2025 Felt IAx Advanced Ultegra Di2 - Turquoise
FeltThe latest version of our venerable IA platform, the IAx sets a new standard for ease-of-use and dialed performance for those who crave speed.
The famous IA speed newly-configured for performance
The IA has been the most successful triathlon platform Felt has ever created. As we introduced the IA 2.0 and its industry-leading technology, we updated the prior IA to become the IA "x". This "new" version eliminates the nose cone and one-piece front end from the old version to help with more fit options across a wider range of athlete levels.
FEATURES:
Shimano electronic shifting excels
IA speed in a streamlined package complete with Shimano's performance-oriented Ultegra Di2 12-speed groupset. Dialed shifting and beautiful ergonomics ensures a great ride and the technology triathletes demand.
Aero-Optimized Wheels
Reynolds' AR58/62 DB wheelset is custom-made for us to ensure the best of aerodynamics and ride quality whether you are training or racing. Premium Continental Grand Prix SL tires offer a sure-footed performance.
Precision Fit Is Dialed
Our aluminum stem and base bar are paired with carbon extensions to provide an easy-to-adjust set up on your front end. With fit a premium in triathlon, you'll have the options for your unique position.
