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. [1]

Since the cyclist in a time trial is not permitted to draft (ride in the slipstream) behind other cyclists, reducing the drag of the bicycle and rider is critical. [2]

Time trial bicycles are similar to triathlon bicycles. Triathlon bicycles have a steeper seat tube angle, which pushes the hips forward and saves the hamstrings for the run. TT bicycles have to follow International Cycling Union (UCI) rules. UCI requires that the saddle nose of the TT bicycle must be 5 cm from the centre of the bottom bracket. [3]

An individual time trial (ITT) is a road bicycle race in which cyclists race alone against the clock. There are also track-based time trials where riders compete in velodromes, and team time trials (TTT). ITTs are also referred to as "the race of truth", as winning depends only on each rider's strength and endurance, and not on help provided by teammates and others riding ahead and creating a slipstream. Individual time trial are usually held on flat or rolling terrain, although sometimes they are held up a mountain road. Sometimes the opening stage of a stage race is a very short individual time trial called a prologue.

Cycling in Australia is a common form of transport, recreation and sport. Many Australians enjoy cycling because it improves their health and reduces road congestion and air pollution. The government has encouraged more people to start, with several state advertising campaigns aimed at increasing safety for those who choose to ride. There is a common perception that riding is a dangerous activity. While it is safer to walk, cycling is a safer method of transport than driving. Cycling is less popular in Australia than in Europe, however cyclists make up one in forty road deaths and one in seven serious injuries.

Time trials have been part of cycling for more than a hundred years. The first time trial was run in 1895 after a ban on road racing was imposed by the National Cyclists' Union. It wasn't until 1939 that the time trial made its world stage debut as an official stage of the Tour de France. It was originally used as a method of drawing more people to listen to the Grand Tour on the newly available radio broadcast of the 1939 race. The main thing that distinguished the first time-trial from the traditional form of road racing was that the riders started at intervals instead of one large group and they raced against the clock instead of each other. Unlike road racing where the a rider can hang in the peloton and draft off of other riders to conserve energy, time trial races put the rider out alone on the course. There are no breaks and no one to draft off, causing a rider to push as hard as they can the entire race. Bicycles have also evolved to accommodate this new form of racing, with most of the breakthroughs occurring in the last 40–50 years with the introduction of triathlons.
