Time trial bikes used by the Astana team in 2015. A time trial bicycle is a racing bicycle designed for use in an individual race against the clock. Compared to a road bike, a time trial bike is more aerodynamic, has a shorter wheelbase, and puts the rider closer to the front of the bicycle. It may have either a solid disc or spoked wheels.
Component groups are fairly universal on road bikes and time trial bikes. Both use the same group-sets and depending on the rider and the venue of the practice or race, the same gearing might also be used. The cranks are the main component difference between road and time-trial bikes. A standard crank, which is found on road bike, has two chain ...
Triathlon played a key role in the development of cycling with an aero geometry during the 1980s. Aerobars are used in other forms of cycling, such as time trials and some events in track cycling. Instead of the familiar curved "drop bars" of road bicycles, aerobars are mounted to a set of "pace bars" or "bull-horns".
Flatland rider on a BMX bike. Road racing bicycles.

Triathlon bicycles have seatposts that are closer to vertical than the seatposts on road racing bicycles.

Individual time trial are usually held on flat or rolling terrain, although sometimes they are held up a mountain road (in Italian: cronoscalata "chrono climbing"). Sometimes the opening stage of a stage race is a very short individual time trial called a prologue (8 km or less for men, 4 km or less for women and juniors).
Track time trial bikes differ from normal track bikes in two major ways; firstly they have disc or 3–5 spoked wheels, and secondly they often use aero-bars to allow the rider to adopt a more aerodynamic riding position. The frames are often more streamlined to reduce air resistance.
Reducing the weight of the bike + rider by 1 kg would increase speed by 0.01 m/s at 9 m/s on the flat (5 seconds in a 32 km/h (20 mph), 40-kilometre (25 mile) time trial). The same reduction on a 7% grade would be worth 0.04 m/s (90 kg bike + rider) to 0.07 m/s (65 kg bike + rider).
