beyond those used in road cycling to minimise the rolling resistance caused by friction.
The frame Track bicycles are designed for track cycling according to use with ultra-simple, lightweight fixed-gear bikes with no brakes often in velodromes. The frames are inflexible used for sprinting, general racing etc. These frames are built up with several materials like steel, aluminum, carbon fiber and titanium. In fact most professional racers prefer this carbon fiber frame track bike. The frame track bicycles are similar to road bicycles but are differentiated by a more aggressive frame geometry that throws the rider into a more compact riding position. They also feature aerodynamic frames, wheels, and handlebars. It has common features like a high bottom bracket for corner clearance and a steeper seat tube to create an aerodynamic position for the rider. The track bike also boasts of a steeper head tube that aids in steering and a lower fork rake for stable steering at high speeds. It is very important to have a fixed gear ratio in track bicycles. The track cyclists are now able to change gears during the course of a race due to this fixed gear ratio. At its basic level, a change in gearing is a balance between quicker acceleration required for a ‘jump’ start and high top-end speed. A lower ratio allows quicker acceleration, or 'jump.' This can be crucially important in races where getting a gap on an opponent can be the deciding factor in the race. On the other hand, a high gear ratio makes easier to sustain a higher top-end if a cyclist is trailing somebody in the decisive stages of a race. Any how it helps in maintaining in standard high pace in the whole race. In a racing, the gear ratio is the most important key for a cyclist to have a quicker acceleration for a jump-start and to achieve higher top-end speed. There are two types of chains available like common widths for speed and fixed gear bicycle chains in form of 1/8 inch and 3/32 inch respectively. Most track bicycles use the wider, heavier 1/8 inch chain and also this standard chain is also used in BMX bicycles and in old-fashioned roadsters. Some track riders prefer the 3/32-inch chain for their bikes since they are lighter. Any how if you want to get best outcome, the chain ring, the sprocket and chain should all be of the same width.
