FeltIA 2.0
The IA 2.0 is Felt's triathlon bike. A removable hydration reservoir sits in the hump of the top tube, with nutrition storage on the top tube and a tool compartment in the seat tube. FRD and Pro builds use the FRD 12K carbon frame. The Expert and Race builds use a lower-grade UD Carbon STD frame with the same geometry, listed as a separate variant.

Our verdict
Overall
out of 100, average of 7 categories
A complete long-course package: a refillable top-tube reservoir, nutrition and tool storage, plenty of cockpit adjustment and a frame with two Ironman world titles. The gel box is small, tyre clearance isn't published and the seatpost and basebar are Felt-specific, but few tri bikes carry this much without add-ons.

Good to know
Fit
Seat angle gets slacker as size goes up, from 79.5° on the 48 to 77.5° on the 58. Fork offset changes from 50 mm on the 48 and 51 to 45 mm on the 54 and larger.
SourceIntegration
The THIRSTpac sits in the hump of the top tube. Its quick-fill port means it can be topped up while riding, and a straw runs to the cockpit. Road.cc gives 0.9 L, while Cyclenews quotes 26 oz.
SourceIntegration
Cyclenews found the top tube gel compartment held only a few gels. The seat tube compartment holds just enough tools for a tube change.
SourceCompatibility
Felt specs 25 mm Continental tires on current builds. Cyclenews' test bike ran 28 mm Continental GP5000s. Felt does not publish a maximum tire width.
SourceRacing
Daniela Ryf rode the IA 2.0 to victory at the Ironman World Championship held in St George in May 2022.
SourceRacing
Solveig Løvseth rode the FRD frame to the 2025 Ironman World Championship title, with the fastest bike split of the day.
SourceHistory
The IA 2.0 replaced the original Felt IA in 2022. Felt claimed it was 4% faster in the -12.5° to 12.5° yaw range and 1.9% faster across -20° to 20°.
SourceVersions
FRD and Pro builds use the FRD 12K Carbon Light frame and fork. The Expert and Race builds use a UD Carbon STD frame and fork with the same geometry. Claimed complete weights in size M are 9.37 kg (FRD Dura-Ace), 9.5 kg (Pro Ultegra) and 10.3 kg (Expert Ultegra).
