Looking for something to ride after you swim? The purpose of any bike is heavily influenced by its geometry and triathlon bikes are no exception. Triathletes need to be comfortable for long periods of time in an aerodynamic position and be able to run long distances once off the bike. As such, the seat tube angle and top tube length are the two key differences between triathlon bikes and road bikes that are aimed at recruiting different muscle groups and providing comfort without sacrificing performance.
All good triathlon bikes start with a proper fit. A ultra aggressive positioning is great for aerodynamics but can be hard to maintain for long periods of time, especially for those lacking the flexibility and mobility through their hips and lower back. To combat this, it's common for the crank length of triathlon bikes to be slightly shorter than road bikes and for them to adopt specific saddles that better cater for the pronounced anterior pelvic tilt that comes from bending forward. These small changes open up the angle of the hips, increasing comfort that enables riders to stay in that position for long periods.
The most reliable way to know what is the best triathlon bike for you is to work with our professional bike fitter to establish your riding position first and then use the information from the fitting to help find which model frames fit you best. We have the experience and knowledge to be able to make recommendations that will take the guess work out of the process and that you know will fit and work well for you – thus saving money and helping your bike work as it was designed.
