We can tell you that the IA is the most aerodynamic bike in the world. We can also say that it’s the best-handling triathlon bike on the planet. But what we should really mention is that the IA has won the Kona World Championship a staggering six times in a row, and it’s set both new bike course and overall course records across the lava fields of Hawaii. So, really, what else do you need to know?

Buy it if:
You want the winningest bike in triathlon, one that emphasizes aerodynamic efficiency, ride quality, and real-world usability, all in equal measure.
