Product Description
FELT IAx ADVANCED | ULTEGRA Di2
Versatile Performance. World-Class Aerodynamics.
The Felt IAx Advanced takes the legendary speed of the IA platform and makes it more accessible without sacrificing velocity. Engineered with UHC Advanced carbon, the IAx features a streamlined silhouette designed to conquer crosswinds and optimize airflow. Paired with the ultra-reliable Shimano Ultegra Di2 12-speed electronic groupset and a staggered Reynolds Carbon wheelset, this bike is the perfect partner for athletes looking to set personal bests from Olympic to IRONMAN distances.
Precision Engineering for Triathletes
- UHC Advanced Carbon Frame: A high-performance layup that offers the perfect blend of vertical compliance for long-course comfort and lateral stiffness for power transfer.
- Shimano Ultegra Di2 R8150: Seamless, instantaneous electronic shifting allows you to stay in your aero tuck while maintaining the perfect cadence.
- Reynolds AR58/62 Carbon Wheels: A staggered rim depth (58mm front / 62mm rear) provides elite-level aerodynamics while maintaining stable handling in gusty conditions.
- TRP Hydraulic Disc Brakes: Specialized TRP HD-T910 hydraulic system provides confident, one-finger braking from the base bars.
- Adjustable Cockpit: The Devox Bayonet system allows for extensive fit adjustments, ensuring you find the most sustainable and aerodynamic position.
