A triathlon bike is a specialized bicycle designed for the sport of triathlon, which combines swimming, cycling, and running. These bikes are built for speed and efficiency, featuring a lightweight frame and aerodynamic design. They often have a more aggressive riding position to reduce wind resistance, allowing athletes to maintain higher speeds during the cycling segment of the race. Triathlon bikes typically come with specific components, such as aero handlebars and a single chainring, to enhance performance. Unlike traditional road bikes, they prioritize aerodynamics over comfort, making them ideal for competitive events. Proper fit and adjustments are crucial for maximizing efficiency and minimizing fatigue during a triathlon.
