Product Description

FELT IAx ADVANCED | ULTEGRA Di2

Versatile Performance. World-Class Aerodynamics.

Crafted to merge surgical digital gear engagement with wind-tunnel-validated deep-section speed, the 2026 Felt IAx Advanced Ultegra Di2 turns grueling long-course bicycle legs into controlled high-velocity dominance. Marrying a vibration-damping UHC Advanced carbon frame with pro-tier semi-wireless electronic actuation, staggered aerodynamic carbon hoops, and an infinitely tuneable fit architecture, it keeps the athlete locked in a low-drag posture designed to preserve fresh running legs for the transition zone.

Precision Engineering for Triathletes

  • UHC Advanced Composite Chassis: High-modulus carbon fiber layup engineered to balance vertical road-shock compliance for long-course comfort with direct lateral bottom-bracket power transfer.

  • Shimano Ultegra Di2 R8150 12-Speed: Pro-tier semi-wireless digital actuation delivering instantaneous, load-tolerant gear changes to maintain cadence lock inside the aero tuck.

  • Reynolds AR58/62 Staggered Carbon Hoops: Deep-section aerodynamic profile (58mm front / 62mm rear) tuned to maximize high-speed sail thrust while preserving predictable crosswind handling.

  • TRP HD-T910 Triathlon Hydraulic Stopping Suite: Specialized hydraulic braking architecture engineered for finger-light, one-finger modulation directly from the aero basebars under technical deceleration.

  • Devox Bayonet Multi-Axis Fit Platform: Comprehensive adjustability ecosystem engineered to dial in a deeply personal, sustainable, and low-turbulence rider aerodynamic profile.
