The Felt IAx Advanced Ultegra Di2 is a masterpiece of aerodynamic efficiency, specifically designed for serious triathletes and time trialists who want to maximize their performance. The foundation of this machine is the UHC Advanced carbon frame, optimized in the wind tunnel to minimize air resistance and convert every pedal stroke into pure speed. This bike is not just an upgrade; it's a dedicated platform for athletes chasing the podium and breaking personal records, with the proven IAx geometry providing a stable and aggressive riding position.

This version is equipped with the ultra-reliable Shimano Ultegra Di2 2x12-speed electronic groupset, ensuring lightning-fast and flawless shifting performance, even under heavy load. Confidence on descents and technical turns is guaranteed by the powerful TRP HD-T910 hydraulic disc brakes, which provide consistent stopping power in all weather conditions. The IAx rolls on a custom Reynolds AR58/62 DB carbon wheelset, which is tubeless-ready and offers a perfect balance between aerodynamic advantage and stability in crosswinds.

Every detail of the Felt IAx Advanced is focused on the needs of the triathlete. The Devox Bayonet 3.1 cockpit with carbon extensions offers extensive adjustment options for a perfect, personalized fit. For long distances, the bike features integrated storage solutions, including the IA CALpac 2.0 on the top tube for nutrition and the IA BTSpac behind the seatpost for tools. Combined with the comfortable ISM PS1.0 saddle, this is the ultimate machine to leave the competition behind.
