AERO EXCELLENCE FOR EVERYONE. IAx provides a more affordable and straightforward option for most of the triathletes. Despite the advancements of our IA 2.0 platform, the standard IA design remains an iconic benchmark for speed and performance. This is why we drew inspiration from it while developing the new IAx. Tested to be as fast as the iconic IA, the IAx differs only in the frontal area. We opted for a simpler and conventional fork design, foregoing the well-known bolt-on aero nose cone featured on the IA and IA 2.0. 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. AERODYNAMICS The newly optimized IAx is meticulously crafted for aerodynamics. Through extensive CFD modeling, rigorous wind tunnel testing, and real-world prototype validation, we have unequivocal confidence in the IAx's speed. Whether achieving straight-line velocity or effortlessly navigating crosswinds in the aero position, the IA empowers riders to excel and deliver peak performance on race day. SIMPLE, BUT FAST. The IAx introduces a conventional front fork, eschewing bolt-on nose cones and add-on aerodynamic covers. Stripping away the non-essentials, we've engineered one of the fastest triathlon bikes with the simplicity reminiscent of a standard road bike. We understand the satisfaction of having a sleek and easy-to-assemble bike, as we've all been there, appreciating the uncomplicated joy of a seamless setup. MORE STORAGE. MORE AERO. The New IAx comes with the integrated CALpac 2.0. This storage unit positioned on the top tube offers space for all of the riding essentials with quick and easy access to gels and bars. The New IAx also includes the BTSpac set behind the seat tube. This is ideal for a flat repairs and/or on-the-go tool kit, or any other items that a rider doesn't require at-hand, all in an aero package.
