Triathlon and time trial bikes are quite expensive and not wonderful to ride on open courses, hills, and in groups (in other words, general cycling).



So, if you're not so serious about triathlons that you're willing to spend several thousand dollars on a bike that will see relatively little use, you'll likely be content with your existing road bike whose handling and fit works well with your body and riding style.






share|improve this answer























  • I have limited personal experience, but based on people I've talked to it takes dedicated training on the time trial bike to become good/experienced enough for the bike to be a worthwhile investment. So there's the training cost to consider in addition to the monetary cost.

  • All of the videos were of either pro's or elite amateurs. The road bikes in the videos were carbon with deep section carbon wheels, easily over $6K. So these are serious competitors who would have been using a TT bike if it was the right tool.

The videos linked were road bikes were used were of pros or elite amateurs who will have multiple bikes and would be using a Time Trial (TT) bike if it was the right tool.



Originally, all triathlons used to have a no-drafting policy, which made optimizing your personal aerodynamics critical. Hence the rise of TT bikes in the early history of triathlons.



Relatively recently drafting has been made legal in many short track triathlons, making TT bikes both dangerous and not suitable for the format. When you have drafting you essentially have a road race, which a road bike is the right tool. Quick handling is key as you need to be able to maneuver and keep your front wheel within 2-6 inches of the bike you are drafting in order to get the full draft effect. You also need to be able to accelerate, brake, and change direction quickly to close gaps and respond to group dynamics. Groups can at times move incredibly fast, 65 kph on the flat is not uncommon for pros or elites.



In contrast, Ironman events still have no-drafting rules in place making TT bikes the right tool as its about individual riders against the wind and not responses to group dynamics.
