The Concept behind a Triathlon Bike
A triathlon bike is one of the most impressive designs in the arena of racing bikes, as you are about to discover. The entire premise of this bike design has to do with aerodynamics needed for speed. Although people who compete in triathlons could use a road bike or other type of racing bike, the triathlon bike is without doubt the best because it is made specifically for this type of event. With the aerodynamic design, the bike is capable of resisting wind so riders are able to reach incredible speeds.
One of the most fascinating design aspects of the triathlon bike is the handlebars. Called aero bars or tri-bars, these handlebars actually put the rider at a lower profile so wind reduction is achieved. Interestingly, the handlebar design was based on a geometry formula created back in the 1980s and over the years, modifications have been made to where today, this is a critical part of the overall bike design.
Another component that makes up the triathlon bike is the frame tubes. These are created in a teardrop or oval cross-section shape, again for the ultimate in aerodynamics. Other features associated with a triathlon bike include wheels with few spokes or carbon fiber tri-spokes, innovative frames, and specially angled seats.
Generally, the triathlon bike is referred to as an aggressive bike and for good reason. The angles, handlebars, and low stem all work together as a team in perfect alignment to the saddle. As a result, aerodynamic capabilities are magnified. What happens is that the rider’s torso is lowered so the overall profile becomes much smaller and therefore, more wind resistant. In addition, the way in which the triathlon bike positions the rider, he or she actually uses less strength and energy, which means muscle power is being preserved for the running portion of the triathlon.
