Triathlon bikes and time trial bikes are designed to be the most aerodynamic to minimize drag and make you as fast as possible. As the TT bikes look to slice through the air, comfort and weight are usually secondary and they tend to be heavier than a standard road bike. Popular with triathletes racing non drafting events like Ironman races, time trial bikes developed into tri bikes with integrated cables, integrated storage for hydration and nutrition, tri bars and a short head tube for a more aggressive position. The Scott Plasma series is a perfect example of triathlon bikes designed to allow you to achieve the best time and race against the clock.
