Felt IA Advanced 105 | Rim Brake | Carbon Triathlon Bike

The Felt IA Advanced 105 brings the proven aerodynamic pedigree of the world-championship-winning IA platform into an accessible race-ready package. Designed from UHC Performance carbon fiber, the IA Advanced delivers the stiffness, stability, and aerodynamic efficiency athletes depend on for long-course triathlon racing.

The streamlined frame and fork shaping were developed through extensive CFD analysis, wind tunnel validation, and real-world testing. The result is a bike that maintains speed efficiently on straightaways and remains composed in crosswinds. With integrated CALpac 2.0 and BTSpac storage, nutrition and tools remain accessible without disrupting airflow.

This build pairs the IA Advanced chassis with Shimano’s reliable 105 R7000 2x11 drivetrain for smooth shifting and consistent performance. Direct mount rim brakes keep weight low and offer predictable, easy-to-maintain braking. The Devox Bayonet aero cockpit and ISM PS1.1 saddle provide adjustability and comfort for sustained time in the aero position. Devox WheelRRS.A1 wheels and Continental Grand Sport Race tires complete a responsive, race-oriented wheel setup.

If you want an aerodynamic carbon triathlon platform with dependable components and proven race performance, the Felt IA Advanced 105 is a strong option for training and racing.
