A time trial bicycle is a

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

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]
