Our very first bike was made for one of the greatest triathletes in historyPaula Newby-Fraserwho rode her stealth black Felt B2 to multiple world championship victories. Since then, weve never stopped pursuing the ideal triathlon racing machine. The first IA revolutionized the triathlon world when it debuted. Despite advancements via our IA 2.0 platform, the standard IA remains a reference point for speed and performance.

The IA remains one of the most aerodynamic bikes in the world. Its precise handling, stable performance in windy conditions, and its low-drag profile still lays claim to winning the Kona World Championship a staggering six times in a row. It still holds both bike and overall course records across the lava fields of Hawaii to this day. If speed is your thing, you are sure to enjoy the IA.
