Triathlon / TT
A time trial bicycle is a racing bicycle designed for use in a Triathlon or in an individual or team time trials raced on roads.
Since the cyclist in a time trial is not permitted to draft (ride in the slipstream) behind other cyclists, reducing aerodynamic drag of the bicycle and rider is critical. One difference between a time trial bicycle and a road bicycle is the use of triathlon handlebars or aerobars. The main part of the bullhorns curves forward (like a road handlebar), but where the road handle bar curves down, the time trial bar ends. This provides a low tucked position that is aerodynamic while providing good stability. The time trial bar also uses a “clip on” bar or aerobar which attaches to the main bar near the stem and provides a position where the hands and fore-arms are close together, low and forward, providing a very aerodynamic (though less stable) position.
