Felt IAx 105 SC55 TT Bike
The IAx is the updated version of Felt's famous IA. By eliminating the frame/fork nose cone and complicated one-piece front end Felt provide a better fit across a wider range of athlete levels. Race-ready with the advantages of a streamlined and simplified design to make bike set-up easier and to keep things simple with overall maintenance and travel to events.
The optimized IAx is meticulously crafted for aerodynamics. Through extensive CFD modelling, rigorous wind tunnel testing, and real-world prototype validation, Felt 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, Felt have engineered one of the fastest triathlon bikes with the simplicity reminiscent of a standard road bike.
Shift To A New Gear
Shimano's R7100 105 12 speed groupset offers the reliable shifting and quality for which Shimano is known. This latest mechanical group offers a wide 12 speed gear range and powerful brakes for a great ride.
A Precise, Dialed Fit
With rider position a key part of the performance equation, you'll be able to fully dial-in your set-up with an easy-to-adjust front end. The aluminium stem, base bar, and extensions offer individual adjustments to get your best riding position.
