Used in a velodrome, a track bicycle is a fixed-gear bicycle. Besides those used in road cycling, it has narrow light tires that are inflated to a very high pressure, to cut down the rolling resistance caused by friction. To minimize skidding chances the tires used by track cyclists for grass have knobs. Because they are puncture proof they rarely get punctured.

According to use, bicycles frame tracks can vary. Frames used in sprinting are rigid and those used for general racing and longer events are aerodynamic. Several materials like steel, aluminum, carbon fiber and titanium are used in making the frame. Carbon fiber is used by most professional racers while steel is used by non-track riders. Bottom bracket for corner clearance and steeper seat tube to create aerodynamic position for the rider are common features form most track frames. For stable steering at high speeds is added a lower fork rake and also for steering the bike boasts of a steeper head tube.

Gear ratio is important because track cyclists are unable to change gears during the course of a race. To strike a balance between quicker acceleration required for a jump start and high top-end speed is the criteria to select a gear ratio. Lower gear ratio leads to quicker acceleration for a jump start in a race.

A high gear ratio, on the other hand, is used if a cyclist is trailing somebody in the decisive stages of a race because helps maintaining constant high speed trough the whole race. For racing, quicker acceleration ratio gear is recommended, because it provides a jump-start the achievement of higher top-end speed.

Single speed and fixed gear bicycle have two common width chains of either 1/8 of an inch or 3/32 of an inch. Most track bicycles (including BMXs) and roadsters use the 1/8-inch chain because it’s wider and heavier. Since the 3/32-inch chain is lighter some track riders prefer it. The chain ring, the sprocket and the chain should all be of the same width.
