One of the bigger differences between a road bike and a triathlon bike is related to aerodynamics.
The most obvious difference is related to body position of the riders. When we view the diagram below we can see quite clearly that the Triathlon rider is in the most aerodynamic position. The Road Racer is in the next most aerodynamic body position. If you want to be a competitive triathlete getting into the most aerodynamic position possible is a huge advantage.
At Tri Bike Upgrade we can help get you onto a Tri bike that will help you maximize the time that you have put into training.

Being as aerodynamic as possible is about more than just the bike and the body position.
