Felt IA 2.0 FRD Dura-Ace Di2 Bike

The Felt IA 2.0 FRD Dura-Ace Di2 Bike sits at the top of Felt's triathlon lineup — a machine built around one goal: the fastest bike split possible. FRD is Felt's highest-tier designation, reserved for framesets constructed with their lightest, most advanced 12K carbon layup. The combination of exceptional stiffness-to-weight ratio, a radical aero silhouette, and a full race-ready build makes the IA 2.0 FRD the most formidable triathlon bike Felt produces.

This is a bike with race-proven credentials. The IA 2.0 is the machine that carried Solveig Løvseth to the 2025 IRONMAN World Championship title — including the fastest bike split of the day. The frame's aero profile is matched by thoughtful on-course integration: the cockpit and frame design accommodate hydration and nutrition storage within the aerodynamic silhouette so you can fuel without breaking position. On a long-course race, that kind of design discipline translates directly into time saved.

Felt has matched the FRD frame with a build that does it justice. A complete Shimano Dura-Ace Di2 R9250 drivetrain delivers flawless 12-speed electronic shifting under any load, and the Shimano SW-R9160 Di2 TT/Tri remote shifters let you stay deep in the aerobars and change gears without ever hunting for a lever. The wheelset is a deliberate asymmetric pairing: a Vision Metron 60 up front for crosswind manageability, and a Vision Metron 91 SL I21 in the rear to maximize aerodynamic advantage on straight-line efforts. Continental GP5000 TT tires in 700x25 complete the setup — a choice trusted by professional triathletes worldwide for their balance of speed and reliability.

The Shimano Dura-Ace R9200 crankset comes equipped with a 4iiii Dual-Sided Power Meter as part of the standard specification — not as an add-on. Dual-sided measurement captures true left/right power balance rather than extrapolating from a single leg, which matters both in training and when pacing a race effort across a 90 or 180-kilometer bike leg. Hydraulic disc brakes via the Shimano Dura-Ace R9180 calipers and 140mm CL800 Centerlock rotors provide confident, consistent stopping through technical turns and fast descents with no fade under race conditions.

Design Benefits

1. FRD 12K Carbon Light frame and fork — Felt's top-tier carbon construction delivers the lightest, stiffest chassis in the IA lineup. Maximum power transfer, minimum weight penalty, and an aero profile shaped for speed from every angle.
2. Asymmetric Vision Metron wheelset — the 60mm front and 91mm rear combination is a deliberate engineering choice for long-course triathlon. The shallower front wheel is more manageable in crosswinds while the deep-section rear capitalizes on aerodynamic gains where straight-line speed matters most.
3. 4iiii Dual-Sided Power Meter — built directly into the Dura-Ace crankset, dual-sided measurement gives you accurate left/right power balance. Compared to single-sided estimates, you get a more complete and reliable picture of your effort — both in training and when executing a race-day pacing strategy.
4. Shimano Dura-Ace Di2 R9250 throughout — the latest Dura-Ace delivers Shimano's most precise and consistent electronic shifting. The SW-R9160 Di2 TT/Tri remote shifters keep your hands on the aerobars and your body in position while you shift through 12 speeds.
5. Integrated hydration and nutrition storage — the IA 2.0's frame and cockpit are designed as a unified aero system with integrated storage for on-course fueling. You stay in position. You stay fast.

Final Take

The Felt IA 2.0 FRD Dura-Ace Di2 is not a versatile all-rounder — it's a race weapon. Felt engineered every element of this bike around a single objective: the fastest possible bike split. The FRD carbon, the asymmetric Vision Metron wheels, the integrated Dura-Ace Di2 drivetrain with dual-sided power — it all points in one direction. For a serious triathlete ready to race at the highest level, this is the Felt IA 2.0 FRD.
