In timed events such as the pursuit and the time trial, riders often use aerobars or 'triathlon bars' similar to those found on road time trial bicycles, allowing the rider to position the arms closer together in front of the body. This results in a more horizontal back and presents the minimum frontal area to reduce drag. Aerobars can be separate bars that are attached to time trial or bull horn bars, or they can be part of a one-piece monocoque design. Use of aerobars is permitted only in pursuit and time trial events.
