Built around Felt’s proven UHC Advanced carbon platform, the IAx Advanced delivers aerodynamic efficiency without sacrificing fit flexibility or long-distance comfort. The redesigned front-end removes unnecessary complexity, making travel, maintenance, and position adjustment significantly easier for real-world triathlon athletes.
Shimano 105 Di2 electronic shifting transforms every acceleration into smooth, instant gear changes. Combined with the Reynolds AR58/62 deep-section wheelset, the IAx slices through headwinds while maintaining confident stability at race pace. Hydraulic disc brakes provide controlled stopping power across technical descents and unpredictable weather conditions.
From training blocks to Ironman race day, the IAx Advanced creates a more sustainable aero position, helping riders conserve energy while maximizing speed over long distances.
