Felt IAx Advanced 105 Triathlon Bike – 2024

The Felt IAx Advanced 105 is built for triathletes who demand cutting-edge aerodynamics, race-ready performance, and a perfect balance of speed and comfort. Known as the gateway to Felt’s legendary IAx platform, this 2024 model delivers the advanced engineering that has carried professional athletes to Kona podiums—at a price point that makes it attainable for ambitious age-group racers.

Engineered in the wind tunnel and refined on the racecourse, the Felt IAx Advanced 105 triathlon bike incorporates a lightweight Advanced carbon frame with aerodynamic tube shapes and integrated design features. The result is a bike that slices through the wind while maintaining stability, making it ideal for both Ironman-distance events and local time trials.

Compared to higher-tier builds such as the Felt IAx Advanced Ultegra Di2 and the Felt IAx Advanced Rival eTap AXS, this model with Shimano 105 mechanical shifting offers unmatched value. It’s a serious performance machine for athletes who want the same winning DNA of the pro-level IAx series without the premium cost of electronic shifting.

If you’re looking for a Felt IAx Advanced review, most riders agree this bike provides aerodynamic efficiency, predictable handling, and rider-friendly integration for hydration and storage. The Felt IAx Advanced 105 Di2 and other models are also available, but this version shines for delivering professional-grade performance at an entry-level race price.
