Felt
IAIAx | Advanced | Rival eTap AXS
The original Felt IA was one of the defining triathlon platforms of the mid-2010s and remained in service for an unusually long run, from its 2014 introduction through the final pre-IA 2.0 years. It was built around a deep-section, non-UCI frame shaped specifically for triathlon rather than time trial rule compliance, with a proprietary front-end and nose-cone treatment that gave the bike its distinctive silhouette. Key design elements of this generation included horizontal rear dropouts, a proprietary seatpost, and modular storage such as CALpac and BTSpac, reflecting an era when integrated nutrition and flat-kit solutions were becoming central to tri bike design but had not yet been fully molded into the frame itself.

The later IA range was offered in several IAx Advanced complete-bike builds spanning mechanical, electronic, and wireless electronic drivetrains. The lineup included 105, 105 Di2, Rival eTap AXS, and Ultegra Di2 versions, giving buyers a clear progression from a more accessible mechanical setup to higher-end electronic options. That spread made the platform available to a broad range of triathletes without changing the underlying frame concept.
