Triathlon bikes make up just a third of the overall challenge: swim, ride, run. That means they’re designed to minimise the amount of effort needed, so you can preserve your energy to make it to the finish line. How do they do this? They’re the ultimate aerodynamic machine, and they’re made to go fast. Everything about the bike, from the frame to the handlebars, is designed for absolute minimal wind resistance, and its aggressive riding position will make your quadriceps work harder, to give your hamstrings a break before that final push. The more you spend on a tri bike, the more lightweight and aero it will be.
